Abstract
An interactive grid-based graphical trading system for use in securities trading provides a dynamic, visual display of trading data consisting of orders, quotes and indices, for any security and for any number of market participants. The trading data are plotted on a grid consisting of cells arranged in rows and columns, which are associated with specific parameters. Distinct visual presentation styles are used, and differences in the price parameter are represented spatially. The values of the price and other parameters associated with the same orders and quotes are mapped against the values associated with the rows and columns of the grid. A trader may place or modify trading orders by interacting with the trading data displayed on the grid, and with specific GUI objects displayed on the same grid. Trading instructions are generated and transmitted to a market participant, in a manner transparent to the trader.

FIELD OF THE INVENTION
[0001] The present invention relates to software which may be employed by individual traders who trade in real time with respect to a specific market, as buyers or sellers. The present invention provides an interactive grid-based graphical trading system comprising a "checkerboard" matrix of intersecting one or more rows and one or more columns representing, interchangeably, price increments along one axis and one or more markets or market participants along a second axis, for any specific security. The resulting grid displayed on a suitable display device is associated with market information so that a buying or selling instruction may be given. Moreover, since the display functions in real time, the user receives a dynamic graphical representation of existing market conditions at that instant in time with respect to any security. Similarly, the trader using the interactive grid-based graphical trading system may effect an order placement or order modification transaction by dragging and dropping an icon or any suitable GUI object into the "checkerboard" matrix. The user can then subsequently reposition the order graphically in terms of price and/or market participant.
BACKGROUND OF THE INVENTION
[0002] There are a number of trading systems, and a number of individuals, who engage in real time day-to-day or minute-to-minute security trading. Very often, such individuals are referred to as day traders.
[0003] Moreover, many stock brokers have an interest or duty to observe the dynamics of the market, including price fluctuations and volume of trading in any security.
[0004] However, even some proprietary software which is available for use by such individuals as day traders and stock brokers may require considerable key stroke input, and may not provide a dynamic display which indicates not only current market conditions but, by being observed over a period of time, such dynamic display would indicate what the market is doing with respect to a particular security. For example, Bank of Montreal Investorline.TM. requires that a user shall first enter the ticker symbol for a selected security, then enter the price, then the number of shares, and finally click on a confirmation button. As will be explained hereafter, the present invention permits the user to effectively drag and drop an icon representing at least one selected security, with a selected trading order, over a grid to a selected cell having a selected price, and dropping the icon so as to effect the desired trading order.
[0005] Graphical displays in keeping with the present invention will indicate whether the market is moving up or down, whether there is a high volume or low volume of trades occurring at the present time, and even the number of buy or sell orders that may be in place, and at what price, as they may be handled by any market participant.
[0006] The trader to whom the present invention is particularly directed is usually, but not necessarily, a sophisticated trader, who is interested in the dynamics of the market, and who is interested in obtaining data for any selected security at any instant in time, as well as to watch the changes in market conditions as they may affect that security over a period of time.
[0007] The present invention provides means, including particularly a graphical user interface, to permit the trader to achieve the goals set forth above.
[0008] While the present invention is particularly directed to an interactive grid-based graphical trading system for use in trading securities, it necessarily includes all of the appropriate physical architecture and logical architecture at least, in functional terms that are necessarily order to facilitate operation of the present invention.
[0009] Of course, it will be understood that the present invention contemplates the existence throughout the network of traders and market participants, of secure and high speed communications channels, and of sufficiently powerful and high speed computer hardware to function appropriately and to assure seamless and transparent functionality and operation of the market overview and security trading functionalities of the present invention. The present invention also contemplates that proprietary software which embodies features, functions, and particulars of the teachings herein, will be resident in any computer hardware at the site of any trader practicing or operating this invention.

Also, any trader may select any particular security for which data are electively required, at any instant in time.
[0013] The interactive grid-based graphical trading system includes first process means that function to send transaction instructions through communication channels to the backend system used by any market participant. It also receives messages from the backend system through communication channels. Furthermore, the grid-based graphical interface includes second process means that function to receive, process, and display market trading data, and messages, to any trader.
[0014] The market trading data includes information chosen from the group of market trading data consisting of: order data as to buy, sell, or other trading orders existing at that instant in time for any selected security or group of securities, quote data as to bid and ask prices, volume, market participant identifiers, and other parameters, existing at that instant in time for any selected security or group of securities. Also, the market trading data is transmitted to each grid-based graphical interface at the site of any participating trader from the backend system of any market participant in computer-readable electronic format.
[0015] Moreover, the interactive grid-based graphical trading system includes third process means that function to transform market trading data received from any backend system, at any instant in time, into a graphical representation for display on any display device. The graphical representation includes at least one grid having a plurality of cells arranged in an array of at least one row or at least one column. A row is an arrangement of horizontally adjacent cells with at least one common property. A column is an arrangement of vertically adjacent cells with at least one common property. Each cell within the plurality of cells belongs to one row and one column.
[0016] A plurality of cells is arranged in a matrix chosen from the group consisting of: a plurality of rows and at least one column, a plurality of columns and at least one row. The plurality of rows, or the plurality of columns, are associated with an axis representing price.
[0017] Any cell may be associated with the market trading data, and contains a graphical representation of market trading data, which is associated with a specific price or range of prices.
[0018] Each cell along the price axis indicates a price or price range for which the market trading data exists. The other of at least one column or a least one row is indicative of a specific criterion chosen from a plurality of selected criteria within which the market trading data may be categorized as to price or a range of prices.
[0019] Any trader can place, or modify, an order for a selected security or group of securities, over which that trader has discretion. This is done by interacting with the grid-based graphical interface. The interaction can be accomplished by a drag and drop operation, and the order or the quote is represented graphically in a cell.
[0020] The communication channels may be network-based, so that at any instant in time a connection between any trader and a backend system of any market participant may be persistent or intermittent.
[0021] Typically, the interactive grid-based graphical trading system network is the Internet.
[0022] Moreover, any cell in a plurality of cells may be assigned specific visual or graphical attributes or properties chosen from the group of graphical or visual attributes or properties consisting of: color, border, label indicator, graphic overlay, text overlay, and combinations thereof.
[0023] The specific attribute or property assigned to any cell is a function of the specific market trading data associated therewith.
[0024] Furthermore, any trader can modify the parameters of any order over which that trader has discretion, for a selected security or group of securities being displayed on the grid-based graphical interface, at any instant in time. This is accomplished by selecting a relevant order cell using a pointing device interactive with the grid-based graphical interface, and dragging and dropping the selected relevant order cell to a destination cell. The dragging and dropping of the selected relevant order cell causes the grid-based graphical interface to activate the first process means to send transaction instructions comprising an amendment of previous specific trading parameters associated with the relevant selected order.
[0025] The second process means may electively effect an alteration of the specific visual or graphical properties assigned to both the relevant order cell and the destination cell.
[0026] The axis associated with price maybe presented as a specific price range above and specific price range below the last traded price of a selected security or groups of securities at any instant in time. Furthermore, the last traded price is present on the price axis.
[0027] Furthermore, in the interactive grid-based graphical trading system of the present invention, the communication channels may include middleware used by any market participant.
[0028] In the interactive grid-based graphical trading system of the present invention, the price difference between two adjacent cells along the price axis may be the minimum price variance (MPV), or a multiple of the minimum price variance, for any selected security or groups of securities being displayed at any instant in time.
[0029] Market trading data representing specific order data and quote data for a selected security or group of securities may be presented in a matrix comprising a plurality of rows and a plurality of columns of cells. Each row of cells or each column of cells is associated with a specific price or range of specific prices for any given security or group of securities. The market trading data being displayed in any cell of the row of cells or the column of cells includes a plurality of specific components related to selected market parameters associated with the data.
[0030] The specific order data and specific quote data are linked and associated to a respective one of a set of GUI objects in the grid-based graphical interface at each trader's location.
[0031] If middleware is present, it functions to translate data and instructions sent over any communication channel into a format that is understood by the grid-based graphical interface at any trader's location, or a respective backend system at any market participant's location.
[0032] The middleware has components therein to translate any trading order instruction issued from a trader, or to translate messages from a market participant.
[0033] Typically, the grid-based graphical trading interface for any trader has a data storage. Also, the middleware may have an associated data storage relevant to the system.
[0034] In the interactive grid-based graphical trading system of the present invention, a selected security for the trading data may be displayed at any instant in time, and may be changed to another selected security by any trader, at any instant in time.
[0035] The trading data for any selected security may be displayed at any instant in time by any trader. It is constantly updated having regard to new trading data being received by the grid-based graphical interface for that selected security.
[0036] Any backend system will perform at least the following tasks: account management for each trading account, processing trading orders for each valid transaction which a trader issues; order execution, whereby each valid transaction issued by any trader is executed; data dissemination, whereby market trading data concerning any security is delivered to any trader's grid-based graphical interface, and backend system management for monitoring and maintaining security and operation of the backend system.
[0037] Each market participant may be chosen from the group consisting of stock brokerages, electronic communication networks (ECN's), stock exchanges, commodity exchanges, futures exchanges, bourses, and auction houses.

[0039] In the present invention, data communications over the communications channels are in keeping with selected protocols which are established to standardize data interchange between the grid-based graphical interface communicating over the communications channels, with any backend systems. Furthermore, the data communications may electively use secure data encryption modes.
[0040] The middleware may further perform the task of connection management, whereby connection requests from any trader's grid-based graphical interface to the backend systems are granted or rejected, and where existing connections are monitored and managed.
[0041] The interactive grid-based graphical trading system of the present invention includes a display panel, where the display panel contains individual icons representing each security held by any respective trader in that trader's account.
[0042] In the interactive grid-based graphical trading system of the present invention, each icon may represent a security position held by that trader in that trader's account. Also, any icon may be dragged and dropped onto a specific valid cell of the grid-based graphical interface. The drag and drop operation on any selected icon causes the grid-based graphical interface to issue transaction instructions to a respective backend system through the middleware.
[0043] Furthermore, a display panel is associated with the interactive grid-based graphical trading system at any trader's location, where the display panel contains GUI objects to represent any monetary value or security which is held in any trader's account. In addition, the interactive grid-based graphical trading system includes fourth process means that permits the monetary value or security associated with a respective GUI object to be separated into a plurality of GUI object, which may represent in total the monetary value or security, as elected by the trader.
[0044] Moreover, the GUI objects may be used to represent specific quantities of units of any selected security, and additional GUI objects may be used to represent selected amounts of cash. In each instance, each GUI object is linked to data representing the specific quantities of units of any selected security, or representing the selected amounts of cash in software at the trader's location.
[0045] Typically, the grid-based graphical interface is application software, which is available through a computer at the respective trader's location.
[0046] In keeping with the present invention, one of the plurality of rows or one of the plurality of columns of cells is associated with at least one market participant, so that each cell can represent one or more specific quote data or order data being posted by at least one market participant for the selected security or item being displayed at any instant in time.
[0047] Cells representing at least one buy order or buy quote at or near the bid price, and different cells representing at least one sell order or sell quote at or near the ask price, which thus represent market trading data being posted by a market participant for a selected security, are simultaneously displayed.
[0048] Also, any cell that represents at least one order associated with at least one market participant at the respective specific price or range of specific prices indicated by that cell, is displayed with selected graphical properties.
[0049] The graphical properties of the present invention may be chosen from the group consisting of: a distinct color, a distinct shape, distinct text labels, and combinations thereof. The graphical properties identify the cell as representing data for at least one order or at least one quote.

Furthermore, the additional data may be chosen from the group of data consisting of: the number of orders associated with the given cell, the total volume or number of contracts, the total dollar value of the orders outstanding, the total volume of the orders traded, and the lot size outstanding, and combinations thereof.
[0052] In keeping with the present invention, the data displayed on a display panel on the display device at any trader's location may include text based quote data and related summary statistics for a selected security or group of securities at any instant in time.
[0053] Furthermore, text based quote data and related summary statistics may include data chosen from the group consisting of: the exchange or market where the selected security is being traded, the current bid price, the current ask price, the current bid size, the current ask size, the last trade price, the size of the last transaction in terms of the number of units of the selected security traded, the change in the price of the last trade with respect to the closing price of the previous session, the volume in terms of the number of units of the selected security that had been traded during the current trading session, the high price of the session, the low price of the session, the opening price of the session, and combinations thereof.
[0054] In the interactive grid-based graphical trading system of the present invention, the text based quote data may be categorized as Level 1 data.
[0055] Also, in the interactive grid-based graphical trading system of the present invention, a standard protocol may define the format of the instructions and data that are exchanged between the interactive grid-based graphical trading system and any backend system of any market participant.
[0056] Typically, in the interactive grid-based graphical trading system of the present invention, a standard protocol may be based on eXtensible Markup Language (XML).
[0057] Moreover, in the interactive grid-based graphical trading system of the present invention, data from a backend system may be associated with a respective GUI object at any trader's grid-based graphical interface.
[0058] Within the interactive grid-based graphical trading system, a plurality of grid-based graphical interfaces are presented in a plurality of overlapping tab pages. The tab for any of the pages can thus be selected. The plurality of tab pages are contained in at least one display panel on the display device, where at least one grid-based graphical interface is associated with one tab page or one display panel at any instant in time.
[0059] Also, the specific visual or graphical properties of any tab page may change at any instant in time, as a result of a specific event occurring.
[0060] Furthermore, the specific event may be triggered by specific market or user defined criteria related to said tab page, or to the securities associated with the tab page.
[0061] Additionally, a transaction may be effected by dragging and dropping GUI object representing a specific trading instruction, for a specific security, from one display panel on the system to the grid-based graphical interface.
[0062] Moreover, a transaction may be effected by dragging and dropping a GUI object representing a specific trading instruction, for a specific security, from a grid-based graphical interface to an alternate GUI object.
[0063] In the interactive grid-based graphical trading system of the present invention, a specific trading instruction may effect a cancel order instruction for the specific security.
[0064] Furthermore, a transaction instruction which changes a parameter associated with an existing open order may be translated by middleware, so as to appear to the trader as a single seamless instruction.
[0065] Still further, any trading order transaction may be effected by dragging and dropping a GUI object which is representative of a specific transaction onto a valid cell of the grid-based graphical interface, where the first process means will issue a respective transaction instruction through a respective communication channel to a respective market participant.
[0066] Also, in the interactive grid-based graphical trading system of the present invention, any trading order transaction may be effected by dragging and dropping a selected GUI object representative of an intended transaction onto a destination cell on the grid-based graphical interface. The dragging and dropping of the selected GUI object causes the grid-based graphical interface to apply the first process means, so as to result in the placement of a new order with a market participant. Furthermore, if the new order includes specific trading parameters, the second process means may electively alter the specific visual or graphical properties assigned to both the selected GUI object and the destination cell.
[0067] In the interactive grid-based graphical trading system of the present invention, any trading order transaction which has been placed on the grid-based graphical interface but not yet filled, may be cancelled by dragging the respective GUI object associated with the order outside the grid-based graphical interface.
[0068] Moreover, any open order for a specific security for which a trader has discretion, may be cancelled by dragging and dropping a selected cell associated with the specific open order from the grid-based graphical interface to a selected GUI object associated with a cancel transaction order. The dragging and dropping of the cell causes the interactive grid-based graphical trading system to apply the first process means, so as to result in the placement of a cancel order instruction with the associated market participant. The cancel order instruction includes specific parameters, where the second process may electively alter the specific visual or graphical properties assigned to both the selected GUI object and the selected cell.
[0069] Also, the price values represented by the price axis maybe electively associated with an absolute price or price range, or a relative price or price range.
[0070] In addition, the adjustment of the price values, and the alteration of the associated visual or graphical properties of each cell, along the price axis, is under the control of the third process means.
[0071] Within the grid-based graphical interface, the relevant visual or graphical properties of any cell associated with either order data or quote data will dynamically change in response to an amendment of its original properties, and in relation with the values represented by the given cell's respective axes.
[0072] Moreover, the displayed price range for any price axis may be automatically determined according to a set of relevant market trading data.
[0073] In addition, the range of price values which are displayed along the price axis, and the price value for a selected row or column, may be determined for each selected security at any instant in time as a factor of one of the criteria chosen from the group consisting of: the closing price for that security during the prior session, the opening price for that security during the current session, the highest price paid for that security during the current session, the lowest price bid for that security during the current session, and the last price paid for that security, and combinations thereof.

[0256] The interactive grid-based graphical quote presentation system of claim 77, wherein additional data is associated with each cell; whereby the additional data can be electively displayed by clicking or right-clicking on the cell; and wherein the additional data is chosen from the group of data consisting of: the number of orders associated with the cell, the total volume or number of contracts, the total dollar value of the orders outstanding, the total volume of the orders traded, and the lot size outstanding, and combinations thereof.
[0257] The data displayed on a display panel on a display device at any trader's location may include text based quote data and related summary statistics for a selected security or group of securities at any instant in time.
[0258] That text based quote data and related summary statistics may include data chosen from the group consisting of: the exchange or market where the selected security is being traded, the current bid price, the current ask price, the current bid size, the current ask size, the last trade price, the size of the last transaction in terms of the number of units of the selected security traded, the change in the price of the last trade with respect to the closing price of the previous session, the volume in terms of the number of units of the selected security that had been traded during the current trading session, the high price of the session, the low price of the session, the opening price of the session, and combinations thereof.
[0259] Of course, the price values represented by the price axis may be electively associated with an absolute price or price range, or a relative price or price range.
[0260] If so, the adjustment of the price values, and the alteration of the associated visual or graphical properties of each cell, along the price axis, is typically under the control of third process means.
[0261] In the interactive grid-based graphical quote presentation system of the present invention the relevant visual or graphical properties of any cell associated with quote data may dynamically change in response to an amendment of its original properties, and in relation with the values represented by the cell's respective axes.
[0262] The displayed price range for any price axis may be automatically determined according to a set of relevant market trading data.
[0263] If so, the range of price values which are displayed along the price axis, and the price value for a selected row or column may be determined for each selected security at any instant in time as a factor of one of the criteria chosen from the group consisting of, the closing price for that security during the prior session, the opening price for that security during the current session, the highest price paid for that security during the current session, the lowest price bid for that security during the current session, and the last price paid for that security, and combinations thereof.
[0264] The criteria for which at least one column of a matrix is determined, may be chosen from the group consisting of: a market participant, a security, a component of an index, an index, aggregate trading data from a plurality of market participants, the trading activity of a market participant during the current session, the trading activity of a component of an index, the pending orders of the market participant at any instant in time, aggregate buy order data from a plurality of market participants, aggregate sell order data from a plurality of market participants, and combinations thereof.
[0265] Of course, in any interactive grid-based graphical quote presentation system hereof, any axis not associated with the price axis can represent any market criteria other than price.
[0266] In an interactive grid-based graphical system of the present invention, the grid-based graphical interface for any trader may have memory means associated therewith, whereby a record function stores market trading data in the memory at selected time intervals. Thus, a replay function for the data, to recall that market trading data associated with the selected time intervals, and to graphically display the data over a selected time period, may be selectively invoked by a trader.
[0267] Of course, any specific color, text label, pattern, shape, or texture may be associated for each different type of trading order which is displayed in any cell.
[0268] Thus, any specific color, texture, text label, shape, or pattern may be associated with each cell representing an ask price, or a higher price than the ask price, for any selected security in any given market; and wherein a different specific color, texture, text label, shape, or pattern may be associated with each cell representing a bid price, or a lower price than the bid price, for any selected security in any given market.
[0269] The interactive grid-based graphical quote presentation system of the present invention further include fourth process means that function to transform NASDAQ Level II data for any selected security, at any instant in time, into a format suitable for display on the grid-based graphical interface.
[0270] The interactive grid-based graphical quote presentation system hereof may also further include fifth process means that function to transform a stock exchange's market depth data, or an Electronic Communication Network's (ECNs) electronic order book for any selected security, at any instant in time, into a format suitable for display on the grid-based graphical interface.
[0271] The replay function noted above maybe controllable so that playback of market trading data is accelerated in time, or de-accelerated in time, and displayed visually.
[0272] Also, the market trading data which is displayed for a selected security at any instant in time can be electively filtered to display a subset of the trading data, which subset satisfies criteria based at least on one parameter associated with the data.
[0273] It will be understood that columns representative of a parameter of the trading data can be arranged automatically based on criteria defined by a trader.
[0274] Of course, columns representative of a parameter of trading data can be arranged manually through a drag and drop operation of a respective column header by a trader.
[0275] It will also be understood that any icon may be chosen from the group of images consisting of; the logo of the company associated with any security, the trading symbol of the security, the type of security, the quantity of units of the security, the type of order for the security, the status of the order for the security, and combinations thereof.
[0276] In the interactive grid-based graphical quote presentation system of the present invention any cell representing a specific quote may be displayed relative to the price axis, wherein the position of any cell is determined by the difference between the price associated with a specific quote and the price associated with a base price indicator on the price axis. At least one cell representing a specific quote is displayed.
[0277] Differences in the values of the price dimension associated with order data and quote data may be represented through positional distinction, by plotting GUI objects representative of that order data and quote data onto specific positions on the drawing area; and wherein the specific positions are determined by mapping the value of the price dimension against the values associated with the price axis.
[0278] Of course, the trading data may be representative of NASDAQ Level II data.
[0279] Also, any selected security for which trading data is displayed at any instant in time may be changed to another selected security by any trader, at any instant in time. The trading data can be electively filtered to display a subset of the trading data, which subset satisfies criteria based at least on one parameter associated with the trading data.
[0280] It is also possible that the backend trading system maybe market simulation software.
[0281] In the software object of the present invention, differences in the values of the price dimension and the values of the additional dimensions associated with the order data and quote data may be represented through positional distinction, by plotting the GUI objects representative of the order and quote data onto specific positions on the drawing area. The specific positions are determined by mapping the value of the price dimension and the values of the additional dimensions against the values associated with the price axis and the values associated with the at least one additional axis.
[0282] The axis associated with price may be presented as a specific price range above and a specific price range below the last traded price of a selected security or groups of securities at any instant in time.
[0283] The price difference between two adjacent cells along the price axis may be the minimum price variance (MPV), or a multiple of the minimum price variance, for any selected security or groups of securities being displayed at any instant in time.
[0284] Of course, specific order data and specific quote data may be linked and associated to a respective one of a set of GUI objects in the grid-based graphical interface at each trader's location.
[0285] Data communications established over communications channels may be in keeping with selected protocols which are established to standardize data interchange between the grid-based graphical interface communicating over any communications channels with any backend systems; and of course the data communications may electively use secure data encryption modes.
[0286] It will be understood that cells representing a selected quantity of buy orders at or near the bid price, and different cells representing a selected quantity of sell orders at or near the ask price, which represent market trading data being posted by a market participant for a selected security, may be simultaneously displayed.
[0287] In the interactive grid-based graphical trading system of the present invention, a plurality of grid-based graphical interfaces may be presented in a plurality of overlapping tab pages. The tab for any of those pages can be selected, and a plurality of tab pages may be contained in at least one display panel on the display device. The at least one grid-based graphical interface is associated with one tab page or one display panel at any instant in time.
[0288] Of course, the specific visual or graphical properties of any tab page may change at any instant in time, as a result of a specific event occurring.
[0289] If so, the specific event may be triggered by specific market or user defined criteria related to the tab page, or to the securities associated with the tab page.
[0290] Any interactive grid-based graphical trading system in keeping with the present invention may further include software whose purpose is to review and weigh a trader's cash position and portfolio holdings, so as to make a recommendation on an order parameter for a trading order for a selected security, at any instant in time, where the recommendation is a function of an order parameter chosen from the group of order parameters consisting of: the bid price, the bid size, the ask price, the ask size, the last trade price, the volume or contracts traded over an interval of time, the volatility, the liquidity, and combinations thereof, for that selected security at any instant in time.
[0291] The order parameter is at least one of the size of the trading order, the quantity of the trading order, price of trading order, and duration of trading order for the selected security.
[0292] When the graphical display at any trader's location includes a display panel containing data categorized as NASDAQ Level II data for a selected security at any instant in time. The NASDAQ Level II data includes at least one set of data which is chosen from the group consisting; the identity of a market participant whose data is being displayed, the bid price and size associated with a given market participant's data, the ask price and size associated with a market participant's data, and combinations thereof.
[0293] Of course, in the interactive grid-based graphical trading system of the present invention, wherein columns representative of a parameter of trading data can be arranged automatically based on criteria defined by the trader.
[0294] Also, columns representative of a parameter of the trading data can be arranged manually through a drag and drop operation of a respective column header by the trader.
[0295] In the interactive grid-based graphical trading system hereof, a selected tab page associated with a given security may become the active tab page as a result of at least one user interaction associated with that security.
[0296] Also, a tab page is automatically created, at any instant in time, and may be associated with a specific security, as a result of at least one user interaction associated with that security. It will be understood that the created tab page for the specific security does not exist prior to the user interaction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0357] The novel features which are believed to be characteristic of the present invention, as to its structure, organization, use and method of operation, together with further objectives and advantages thereof, will be better understood from the following discussion.
[0358] Turning first to FIGS. 1 and 2, two prior art systems are shown which employ different front ends. In the prior art system of FIG. 1, showing a system architecture which is in place and which is operated by Broker # 1, the system 11 comprises a proprietary front end 12, a proprietary protocol 14, an optional middleware 16, and the backend system 18. The optional middleware 16 and the backend system 18 are located on the premises of Broker # 1, who communicates through a proprietary protocol 14 to the proprietary front end 12.
[0359] In the prior art system of FIG. 2, the system 21 includes a web-based application which presents a web-based front end.
[0360] Communication is carried out through the Internet, as shown at 24. Within the premises of Broker # 2, there is a web server 26, there may be optional middleware 28, and there is a backend system 30.
[0361] Either interactive grid-based graphical trading system 12 or 22 is what a trader will see on his computer, and it is the tool that the trader uses to get quotes, manage his account with the respective brokerage firm, buy and sell shares or securities in general, and to track his transactions. Simple front ends tend to be implemented as web applications, as indicated in FIG. 2; however, any proprietary front end may also be employed. Any of these systems offer satisfactory performance, but proprietary front ends are generally not helpful, when it comes to visualizing market information. Web-based front ends are generally quite slow, because both the user interface and the data must be processed remotely at the web server or at the back end.
[0362] Of course a, system such as that shown in FIG. 2 is easy to deploy, manage, and maintain, if it is web-based because of its centralization at the premises of the respective broker.
[0363] If a proprietary front end is used, that system involves the installation of application software at the local computer employed by the trader. Those systems tend to be somewhat faster and more graphical, and they maybe more interactive than strictly web-based applications, because the application is run locally. Of course, as with any locally installed software which is located at a desktop computer, or even on a small local area network operated by the trader, the software is prone to installation and maintenance problems, file corruption, version conflicts, and upgrade problems.
[0364] If either backend system 18 or 30 exists in conjunction with any embodiment of the present invention, it is because they are the backend systems that are operated by respective brokers, electronic communication networks (ECNs), or even stock exchanges, and the like. Any such backend system may likely reside in a high end UNIX machine. Any backend system will generally have the responsibility for handling a number of tasks.
[0365] They include account management. This is the responsibility for managing and keeping all data up to date for each account--each customer or various accounts run by a customer--that is handled by that market participant. As noted, a market participant might be a broker, it might be an approved electronic communication network, or it might be a stock exchange, commodity exchange, futures exchange, bourse, or auction system.
[0366] Another task charged to the backend systems which function in the prior art, and which function in association with the present invention, is that of processing buy orders and sell orders for each buy transaction and for each sell transaction which that market participant undertakes to perform.
[0367] Still further, the backend system is responsible for order execution, whereby each buy transaction and each sell transaction which the market participant undertakes to perform will be executed.
[0368] The backend system is also responsible for datafeed handling, whereby streaming data concerning any orders or quotes for any selected security is disseminated on request to any trader, as discussed hereafter.
[0369] Finally, any backend system described herein will also be responsible for system management, for purposes of maintaining security and operation of the respective backend system of that market participant.
[0370] A communication protocol is required in prior art systems, as well as in the present system. In the prior art systems, the communication protocol for proprietary front end 12 is one which is used to securely transmit data from a proprietary front end 12 to the backend system 18, and in the reverse direction. Usually, such proprietary protocol is built on top of TCP/IP sockets, most likely using some form of data encryption.
[0371] For prior art systems of the sort shown in FIG. 2, where Internet communication is employed in association with web-based front end, a typical communication protocol is HTTP or HTTPS.
[0372] A middleware component is employed, as shown at 16 and 28 in FIGS. 1 and 2, or as will be shown in FIG. 4 which is discussed hereafter. The purposes for the middleware are discussed hereafter.
[0373] There is appended hereto a Trading Glossary, which is provided so as to assist the reader in understanding certain trading terms, and terms relating to market, in various manifestations. All of the terms mentioned in the appended Trading Glossary are not necessarily employed herein; but when such terms are employed, and their meaning is unclear from the context, then reference should be made to the appended Trading Glossary.
[0374] Also, throughout the discussion which follows, and as shown in many of the Figures of drawings which are described, the names of real securities and of real stock exchanges and other market participants, Electronic Communication Network (ECN) trading systems, and the like, may be noted. The use of such names and identities is not intended to suggest any endorsement or connection with, or position in, any such security, stock exchange, or ECN, by the inventor or anyone associated with him.
[0375] Markets exist to bring buyers and sellers together to efficiently exchange goods and services. In a public marketplace, buyers and sellers make transactions directly or via intermediaries. At a basic level, a market requires the sellers price and terms to sell a given quantity of product. The market participants also need to know the prices that buyers are willing to pay for an item. Often, the price per unit decreases if a larger quantity of product is under negotiation. When the buyers and sellers agree in price and quantity, a transaction or trade can occur.
[0376] In the securities market, the bid price represents the highest price any buyer is willing to pay for a quantity of a security at a given time. The ask price is the lowest price that any seller or dealer is willing to sell a given security or commodity for. When the bid or ask price is in an acceptable range, trading activity in a given security will usually become more active.
[0377] Supply and demand prices vary throughout a trading session and the bid and the ask are typically at differing prices.
[0378] Information about the activity of a market is disseminated (usually in real-time) in electronic format through data feeds. A quote is a type of data feed containing information about the buy and sell prices for the securities traded on the market. Separate data feeds are available for trades, news, and other useful information.
[0379] Buy and sell quotes on marketable products are disseminated in varying detail. In financial markets like the stock markets, basic quote information on securities is readily available over the internet. A basic quote on a security details the last trade price, the bid and ask price, and the change from the previous close. Often, the size of the bid and the ask, the trading day's high price and low price, the volume of the last trade, and the overall session volume is also disclosed.
[0380] A more detailed quote is also available. The detailed quotes disseminated by the NASDAQ stock market are called "NASDAQ Level II", or simply "Level II" quotes. This type of quote is of interest to more active traders, because it allows them to track the activity of market makers that they believe to be price-trend setters. It also allows those with the capability, to buy and sell their posit ions quickly, when it becomes apparent from Level II information that the momentum of the markets has turned against them. With a Level II display, the identity of market makers and ECNs is disclosed and order information on either side of the bid and ask are visible. However, not all exchanges or markets provide order or quote information that allows a trader to view this detailed type of quote for all securities.
[0381] Still more detailed, are market book quotes, which are order and quote information provided by some Electronic Communications Networks (ECNs) such as Island ECN and Archipelago, and stock exchange such as the Toronto Stock Exchange (TSE), which can display buy and sell orders individually listed on the ECN's or an exchange. The market books lists buy and sell orders, the number of shares in each order, and the prices offered. Orders are listed according to price and in time priority, so orders displayed close to the bid and ask on the list will be executed before orders further away in the list.
[0382] Not every quote feed from a stock exchange, stock market, electronic communications network, or quote dissemination service supplies a suitable data feed capable of providing information on the quantity of a security available at each price level during a given instant in time. Exchanges sometimes provide restricted or subscription-based access to similar information, however, some market participants prefer to keep their market book details confidential.
[0383] Depending on the opportunity and technology available, more than one market or network may exist to facilitate trading in a given security or commodity. When more than one market exists for a given product, there is a tendency to link the market information together to compare quote information and trading activity. Technology and computer networks make possible the linkage of the data feed (quotes, trades, news, etc) and order-placement facilities of different markets. As a result of this linkage, bid and ask prices tend to mirror each other, as financial intermediaries such as arbitrageurs trade products between markets when price discrepancies arise.
[0384] There has been a trend in recent years to trade stocks and options in more than one market or exchange. Exchanges like the NYSE and stock markets like NASDAQ have made strategic alliances with overseas exchanges to promote trading activity and facilitate listing active securities in other countries. In the US, options on a given security are often quoted and traded in multiple options exchanges.
[0385] Quote data on securities is often presented in alphanumeric text format. When working with a basic quote, and more than one security is being monitored or traded, the quote data is often displayed in multiple rows and columns of text similar to a spreadsheet. Each row represents a different security, while columns show attributes such as the securities' symbol, bid, ask, last trade price, change from previous closing price, the volume, low price, and high price of the current trading session.
[0386] The text based presentation is often difficult to interpret at a glance. Discerning patterns from the text based quote information of an individual stock or a group of stocks is also difficult. With experience, some traders develop buy and sell "indicators" which assist them in speculating on the direction of a given commodity or security.
[0387] The order placement process in many computer-based trading systems requires the user to interact with a form--which is a collection of graphical elements (e.g. text input area, label, button, etc) through which the user issues commands and/or keys data into the computer system. Once an order is placed, the status of the order and its relation to the market is not always spatially apparent. Similarly, desired changes to the resulting open order also take a forms-based approach, which often increases the time spent on the process as a result of the time necessary to refresh screens and download the revised data. The time taken to place a trade and to change an open order often requires that a trader shift attention to the mechanism of the user interface, rather than to maintain a focus on the market or the security in question, and hence obtain additional beneficial insight.
[0388] For securities, the minimum price variance (MPV) is the minimum amount by which the price of a security can change. The MPV is typically set by the primary marketplace for a given security or product. In investment terminology, the "bid" is the highest price a buyer is willing to pay for an investor's shares, while the "ask" is the lowest price at which a seller will sell shares. The difference between the two is called the spread. A smaller MPV will result in narrower spreads because there are more price points in buying and selling the securities.
[0389] Take, for example, a hypothetical stock with a bid price of 45 1/4 and an ask price of 45 {fraction (5/16)}. The spread between the "bid" and the "ask" is {fraction (1/16)} or 6.25 cents per share. In contrast, when stocks trade in penny increments, the number of price points per dollar is 100, meaning that the bid and ask prices can be closer together.
[0390] A smaller minimum price variance (MPV) will be possible as a result of the US exchanges and stock markets adopting a decimal format. Prior to decimalization, many US equities were traded and quoted at an MPV of {fraction (1/16)} or 6.25 cents, meaning there are sixteen price points or "ticks" per dollar. Option prices over $3.00 have an MPV of 1/8, allowing eight price points per dollar. With decimalization, option prices are expected to trade in 5 cent increments under $3.00, and in 10 cent increments above $3.00.
[0391] It is an intent of the present invention to present quote information for any market in a graphical manner, and hence assist investors and traders in gauging the direction and changes to a security or asset's quote, price, and volume activity over an interval of time. It is also the intent of the present invention to allow traders and investors to view and review quote and order information in aggregate form, or across multiple markets, in an organized and meaningful manner.
[0392] It is also an intent of the present invention to assist traders and investors in selecting the proper quantity of an item to buy and sell, and to graphically place the order to a selected market. It is a further intent of the present invention to execute change orders in a given parameter of an open order in a simple graphical manner that does not distract the trader or investor from the dynamics of the quote display, while monitoring the investment.
[0393] Referring to FIG. 4, some similarities and some differences will be noted with respect to FIGS. 1 and 2.
[0394] In the first instance, the system which is indicated generally at 10, and which is the general architecture for the present invention, includes a front end 32. The front end 32 communicates through a communication network 34 to a market participant 36. Protocol exchanges at 33 and 35 will accommodate internet communications using varying protocols, as is well known. At the premises of the market participant 36, there may be a middleware component 42 installed, as well as that particular market participant's backend trading system 44.
[0395] Thus, the front end 32 may interface with diverse backend trading systems 44. Any market participant 36 may be such as a stock broker, an approved electronic communication network trading system (ECN), a stock exchange, a commodity exchange, a futures exchange, a bourse, or an auction house.
[0396] The ability for the front end 32 to communicate with diverse market participants 36 is possible because of the use of the middleware 42 which facilitates communication between the front end 32, at the PC of any trader or user, and the proprietary backend trading system 44 running on the heavily secured machines of the specific market participant 36.
[0397] As noted, the front end 32 does not communicate with the backend trading system 44 directly, but through middleware 42 if it is present, and also through the communication network 34, as well as interfaces 33 and 35 as may be necessary. The specifications of these interfaces will constitute a standard protocol which is based on eXtensible Markup Language (XML).
[0398] The middleware 42 will translate instructions and data, which are encoded in the standard protocol, and which come from the front end 32 into the native format understood by the actual backend trading system 44. Instructions and data coming from the backend trading system 44 are also converted to the standard protocol by the middleware 42, before it sends them back to the front end 32.
[0399] Thus, the front end 32 is shielded from the peculiarities of a backend trading system 44, which may be different for various market participants, and it allows the front end 32, and particularly the graphical display software and modes which are described hereafter, to be re-used in other applications with minimal modification.
[0400] One important benefit of the middleware 42 is that it enables the market participant 36 to supplement the base functionality of its existing backend trading system 44 with new, value-added functionality. Thus, a set or series of backend operations maybe grouped into "virtual" operation. An example of this is an order amendment transaction, which will be described hereafter. In existing trading systems, an "order amendment" transaction requires that the user go through a two-step procedure: first, the original order is cancelled; then, a new order is issued. With the middleware 42 in place, a single virtual operation--the order amendment operation--can be invoked by a trader. The middleware translates the single virtual operation into the appropriately series of trading instructions require by the back end trading system 44.
[0401] Of course, incorporating a series of operations into a single "virtual" operation is the responsibility of the respective market participant 36, and is transparent to the end user--the user or trader whose location includes a front end 32. The market participant 36 can offer the resulting "virtual" operation to its customers as anew type of transaction, and customers can make use of this new transaction just like any other type of transaction.
[0402] Turning to FIG. 4, the front end has a three-layer logical architecture, consisting of the user interface layer 46, an object layer 48, and a communication layer 50. This design gives the front end 32 the advantage of a clean, organized structure, wherein related software functions are grouped in independent layers, each layer communicating with the others using clearly defined programmatic interfaces.
[0403] The user interface layer 46 contains components that handle the graphics operations of the grid and other graphical objects. These include the construction of the grid (using either an object-based approach, or using a frame-by-frame animation approach); dynamic operations such as moving and highlighting the cells of the grid; and interactive operations like responding to user actions, e.g. adjusting the price intervals on the vertical axis when the user clicks on the appropriate graphical element (e.g. a button). These matters are discussed hereafter, with reference to FIG. 5.
[0404] The object layer 48 groups together components that perform business logic, and components that implement utility functions. The components in this layer: (1) validate users' actions (performed on objects belonging to the user interface layer 46); (2) translate users' actions into commands--if applicable--to be sent to the back-end trading system via the communication layer 50; and (3) process return values, notification messages, or any other data sent by the backend trading system (through the communication layer 50). The object layer 48 serves as an abstraction layer that shields the user interface layer 46 from the implementation of the lower level communication layer 50.
[0405] The communication layer 50 consists of components that act as communication "gateways" between the front end and the backend trading system. This layer essentially translates programmatic requests (which are in the native format of the operating system and application platform of the front end) coming from the object layer. That translation may be into Simple Object Access Protocol (SOAP) messages, but any suitable option for facilitating communication may be chosen. It is to be noted that although SOAP is the primary protocol for front end 32 to middleware 42 communication, other suitable protocols--such as Winsock--can also be employed.
[0406] The communication layer 50 is designed to accommodate the "plug-and-play" addition and removal of communication components, each component implementing a specific type of communication protocol (e.g. Winsock, SOAP) for interfacing with the backend trading system 44.
[0407] It will now be seen that the front end 32 is an important feature of the present invention, as it provides a graphically intuitive, fast, user-friendly application that any trader will use in order to get stock or other security quotes, manage their account with their respective brokerage firm or other market participant, buy and sell securities and stocks, track the status of those transactions, and track their current position vis-a-vis any selected security, their cash position, and so on.
[0408] Typically, the front end 32 operates on a Windows.RTM. platform, but not necessarily. Other platforms may also be employed, including LINUX.RTM., and other proprietary platforms.
[0409] As will be discussed hereafter, the graphical display employs GUI objects to display security data in a dynamic fashion, very intuitively, and allows the trader to buy or sell securities with simple mouse clicks by interacting with the grid-based graphical interface, and by dragging and dropping GUI objects.
[0410] Turning now to FIG. 5, the internal architecture of the front end 32, and the main program therein, is shown in terms of the functional blocks which are operable at the front end 32.
[0411] The front end 32 consists of a main executable program--which acts as the overall "controller" of the front end--and several software building blocks called "components" or "objects". In a Microsoft Windows implementation of the front end, the main program is a Component Object Model (COM)-aware Win32 executable, and the software components are COM components. However, in an implementation of the front end for another operating system and application platform, the actual technologies used may be different, but the architecture will remain the same.
[0412] Unlike some monolithic Windows applications, which put together all functionality in a single package, the front end of the present invention leverages the power, ease of use, and the flexibility of using Microsoft's COM component technology. COM allows the front end to organize functionality into multiple, independent, reusable software building blocks called "components" or "objects". (Note: although there is a difference between these two terms--a component is made up of one or more objects--and the two terms are used interchangeably herein.) Each of these components or objects encapsulates distinct software functionality, and interacts with other components through clearly defined programmatic interfaces.
[0413] The front end 32 is similar to conventional Microsoft Windows applications in that it adheres to the visual (e.g. menu structure, status bars, buttons, etc.) and behavioral (e.g. right-click behavior, resize behavior, etc.) standards for Windows-based applications. Thus, adherence to these standards by the front end of the present invention significantly eases the learning curve associated with mastering the application's features.
[0414] The front end's main executable program controls and manages the lifetimes of the application's various constituent objects--from object creation to object destruction. Furthermore the main program coordinates the operation of the objects, by passing messages between itself and the objects.
[0415] The core of the front end however, is in the set of software objects implementing the bulk of the application's functionality. These software objects fall into two categories: (1) graphical objects, and (2) non-graphical objects. Both types of objects encapsulate software functionality, but the graphical objects also display a visual interface. In Microsoft terminology, these graphical objects are called ActiveX custom controls, while the non-graphical objects are called ActiveX components.
[0416] The software objects are grouped together, according to functionality, into "layers". As noted above, there are three layers: (1) the user interface layer 46, (2) the object layer 48, and (3) the communication layer 50.
[0417] The most important software object is the grid graphical object 52. It displays Level II quotes in a two-dimensional matrix of multi-colored cells, which it constructs dynamically. The grid graphical object receives its data in real-time (or close to real-time) from a quote server (not shown) which resides on the backend 44; the data however, passes through the object layer 48 and the communication layer 50 first. The grid graphical object 52 also implements the graphical placement and modification of orders using a "drag-and-drop" mechanism.
[0418] The grid graphical object is hosted inside a container object 54, to facilitate the easy grouping of multiple instances of the grid graphical object discussed hereafter. The container object 54 is a graphical user interface (GUI) element with the capability to "contain" other graphical objects. An example of a container object is a tab-based dialog object common in Microsoft Windows-based applications.
[0419] The order entry graphical object 56 is a compound object (i.e. object made up of several smaller objects) which users of the front end utilize to post an order (and all its associated parameters). The order entry graphical object 56 is also hosted inside a container object 58.
[0420] The account and holdings graphical object 60 is another compound object that displays summary and detailed information about an account. This information includes the account balance, order status, account summary, etc.
[0421] Each of the three graphical objects described has a counterpart object in the object layer 48. The grid graphical object 52 has a quote source object counterpart 62, which encapsulates the logic necessary for requesting and receiving Level II data from the back-end trading system. The order entry graphical object 56 has an order entry object counterpart 64, which implements the logic and business rules necessary for posting orders to the backend trading system, via the middleware 42. The account and holdings graphical object 60 has an account and holdings object counterpart 66, which implements the logic necessary for requesting, receiving, and updating account information from the back-end trading system.
[0422] The communication layer 50 has one or more objects that implement the logic involved in translating requests and commands coming from the upper layers of the front end 32 into the format expected by the middleware 42. This format conforms to a standard protocol, which is based on XML. The communication objects also translate the data coming from the backend 44, through the middleware 42, into the format expected by the objects in the upper layers of the front end 32. In FIG. 5, there are two communication objects: the Winsock communication object 68, which implements the logic for remote communication using the Winsock protocol, and the SOAP communication object 70, which implements the logic necessary for remote communication using the SOAP protocol.
[0423] Other objects 72, 74, 76 may be found on each of the respective user interface layer 46, object layer 48, and communication layer 50, as may be determined by a skilled programmer who is familiar with the present invention.
[0424] Before turning to a discussion of the graphical display which is presented by the present invention, and as shown in FIGS. 10 to 53, and so as to better understand the purposes and objects of the present invention, its operation, and its functions, several other Figures are presented--FIGS. 6 through 9B and are now discussed in terms of the present invention and the discussion which has gone on before. These discussions are, of course, for purposes of clarity and explanation, and are not intended to be limiting.
[0425] Turning first to FIG. 6, there is shown a representation of the order/transaction processing and order routing subsystems of a prototypical backend trading system. Of course, it will be understood that backend systems are highly proprietary, and thus the components and functionality of the system which is described herein, by way of example only, may not match the components and functionality of actual systems used by market participants.
[0426] The order/transaction processing subsystem 78 receives orders sent from the front end and records them in the transactions database 80. The subsystem applies appropriate business rules to validate the order and the parameters (such as terms) associated with it.
[0427] The order routing subsystem 82 utilizes suitable algorithms and business rules to select the best route for the orders it has received and validated. The best route always directs the order to the market participant (a Market Maker or ECN) with the best execution price.
[0428] If the user of the front end specifies a route for his/her order, the order routing subsystem 82 will use that route to execute the order. However if the user chooses the automatic routing option in the front end, the order routing subsystem 82 will choose the best route for his/her order.
[0429] The order routing subsystem 82 communicates with a local order execution subsystem, (if implemented by the backend) and external trading systems to retrieve and compare execution prices available for an order. The subsystem then uses the price data received to decide where to route orders. The local order execution subsystem is discussed hereafter, with reference to FIG. 8.
[0430] FIG. 7 shows an account management subsystem 84, whose purpose is to handle the creation, monitoring and management of online trading accounts. Before a trader can do online trading transactions, he/she must open an online trading account with an online brokerage firm. There are several types of accounts, depending on the owner of the account (individual or institutional), the purpose for opening the account, and other factors. The account management subsystem 84 manages information pertaining to these accounts and their associated portfolios. It also handles password authentication during the initial login phase.
[0431] The account management subsystem 84 consists of three modules: (1) a login verification module 86, which handles authentication of users logging in to the backend system; (2) an account creation & maintenance module 88, which handles the creation, deletion, and management of online trading accounts; and (3) a portfolio management module 90, which handles the portfolios associated with the accounts managed by the account creation & management module 88.
[0432] FIG. 8 is a representation of an optional order execution subsystem 92 of a prototypical backend trading system. For Electronic Communications Networks (ECNs), an order execution subsystem 92 is a requisite component, but not for online brokerage firms, which delegate their order execution services to external trading systems.
[0433] The order execution subsystem 92 consists of two modules: an order execution module 94 and a trade reporting module 96.
[0434] The order execution module 94 handles the automated matching of orders entered in an order book 98. It uses appropriate business rules and matching algorithms to give orders the best price possible at the time of execution. It also implements logic for handling orders with associated special parameters like all or none orders, date/time-dependent orders, etc. This module also handles the cancellation of previously entered orders.
[0435] The trade reporting module 96 manages the historical database of all trades executed by the order execution module 94. This module handles requests coming from the other subsystems for trade and execution information.
[0436] With reference to FIG. 9, a prototypical backend trading system is shown by its functional blocks.
[0437] It will be recalled from discussion above with reference to FIG. 4, for example, that the front end 32 is capable of interfacing with diverse backend trading systems 44. This includes any system that can: (1) manage online trading accounts, (2) publish quotes (3) receive orders, (4) execute orders, and (5) provide feedback to the trader on the status of his/her orders. The middleware 42, makes this capability possible.
[0438] Although the backend trading system 44 can be any of the following: an auction system, a currency trading system, or a commodity trading system; the present invention is particularly directed towards securities trading. Thus, this description focuses on a specific type of backend trading system 44. The many similarities between a securities trading system and the other backend trading systems mentioned allow the present invention to be ported from one backend trading system to another, with relative ease.
[0439] This discussion with reference to FIG. 9 defines, in general terms, what a prototypical "backend trading system" is--its architecture, the processes involved within the system, and the data that is passed back and forth between the front end 32 and the backend trading system 44.
[0440] A backend securities trading system 44 is a computerized system operated either by an online brokerage firm or an Electronic Communications Network (ECN). It typically consists of the following subsystems: (1) account management subsystem 91, (2) quote publishing subsystem 93, (3) order/transaction processing subsystem 95, (4) order routing subsystem 97, and (5) order execution subsystem 99.
[0441] Furthermore, the implementation of the backend trading system also depends on the type of company that runs it. Online brokerage firms usually implement components 91, 93,95, 97, but not 99; ECNs on the other hand implement all five components. All backend trading systems 44 however, ultimately link up with a stock market's or stock exchange's computerized trading system.
[0442] The account management subsystem 91 handles the creation, maintenance and monitoring of online trading accounts. It stores and manages information on the account's owner, its privileges, limitations, balance, its portfolio, and other related information. The account management subsystem 91 also handles the validation of user passwords when users initially log in to the back-end trading system.
[0443] The quote publishing subsystem 91, (which may also be referred to as a stock quote server) broadcasts quotes to subscribers. There are two types of quotes: a basic quote which contain information on a stock's last price, the current bid and offer price for the stock, the change in price from the last trade, opening and closing price, highest and lowest price (for the current trading day), and the volume of stocks traded; the other type of quote is the detailed quote, which contains a listing of the prices quoted by different market participants. The detailed quote can also be categorized into two types: one is the detailed quote that comes direct from a stock market like NASDAQ, whose implementation of the detailed quote is called "Level II". NASDAQ Level II is a tabulation of the bid and offer prices quoted by NASDAQ Market Makers and ECNs. The other type of detailed quote comes from ECNs or stock exchanges and contains a snapshot of their market books (the queue containing all individual orders submitted to the ECN by its customers, the entries of which are ordered/arranged according to certain business rules).
[0444] The order/transaction processing subsystem 95 receives and validates orders coming from the broker's customers. After validating an order, it applies appropriate business rules (which vary depending on the broker) to the order. These business rules may include, among others, checking the account status of the owner of the order, checking the type and terms associated with the order, etc. Finally, the order/transaction processing subsystem 95 closely coordinates with the order routing subsystem 97 in deciding whether to register or "enter" the order into the local market book 98 (if the back-end trading system has it), or to route it to an external trading system, e.g. NASDAQ or an ECN.
[0445] The order routing subsystem 97 uses appropriate business rules and algorithms to select the optimal route for orders accepted and validated by the order/transaction processing subsystem 95. The optimal route directs the order to the best order execution system--the one with the best price, whether it be local (if the backend trading system implements an order execution subsystem 99) or remote (if the backend trading system does not implement an order execution subsystem 99, or it is not the optimal one).
[0446] The order execution subsystem 99 matches buy orders with corresponding sell orders. It continuously examines entries in the local order book 98, and then applies certain algorithms and business rules to decide which "buy" orders it will match against corresponding "sell" orders. This subsystem is tightly linked with the order routing subsystem because the National Association of Security Dealers (NASD) rules dictate that backend trading systems 44 must find the best price possible for all orders it accepts. This subsystem is implemented only by ECNs. Online brokerage firms typically delegate their order execution services to an external trading system like an ECN, or to a NASDAQ Market Maker.
[0447] As noted, a particular purpose of the present invention is to provide a graphical user interface which may be used by any trader. Typical graphical displays are discussed with respect to screen snap shots shown in FIGS. 10 and 53, described hereafter.
[0448] The front end software of the present invention comprises the grid graphical object, several display panels, and several GUI objects. The most important component of the front end software is the grid graphical object.
[0449] Thus, a principal function of the GUI front end is to provide a grid representation of market conditions with respect to any security or group of securities, as discussed hereafter, effectively in real-time. The GUI front end also provides a number of display panels and GUI objects for dynamically displaying trading data, and updating the trading data being displayed. A plurality of grids may be shown, as noted hereafter, in side-by-side arrangement, as well as in tabs where once grid is hidden behind another in typical fashion well known particularly to programmers and users of Windows software.
[0450] A typical grid is shown in FIG. 10. Here, data for a plurality of market makers are shown in columns 100a . . . 100g (being understood, of course, that the number of columns may vary as may be elected by the user, or as dictated by the software, all as described hereafter). A price axis is shown at 102; in this case, the prices are shown varying in one unit intervals (typically, one cent intervals). Of the tabs 104a . . . 104d, each is indicative of a separate grid for a separate security. Tab 104a has been chosen, so that data concerning a hypothetical security identified as XYZ Corp. is shown. Its stock market symbol is shown at 106. In a grouping of displayed boxes shown generally at 108, specific data is shown concerning the hypothetical corporation. In particular, the price of the last trade at 56.92 is shown, being up 0.18 or 0.32%. The current bid price for this security is 56.90, and the current ask price is 56.94. The highest trade for the particular trading session in progress was at 56.56; the lowest trade was at 56.10.
[0451] The last trade was for 200 shares; and there have been 1,123 trades during the current trading session in progress, for a volume of 8,655,000 shares. The bid size and ask size boxes indicate the number of lots (each being 100 shares) being offered for purchase, or the number of lots being offered for sale, respectively, at the current bid and ask prices.
[0452] Another box labelled PG is shown at 110, and is described hereafter.
[0453] What is important to note is that there are a number of rows or price bins which are shown at various prices, and across various columns. It is important to note that in FIG. 10, and throughout all of the Figures being discussed herein, active or selected cells for various market makers or other criteria as may be determined for each column, at various prices as shown in the rows thereof, are indicative of either buy or sell quotes or orders. The bid prices--that is to say, each buy order or quote from any market participant which is being tracked on the grid, is at a specific price. As noted hereafter, there may be more than one buy order or quote at the same price, for any one market participant or market maker. In any event, all of the buy order or quote prices are shown with a particular hatching in the Figures--upwards to the right. That hatching is indicative of a specific color when the grid is, in fact, shown on the computer screen of a trader, the color being at the election of that trader.
[0454] The ask prices are shown with a different hatching--upward to the left--and of course it will be understood that such hatching is indicative of another color which is mutually distinctive from the first color used for bid prices.
[0455] Any of columns 100a . . . 100g can be moved to a different location by selecting the column header and dragging it. They may also be automatically arranged according to some particular criterion, such as the most active market. Other columnar data, particularly aggregate data, are described hereafter.
[0456] Box 106 permits entry of a symbol for any given security, after which the button 112 is clicked.
[0457] It is possible to adapt the grid display shown in FIG. 10 (and others) for use on Personal Digital Assistant devices or other portable platforms which are capable of displaying graphical information in keeping with the requirements of the present invention.
[0458] Buttons may be provided to zoom in or out on the price axis 102; a status bar is shown at 114, and a close button is shown at 116.
[0459] FIG. 11 is similar to that of FIG. 10, showing somewhat different data, because the price axis 102 shows each price bin separated from adjacent price bins by increments of 0.05. Thus, while the price range shown in FIG. 10 is from 56.73 up to 57.04, the price range shown in FIG. 11 for the same security is from 56.00 to 57.55.
[0460] It will be noted that each price bin or cell in column 100a in FIG. 11 is filled. That is because there is at least one bid or ask offering within each increment shown on the price axis in FIG. 11. For example, while there is no activity shown at prices 56.90 up to 56.93 on the price axis 102 shown in FIG. 10, there is activity shown at 56.94 and 56.95, and thus there is ask activity shown in the price bin at 56.95 in column 100a as shown in FIG. 11. On particularly active days, market volatility may require that the trader sees a wider price range than prices that are merely separated by the security's MPV (minimum price variance). In FIG. 10, the price for XYZ Corp. may vary in one unit intervals; thus, each price bin shown in FIG. 11 may hold a multiple of the security's MPV.
[0461] The details of the dynamic changes are discussed hereafter, with reference to FIG. 53.
[0462] A replay button 118 is indicated in FIG. 11. This replay button can activate an historical data animation which will be displayed graphically on the grid, as described hereafter. Thus, quote and order information for a particular time interval can be reviewed, and accelerated if desired. The replay button 118 will speed up activity so as to gauge the market direction or momentum more accurately. It will allow a trade to compare activity from one period to another; and it will also permit a trader to review market activity that was missed.
[0463] FIG. 12 shows a typical screen shot having a number of specific display panels down the left hand side and across the bottom, together with two grids 120 and 124, which replicate data shown in FIGS. 10 and 42, respectively. FIG. 13 shows three grids 120, 122, 124 which replicate the data shown in FIGS. 10, 11, and 42, respectively.
[0464] Also shown in FIG. 12 are a number of other tab sets 126, 128, 130, and 132. There is also a Position Guide box 134 shown in FIG. 12.
[0465] It will be noted that tab set 128 is also shown in FIG. 13, but in a different location than in FIG. 12.
[0466] The various tab sets permit the trade to set up and enter orders, monitor open orders, view filled orders, view market statistics, monitor a cash position, recommend shares to purchase, interact with other traders, and follow market developments, all as described hereafter.
[0467] Of course, tabs can be moved within tab sets and between tab sets; and may be renamed. Also, as is known in a Windows environment, tab pages can be positioned at any coordinate on the screen, and may dock and undock with other windows, in keeping with Microsoft Windows conventions.
[0468] The Position Guide 134 will recommend a suitable level of shares to buy or sell, according to factors such as cash on hand and portfolio value, as described hereafter. A NASDAQ Level II grid 124 is shown, as described hereafter with respect to FIG. 42.
[0469] Obviously, the overall look and feel of the user interface may be controlled by a user preference configuration capability. Accordingly, the number of grids that are displayed, the maximum number of windows, the color and design or applications in, as well as other parameters which are relevant to the overall look and feel of the application can be selected, according to the user's preferences and experience.
[0470] A holdings tab from tab set 132 is shown in greater detail in FIGS. 14 and 15. In FIG. 14, the data is shown in tabular manner; in FIG. 15, it is shown with separate icons for each holding.
[0471] The significance is that an icon under the symbols column 136 in the tabular format of FIG. 14 can be dragged into its associated grid for a sale or so as to be covered. Likewise, any of the icons shown in FIG. 15 can be dragged and dropped onto the respective grid.
[0472] Examination of FIG. 14 shows that 500 shares of XYZ Corporation are owned; that they were purchased at 56.26 and that the current price is 56.92, up 0.66, for a profit of 330.00. Dollars are shown, but other units might easily be used as well.
[0473] From FIG. 15, similar data is shown, but in somewhat less detail.
[0474] On the other hand, the icons shown in FIG. 15 may be colored so as to show the type of security or type of order that exists. For example, colors may be used to represent a short order, another color used to represent an option, or a margin purchase, or to indicate profit or loss on individual positions. Each icon may further have data associated with it, which would be revealed by holding a cursor over the icon. The status bar 138 may also display the data, as well as the current market price for the security, if elected.
[0475] FIG. 16 illustrates a market order entry tab 127, chosen from tab set 128. This is a form based representation; and it will be noted that there are buy, sell, and short buttons 140, 142, 144, respectively, which can be pressed so as to route an order to a given market. That market may be as shown at 146. Similarly, as can be particularly seen from FIGS. 12 and 13, a buy, sell, or short button 140, 142, or 144 can be dragged onto the grid 120, for example, for the order to be routed to the selected market--in this case, ISLD.
[0476] A similar tab is shown in FIG. 17, also selected from the tab set 128; but in this case, it is the limit order tab 148 which has been selected. A further button, the terms button 150, is shown under the tab 148, which permits the trader to specify order execution terms.
[0477] Another tab, tab 152 from the tab set 128, is shown in FIG. 18. That is the stops tab or stop order entry tab.
[0478] This stops tab 152 has similar properties to that of tab 148, except that it is equipped with four other buttons 154, 156, 158, 160 which are labeled as stop buy, stop buy limit, stop loss, and stop loss limit buttons, respectively. An order input can be in terms of shares or an order reference number, so that a filled order can have a corresponding stop order associated with it. Stop orders trigger when a lot has traded at the stop price. When a stop limit order has been entered, a distinction may be shown between the limit price and the stop price, on the respective grid display.
[0479] Yet another tab in the tab set 128 is a change order tab 162, shown in FIG. 19. This tab is employed so as to change the parameters of an open order B that is, an order that has already been placed. Here, the order reference number 166 is shown, so as to identify the order which is already in place. The new shares and new price are shown at 168 and 170, with the submit button 172 effecting the change order. Terms maybe set by employing button 174.
[0480] Changes may be made, of course, in respect of the volume or the price, or even the route through which the order will be placed.
[0481] FIG. 20, shows another tab from the tab set 132, namely the open tab 176. FIG. 21 shows similar data, except in icon form; and FIG. 22 shows the same data from FIG. 21 with a further drop-down right click menu.
[0482] As described above with respect to FIGS. 14 and 15, there is in this case a change column 178 shown in FIG. 20, which permits order parameters to be changed and which allows the order and the underlying security to be displayed on the grid of FIGS. 10 or 11, for example. The change box can be dragged onto the grid to a specific price bin, so as to effect a price change or to submit an order to a different market.
[0483] Again, different colors may be employed to show the type of order buy, sell, short, etc.
[0484] The same data is shown in FIG. 21, but in icon form.
[0485] Referring to FIG. 22, the status bar 180 indicates that there are six open orders; and in this case, a right click on icon 182 has opened a drop-down menu 184, which menu permits open order parameters and terms to be changed or cancelled.
[0486] Referring to FIG. 23, another tab 186 from the tab set 132 is shown. This tab 186 reveals data concerning orders that have been filled. Such orders may have been buy, sell, or short--see, for example, FIG. 20--and the data provided in FIG. 23 shows the price and time, and quantity, at which the order was filled or at least partially filled.
[0487] FIG. 24 shows further detail from the tab set 130, in this case being details concerning option orders or other derivatives that may have been placed. Thus, such option orders or other derivatives have their own dedicated order entry tab, with all of the necessary information being entered such as at 190 where a derivative being bought, has additional criteria being chosen as indicated. The submit button 192 will effect the transaction.
[0488] Obviously, the submit button 192 may be dragged to a suitable grid so as to enter the order, as will be evident from a review of FIG. 12, for example.
[0489] A further drop-down menu may be provided so as to select different market participants, for routing of the specific transaction being effected.
[0490] Turning now to a discussion of FIGS. 25 and 26, a typical representation is shown in the case of a falling market.
[0491] It will be noted that FIG. 25 is similar to FIG. 10. However, in FIG. 25, the price of XYZ Corp. has dropped from 56.92 to 56.79. As a result, the security is trading down some 13 rows from 56.92. The last trade of 56.79 is highlighted on the price axis 102. The bid and ask of the market participants have fallen to the lower portion of the grid 120, since the price axis is fixed for the 0.01 row increment. If the security trades at or below 56.73, the lowest visible row, the price axis 102 will adjust the displayed price range down to maintain the trading activity in the visible portion of the grid.
[0492] The price axis 102 may adjust to trading activity automatically or manually. In automatic mode, it will maintain trading activity substantially centered in the middle of the grid by adjusting the displayed price range of the price axis continuously. A smoothing function may be used to prevent the price axis from adjusting itself to quickly in an active market. In manual mode, the user resets the trading activity to the center of the axis 102. A buy order cell--such as cell 200 on FIG. 28--on a fixed price axis 102 will remain stationary as the trading activity moves towards it and eventually fills the order.
[0493] When a security is first shown on the grid 120, the user may elect to position the price axis 102 according to the session high, low, opening, or last trade prices. Alternatively, the price axis 102 can be centered to the closing price of the previous session, or a technical indicator such as the 50 day moving average.
[0494] FIG. 26 is similar to FIG. 25, except that the price axis 102 has been centered on the grid 120. A buy order cell 200 on FIG. 28 on a centered price axis will appear to climb higher towards the trading activity as the price of the security falls, until eventually the order is filled. A right click menu on the price axis 102 can select how the price axis reacts to price variations in the security.
[0495] Turning now to FIG. 27, there is shown a grid representation in which an aggregate price column of an option series is illustrated. Here, the grid 196 shows an option series representation for a particular call option of an option eligible index.
[0496] In this case, the price axis 102 is in 0.05 increments as is suitable for an option priced under 3.00. There is also an aggregate column 198 which displays the aggregate quote from one or more market participants with all available buyer and seller prices and combined order size. Orders placed in the aggregate column may be routed automatically to the market that contains the best price or fastest executions.
[0497] Some users may not be interested in viewing quote activity for individual market participants, as shown in columns 100a . . . 100e, and may choose to view and enter orders only in the aggregate column 198. Options symbol are entered into the grid 198 directly, or via the options entry tab 188 (see FIG. 24).
[0498] Turning now to FIG. 28, a representation of a limit buy order is shown. The data shown on the grid 120 of FIG. 28 are the same as those shown in FIG. 10.
[0499] FIG. 28 demonstrates how a buy order 200 is located on the grid 120. The buy order for 200 shares of XYZC is a limit order placed at 56.88. This is 0.04 below the last trade price on XYZC, as shown at 202. The market where the order is placed is Island ECN, as noted in the header for column 100a. To distinguish an order from the background quotes, a contrasting texture or color is used. The text inside the order also helps identify the type of order and shares being sold. In a similar manner, a limit sell order may be placed in a suitable market and in the upper portion of the grid representing seller quotes.
[0500] The order is placed on the grid 120 in a number of ways. First, the order will be entered automatically into a suitable grid if it is submitted from an order entry tab such as that shown in FIG. 17. Second, the order can be entered by dragging and dropping from the Position Guide 134, which recommends the amount of shares to purchase as well. Third, the order can be dragged and dropped from the holdings tab, as seen in FIGS. 14 and 15, or a similar status tab.
[0501] The orders can be posted to the grid direct from the appropriate entry method, either through the order entry tabs or the Position Guide, with validation to follow; or the orders can be posted after validation from the ex change or market. In the latter case, a delay may occur between the time the order is entered and the time it is validated. In this case, the cell 200 may indicate a non-valid status until the backend system validates the order.
[0502] FIG. 29 is similar to FIG. 28, except in this case the order 200 has been routed from one market to a different market at a different price. The original order has been routed to Archipelago ECN in column 100b, and the buy price has been reduced to 56.83. This apparent order change occurs when a selected buy cell 200 is dragged or routed by the computer's pointing device, such as a mouse or a keyboard cursor arrow, such that the selected buy order cell 200 moves left, right, up, or down, along the grid. The practical effect, from an exchange or market makers perspective, may be to cancel one order, and enter another in a different market, or to change (CFO) one open order to reflect an adjusted price, volume, or other order parameters or terms. This routing of orders between markets, and changing prices graphically, is at the heart of the grid's function.
[0503] FIG. 30 is similar to FIG. 10. However, in FIG. 30, only the bid and ask for each market participant is displayed. The buy order 200 from FIG. 29 remains visible. Some users may prefer this view, selected from the grid preferences menu, as it removes movement outside the market and makes open orders stand out.
[0504] FIG. 30 also shows an example of a mouse over effect showing a price axis popup box 202, a quote or order popup box 200, and a market participant popup box 206, so as to result in the display of other relevant information At the top of this view, a radio button 208,210 shows that the tab page can toggle between a grid display of XYZC and a chart of the security.
[0505] FIG. 31 shows a stop loss limit order 208 and 210. In this example, the stop price is 56.82. When one lot of the security has traded at or below the stop price, the associated limit selt order 210 becomes active. Both parameters, the stop price, and the limit sell price, can be changed by dragging its associated cell. Text inside the order cells help identify the order type, quantity, and function.
[0506] FIG. 32 is a representation of FIG. 31, once the stop price has been reached and triggered. In this view, the stop price 208 of 56.82 remains on the grid 120 to show that the stop price has been triggered and the limit sell order 210 is now an open order. The limit price may be changed while the order is open. In this manner, more complex order types may be displayed.
[0507] Referring no to FIG. 3, similar data to that which is shown on FIGS. 28, 29, and 31, is shown. However, in this case, an integrated icon area 301 is included at the right of the grid, showing the status of orders or holdings that are related to XYZ Corporation. The icon area 301 may be considered to be a parking area, in that orders are parked in order that the trader may drag them onto or off the grid 303. One advantage of the icon area 301 is that an order can be dragged off the grid 303, even though the grid may have been cancelled, and held in the icon area 301 so that it can be dragged back onto the grid later as a new order, without having to set up the trade all over again.
[0508] A further feature of the icon area 301 is that multiple orders with respect to the same security may be established. Here, it is seen that there is an intention to buy 200 shares of XYZ Corporation at 56.88, shown at cell 200 just as it is shown in FIG. 28. There is also an intent to sell 500 shares of XYZ Corporation through market participant MM2, at 56.98, as shown at cell 305. The status of those cells 200 and 305 are shown at icons 307 and 309, respectively, in the integrated icon area 301. However, it will also be noted that icon 311 shows that previously there were 500 shares of XYZ Corporation purchased at 56.26.
[0509] An advantage of the integrated icon area 301 is that icons relative to the specific security may be displayed, whereas the holdings tab as seen in FIGS. 14 and 15 contains information as to all securities which are under consideration. Thus, using a display set up as shown in FIG. 3, the trader can concentrate on a single security, if that is the trader's wish.
[0510] FIG. 33 is somewhat similar to FIG. 27, and in this case it shows a grid 212 for a security, XYZ Corp., which trades in multiple markets, being represented by an aggregate column 214. The aggregate column combines quotes and order data from multiple market participants 100a . . . 100f into a single column. The aggregate column 214 mayrepresent, for example, aggregate quote data from those market participants available to the trader's brokerage firm to trade on and to submit orders to. The grid's price axis 102 may also be split into two price series to show different price ranges for the same security.
[0511] FIG. 34 is a representation of FIG. 33, having the same data, but with each cell which contains a market quote having a text display of a cell property--in this case, the text label refers to the total lot size of the cell. A drop down menu 216 is presented at the top of the page tab for selecting the property. In the preferred embodiment, the text shown on each cell can be total lot size, number of orders, dollar value, share quantity open or share quantity traded inside the cell. Similarly, the total lot size, orders, trade value, or share quantity filled or executed at each cell can be shown over a period of time. In the latter case, the length of time specified may be from the beginning of the current session, during the past hour, or a user selected time interval. The aggregate column 214 may also contain text summary data. In addition to a text inside the cell, colors and color gradients can be used to display the same parameter or an alternative parameter of each cell or order.
[0512] Turning now to FIG. 35, a grid 220 is shown, which uses the concept of the aggregate column 214 to show a one column view of one or more market participants. The remaining columns 222 and 224 are used to show lot size and order quantity for each price increment. A graphical representation of lot size and order quantity is shown next to the text data, at 226 and 228, respectively. A replay button 118 is shown, which can animate historical data in a graphical presentation. A right click menu is available over the column name to allow the user to select a data display from specific markets rather than an aggregate representation. For example, the grid column 214 can represent data only from Island ECN and display the corresponding text 222, 224 and graphical representation 226, 228 of lot size and order quantity, respectively.
[0513] FIG. 36 shows the market column or aggregate column 214 of FIG. 35 rotated 90 degrees, and now presented horizontally at 230. Price increments run along the x-axis from left to right. The rightmost cell contains the highest price value. The size of each price bin may be increased to view a larger price range for the security. Direction buttons at each end of the grid allow the grid's price axis 230 to be scrolled left or right. The cell values at the endpoints 232, 234, the bid and ask 236 and 238, and the last trade 240, are all indicated and linked to their representative cell. Open orders are also shown, in this case at 242, above the grid.
[0514] A Position Guide 134 allows orders to be dragged and dropped onto any cell that is displayed. In this type of display, the bid is shown on the left, and the ask is shown on the right. There is less room to display text inside each cell in this implementation of the grid 220. As a result, buy orders 242, the last trade 240, or a sell order, may be represented by the single letters "A", "L", and "S" within each cell. These cell types may also be represented by specific colors as well.
[0515] Under the grid 220, a chat application 244 allows discussion of a selected security or topic. The integration of the chat application on 244 the same tab page allows a security to be monitored closely while a discussion is ongoing.
[0516] FIG. 37 shows a single column representation of a grid 246. Single column representations are appropriate whenever listed securities trade and are quoted in only one market such as the Toronto Stock Exchange. Those quotes are shown in column 248. The remaining space on the tab page is taken up by charts 250, 252 and a fundamental profile data 254 on the security. A drop down menu allows the chart type and time interval to be selected.
[0517] FIG. 38 is similar to FIG. 28, with a representation of a right click menu 254 on the buy order. The right-click menu 254 is location and context sensitive, and allows the user to view order statistics, change order parameters, adjust price bin size, set preferences, display an aggregate column, and undo a change. The right-click menu 254 also allows the user to access the Position Guide 134 and the replay feature 118 of the grid interface.
[0518] FIG. 39 is a representation of the replay settings tab 256. The replay feature 118 provides a graphical payback of historical data and trading activity on a grid. If the historical time interval being reviewed is large, the playback speed can be accelerated. For example, if the historical interval being reviewed was originally 60 minutes long, as can be seen by comparing the times for the start and end of the interval to be displayed, as set at 258 and 260, the user can adjust the playback time period to view this interval at 10 times normal speed which would result in the animation lasting six minutes. Similarly, the animation interval can be fixed for a defined time, for example, 2 minutes, without regard to how long the original historical time interval was. If the historical data or necessary file on the security is not resident on the user's computer, it may be downloaded from a suitable server. The replay application 118 uses actual historical quote data to run the animation. The replay feature 118 works only if there is available archived (historical) quote and order data from the user's computer or from any suitable server. The user can elect to store historical data locally through the record function, which will store data on the user's computer's storage means.
[0519] FIG. 40 is a representation of the Position Guide 134 settings. The Position Guide 134 recommends a quantity of each security to buy or short, based on input from the user on the amount of funds to be invested in each type of security, and the percentage of buying power or portfolio value available to be invested in any trade. Recommendations are rounded up or down to a standard lot size or contract size, as shown at 262. The recommended quantity to be purchased or shorted can be dragged and dropped from the Position Guide 134 (see FIG. 36) to any cell on the grid, for the corresponding security. The Position Guide is made available directly on the tab page of each grid by electing to show the Position Guide 134 on each tab page.
[0520] Advanced settings 264 on the Position Guide tab 134 give access to timing tools so that trades that appear technically sound bias the Position Guide to recommend a higher quantity of the security than trades that appear to have poor or no technical merit. The Position Guide allows the trader to enter limit orders with one or more parameters based on the Position Guide's recommendations.
[0521] FIG. 41 shows horizontal grids 270, 272, 274 for three securities. Each security has its own grid 278,280 and Position Guide 134a, 134b, 134c, respectively. The top security, XYZ Corp, has two grid rows 276a, 276b associated with it. Each functions independently and provides a display of the security in its own respective price range. Orders 278 to sell at 57.50, 280 to buy at 56.88, ask information, and last trade information 284 can be indicated on both related grids if the price labels overlap. Each grid allows the price bin to be adjusted independently of the other.
[0522] The middle security is an option series. The Position Guide 134b recommendation is based on contracts, not shares. Options above 3.00 trade in MPV of 0.10 increments. There is a sell order 286 at 8.10.
[0523] The bottom security, ABCD Corp, is being monitored by the user, and has no open orders associated with it.
[0524] Turning now to FIG. 42, there is shown conventional NASDAQ Level II display 124, as used by day traders in the US equity markets. Time and sales information is on the right side of the display at 290. Since, the grid representation of trading and quote activity differs from the NASDAQ Level II view, traders new to the grid view may prefer to additionally monitor securities with NASDAQ Level II displays. To accommodate this need, the tab pages of the grid area can switch between NASDAQ Level II views and grid-based views of the trading activity.
[0525] FIG. 43 shows a representation of the special terms setting dialog box 300. Special terms dictate how the order must be filled. Setting special terms is a common feature of trading applications. Special terms for an open order may be accessed and changed from the right-click menu of an order cell on any grid, as shown at 254 in FIG. 38.
[0526] FIG. 44 shows a representation of an option chain on a grid 302. The tab name OEY*D, shown at 304, indicates an option chain. The grid arranges the data associated with the option chain to provide a representative display. There are two grids 306, 308, each with their associated price axis 310, 312, respectively. Bid and Ask prices are displayed for various months, in columns 314a . . . 314f at different price levels. Two buy orders 316,318 are indicated. The first is to buy 10 contracts of the OEX April 620 calls at 1.30. The second to buy 5 contracts of the OEX July 620 calls at 2.05.
[0527] The grid drop down menu 318 allows data for puts, call, or both classes to be displayed. An order status area 320 allows the user to monitor the status of the open options orders. The option order prices can be changed, by dragging the order cell up or down its respective column. The radio buttons 320, 322 allow the option quote data to be displayed in a table style view, or on the grid. Standard preferences may be applied such as showing contract size in each cell, as a text label. Options data may be filtered to display only the bid and ask of each month to reduce the level of detail. Visual and auditory alarms or notifications can be set to warn the user of a change of status or trading activity.
[0528] Each column contains aggregate data combined from all available markets. However, a single market, such as the CBOE, maybe viewed on the grid as well.
[0529] FIG. 45 shows an alternative representation of the option chain of FIG. 44. Both Puts 324 and Calls 326 are displayed in this view. The selection of which class to display is via the put and call check boxes 328, 330 under the grid display radio button 322. The price axes 332, 334 are independent of each other, to optimize the display of relevant quote and order data.
[0530] Changes can be made to the initial layout of the option chain. For example, the month displayed in each put and call column is via a right-click selection on the column name, as shown at 336.
[0531] FIG. 46 shows yet another alternative representation of the option chain of FIG. 44. Both Puts and Calls are displayed in this view at 340 and 342, respectively. Each column 344a . . . 344f represents a different strike price for the month of April. Two limit buy orders 350,352 are indicated: the first is for 10 contracts of the OEX April 615 calls at 1.55; the second buy order is for 5 contracts of the OEX April 585 puts at 3.30. The price axes 354, 356 for each class are independent of each other. A right-click on the column heading allows the strike price to be changed, as shown at 360.
[0532] FIG. 47 is a representation of an aggregate column 362 of quote data and a corresponding NASDAQ Level II type display 364. Orders are entered or adjusted on the column according to market developments reflected in the Level II display. Although one column 362 is displayed to represent the aggregate data, the user may elect to show a second column to monitor a preferred market maker, exchange, ECN, market participant as referred to herein.
[0533] The radio buttons 366,368,370 on the Figure allow the trader to alternate views from a multiple column grid, to a split grid and Level II view, and to a grid and Chart view. A further view may include a grid and a chat discussion on the security, or news updates.
[0534] Turning now to FIG. 48, there is shown a consolidated view 380 of all open orders in a user's account. To obtain this view, the front end system 32 determines whether each open order is on the bid side or the ask side of the underlying security. Then, the front end system 32 plots the relative distance of each order from the security's bid or ask price. The price difference between the bid or ask price and the open limit order is plotted on a common grid and a relative price axis. It results in a cluster of orders around the normalized bid and ask reference points.
[0535] For example, GE in column 382a at 384 is an open limit order to buy one lot. The value on the price axis 386 is -0.20, which means that the user's buy order is about 0.20 away from the current bid of GE. If the bin increment was 0.01 instead of 0.05, a more exact calculation of the price gap would be possible. Orders can be dragged and dropped closer or further away from the trading activity, which will effect a change in the price of an open order. If an order is dragged to the opposite side of the market, the system assumes the order has changed to a market order and informs the backend accordingly.
[0536] There are two purposes for the columns 382a . . . 382e. The first is to allow multiple orders to overlap at a given price point or price bin. The left to right placement of orders when multiple orders reside in one bin, is determined by the orders closest to the bid or ask price. These orders are placed on the leftmost column. A second ranking variable may be the value of the trade, or the time interval since the order was submitted.
[0537] The second purpose for the columns 382a . . . 382e, is to allow open orders to be dragged left or right, away from the main cluster of orders so individual stocks or groups of stocks can be segregated and monitored in relation to the central order cluster. For example, semiconductor sector stocks such as INTC (386), AMD (388), and MU (390) may be dragged along the row to the right edge of the grid so the relative performance of those open orders may be monitored for signs of a deteriorating market or an upcoming rally.
[0538] The first column 414 contains two user-defined buttons 392, 394 in each cell. In this instance, the buttons are a cancel button, CXL, and a change limit order to market button, MKT, respectively. Pressing either button changes all orders in the relevant row to the designated command.
[0539] At the top of the tab page is a column of five larger buttons 400, 402, 404, 406, and 408. When a market event such as a Federal Reserve Board meeting produces breaking news, the user can elect to cancel all open orders at 400, cancel all open buy orders at 402 or open sell orders at 404; or change all open limit buy and limit sell orders, at 406 and 408, respectively, to market orders. Major market moves may be determined by monitoring a defined group of indexes and stocks on the upper portion of the grid, at 410.
[0540] When a pointing device such as a mouse is used to select an order cell, the last price, change, and percentage change are displayed above the grid. The security headings 410 are user selectable. In FIG. 48, the stock selected is Microsoft, and its quote data is visible below the value for the Russell 2000 Index at 412.
[0541] Each order may be cancelled or have its terms changed by a right click on the selected order cell and choosing the command from the resulting menu.
[0542] FIG. 49 shows an alternative representation of a consolidated view of all open orders with the same data as shown in FIG. 48. The relative price axis 386 allows a user to gauge the relative distance of any order from that security's bid or ask price. The first column 414 from FIG. 48 is hidden from view. A Position Guide 134 and stock ticker input area 416 above the grid, allow quote information to be shown, and order quantity recommendations to be made. Dragging from the Position Guide 134 to the grid 380 allows the user to drop a buy, sell, or short order for the quoted security onto the grid. Placing the order on the BID price row, or below, of the grid designates it to be a limit buy order. Placing the order on the ASK price row, or above, of the grid designates it to be a limit sell or a limit short order. Placing a buy order above or on the ask price designates it as a market buy order; and placing a sell order on or below the bid price designates it as a market sell order. The row price bins may be adjusted using the drop down menu 418 near the relative price axis.
[0543] FIG. 50 is a representation of multiple securities quoted in one grid 430 with one price axis 432. The price axis 432 is adjusted in real time to reflect prices for the security assigned to a selected column 434a . . . 434g. In FIG. 50, XYZ Corp is the security of the selected column and the price axis matches trading activity in XYZ Corp. The column name of XYZC is highlighted at 436 to distinguish it as the price axis reference, and as the selected columns.
[0544] This representation of the grid 430 makes it convenient to monitor multiple options and equities in a single, simple presentation. It also assists in tracking options prices when the underlying equity changes. The price bin settings adjust to references a specific column displayed so they do not need to be constantly adjusted. The selected column may also be dragged to the left or left aligned automatically so that it is next to the price axis. The Position Guide 134 is active and relevant for the selected security.
[0545] The price axis can show absolute values, or relative values.
[0546] The security of a selected column can be changed by entering a second symbol in the symbol text box. Summary information on the security 440 appears on the upper section of the tab page. The tab 442 for IBM is highlighted in the tab set. This is an indication that an event has occurred that requires the user's attention. Such events maybe orders that are filled, a trade through an important price level, or a recent news release.
[0547] FIG. 51 is a representation of a grid 450 consisting of both order cells 462, and quote cells 454. Quote cells 454 represent a single security, and move on the grid in real time in accordance with a derived difference calculation between two or more parameters. Order cells 462 represent a limit order and can be dragged and dropped on the grid to adjust the order cell price in real time. Order cells are associated with a given security's quote cell. As the quote cell and the order cell move towards each other along the price axis, the order comes closer to being filled. When the order cell and the quote cell are on the same price axis segment, the order has the highest probability of being filled, as it is at the last trade price.
[0548] A selected grouping of stocks may be shown in this grid representation. Grouping may be index, industry sector stocks, a user defined list of securities, or a grouping selected on the basis of some technical criteria. The relative price axis 456 can show the difference value between two selected criteria. If a relative price axis is used, the axis can be referenced to the bid, ask, last trade, high, low, open, prior closing price values, or a technical indicator associated with the underlying security, all as shown in box 463. For example, a security close to its 50 day moving average can have the price axis referenced to the 50 DMA value, and the user can monitor the security to see if it holds the support level or falls under the moving average.
[0549] Two examples illustrate the use of this grid representation 450. In the first example, assume that a specific value on the relative price axis is derived from the difference between the prior closing price of a security and the last trade price during the current session. The grid 450 shows a quote cell 460 for IBM at negative 0.30 on the price axis. This is understood to mean that IBM's last trade in the current session is $0.30 below yesterday's closing price on IBM. The buy order 462 on IBM is seen to be $0.50 below yesterday's closing price, and $0.20 below the current last trade of IBM. If IBM falls, the quote cells will appear to fall towards the buy cell. If IBM continues to fall through the buy order, the order will be filled and reported as such. If the user feels that IBM will fall significantly past the buy order, the user can drag the buy order 462 down the column in order to lower the buy price for the IBM order as referenced along the relative price axis.
[0550] In the second example, assume that a specific value on the relative price axis is the difference between the value of the 50 day moving average (50 DMA) of a stock and its last trade price. In this case, if we look at IBM at cell 460, we would interpret the grid as indicating that IBM is trading $0.30 below its 50 day moving average. The IBM buy order 462 represents a price point of $0.50 below IBM's 50 DMA. If IBM falls in price during the current trading session, the quote cell 460 would fall on the grid towards the buy order for IBM If IBM continues to fall through the buy order 462, the order will be filled and reported as such. If the user feels that IBM will continue to fall further below the current buy price, the user can drag the buy order down the relative price axis in order to lower the buy price for the IBM order.
[0551] Orders can be entered directly from the tab page by selecting a quote cell. The Position Guide 134 will display a share recommendation for the selected security, which can be adjusted as desired, and dragged onto the grid to the desired position in relation to the quote cell. A preferences button 464 allows users to customize settings and display options, and to create complex formulae, for the derived price axis value 456.
[0552] It should be understood that the relative price axis value is derived by a price difference between two technical indicators, such as a moving average, or the prior session's closing price, and the last trade price of the displayed quote cell for any given security. The two values needed to derive the difference signal can be based on a simple statistic such as the last price, or the prior closing price. However, the two values can also be based on complex formulae involving multiple variables. With the use of multiple quote cells and groups of securities, general market trends would be more evident in this view than in a view of a single equity. A falling market would show the majority of quote cells falling on the grid. As noted earlier, the axis 456 values can be locked in position, or float to show the most representative view of all cells.
[0553] FIG. 52 represents a further, more orderly view of a grid with a relative price axis, wherein each column is associated with a unique security. The relative price axis 456 of FIG. 51 remains, as does the input methods (although not shown) to derive the difference value. An order status area 460 above the grid 450 allows fills to be reported for easy reference. Securities in a column can be changed by double clicking a column heading or name, and entering an alternative ticker symbol in the text box 462.
[0554] Quote cells 464 and any order cells 466 for a specific security are located within a designated column 468a . . . 468f for that security. Each column can contain stocks, options, or other securities. Price quotes used to derive the relative price axis value can be combined from one or more market participants.
[0555] Turning now to FIGS. 53a, 53b, and 53c, there are shown representations of how prices associated with a sequence of rows can be grouped into a single row as the price range is expanded. On the left side of each of FIGS. 53a, 53b, and 53c, there are five rows 531, 532, 533, 534, and 535. For example, as the bin size is changed from 0.01 to 0.05, the price range of the price axis visible on the grid expands. The nominal bin price of 59.90, shown at the right side of each FIGS. 53a, 53b, and 53c, can be assigned from the top 531a, center 533b, or bottom 535c position of the five rows. Which five values are mapped to a five-cent bin, and how the nominal price of the nominal bin is selected, is defined by the user in the user preferences, or by the trader's brokerage.
[0556] Since orders are usually not entered in increments finer than the Minimum Price Variance (MPV), the basic price range on a grid is based on the MPV. The number of distinct MPV price levels associated with a particular price bin is a function of the specific security, volatility of the security, and the user preference of the font end. Price bin rows contact when a grid is zoomed out to show a birds eye view of trading activity. How smaller rows, such as 0.01 increment rows, map into larger 0.05 bin rows, affects how a bin cell shows a quote, and how it does not, as discussed above.
[0557] A standard protocol is utilized so as to define the format of instructions and data that are exchanged between the front end 32 and any backend system 44. That standard protocol may be based on XML.
[0558] Each of the input parameters and each of the return value items for the set of instruction and data noted above is linked to a respective GUI object in the software which is at any trader's front end 32.
[0559] In another embodiment of the present invention, a component-oriented approach is used to implement the "grid-based graphical interface" as a software object. Such an approach is in keeping with modern software development technology, which currently favors the construction of application programs based on distinct units called "components" or "objects".
[0560] A software object is a self-contained, re-usable programming construct that encapsulates both data and behavior. Software objects utilized according to the principles of component-based software development facilitate the creation of application programs using pre-built building blocks. This fact greatly simplifies software development, and helps shorten the software development life cycle. Major software vendors like Microsoft Corporation and Sun Microsystems, among others, have adopted and are increasingly promoting scomponent-based software technology. Microsoft Corporation has its Component Object Model(COM), ActiveX, and Web Services technologies, while Sun Microsystems has its JavaBeans, Enterprise JavaBeans, Java applets, and Swing/JFC component technologies.
[0561] A software object implementing the functionality of the "grid-based graphical interface" of the foregoing descriptions is shown in FIG. 54. It will be noted that what is shown in FIG. 54, is actually a blow-up of the grid graphical object 52 depicted in FIG. 5.
[0562] The software object executes on a computer and has two aspects: (1) its visual manifestation, which is displayed on the computer screen, and which a user sees and interacts with; and (2) its program logic, which is implemented in computer code. The software object's program logic includes six methods or processes, which the software object employs to accomplish its tasks. However, it is also to be noted that the six processes noted below are only representative of all possible combinations of methods and processes that the software object may employ.
[0563] The software object's visual manifestation is composed of one or more axes, a drawing area, and GUI objects (icons, images, geometric shapes). The software object's visual manifestation is where trading data is graphically presented. This graphical presentation can employ several styles.
[0564] It must be stated that the software object's visual appearance can exactly match the visual appearance of the "grid-based graphical interface" of the foregoing descriptions, as seen at 500 in FIG. 54.
[0565] The software object's program logic consists of the following processes: (1) Connect process 502; (2) Retrieve process 504; (3) Transform process 506; (4) Display process 508; (5) Interpret User Input process 510; and (6) Send Instructions/Receive Feedback process 512.
[0566] The Connect process 502 issued by the software object to establish connections with one or more data sources, 514.
[0567] The Retrieve process 504 is used by the software object to receive trading data from a data source 514.
[0568] The Transform process 506 is used by the software object to process the trading data it receives from data sources 514.
[0569] The Display process 508 is used by the software object to plot and render GUI objects, each one representing an order or a quote, on the software object's drawing area 520.
[0570] The Interpret process 510 is used by the software object to receive and interpret inputs coming from the user. These inputs might be commands to change the graphical properties of the visual manifestation, or they might be inputs that effect a trading transaction.
[0571] The Send Instructions/Receive Feedback process 512 is used by the software object to automatically generate and transmit transaction instructions, as a result of the user's interaction with specific elements of the software object's visual manifestation. This process 512 also receives feedback data pertaining to the status of the previously transmitted transaction instructions.
[0572] A Data Source 514 is any system that can supply trading data. It can be any or a combination of the following: securities exchanges, stock markets, currency markets, commodities exchanges, electronic communication networks (ECNs), brokerage firms, data feed providers, market simulation software, and trading data published on any suitable media (such as CD-ROM).
[0573] A Market Participant System 516 is any system that can receive, validate, route, and possibly execute trading orders. It can be any or a combination of the following: securities exchanges, stock markets, currency markets, commodities exchanges, electronic communication networks (ECNs), brokerage firms, order-entry firms, and market simulation software.
[0574] Often times, the Data Source 514 and the Market Participant System 516 are one and the same system. This is the case, for example when the Data Source is Island.TM. ECN, and the Market Participant System is also Island ECN.
[0575] FIG. 55 illustrates yet a further visual manifestation of the object's visual appearance 500, with the data being presented in a more iconic fashion. As seen, however, a somewhat different convention is used, in that bid prices are shown with round icons 501, ask prices are shown with square icons 503, a buy order is shown with an hexagonal icon 505, and a sell order is shown with a trapezoidal-shaped icon 507.
[0576] Each of FIGS. 54 and 55 show prices and trading activity for a selected security, with the activities of several market participants being indicated. The same data is shown in each of the FIGS. 54 and 55. Also, the same data are shown in FIG. 3.
[0577] An interactive grid-based graphical trading system, and the interactive relationship of the trading system where a plurality of traders and a plurality of market participants will be found, has been described.
[0578] The software, and particulars of the software, have been described to the extent necessary, it being understood that any person skilled in the art of writing software for the appropriate platform such as ActiveX, Windows, GUI-based systems, and so on, may write specific software, and may provide specific functional and logical architecture, without departing from the spirit and the scope of the appended claims.
[0579] Other modifications and alterations may be used in the design and manufacture of the apparatus of the present invention without departing from the spirit and scope of the accompanying claims.
[0580] Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not to the exclusion of any other integer or step or group of integers or steps.
