## Title
Method, apparatus and interface for trading multiple tradeable objects

## Abstract

An interface for trading multiple tradable objects includes a price axis or scale. A first indication of quantities represented in a market for a first tradable object is displayed in association with the price axis or scale. A second indication of quantities represented in the market for a second tradable object is displayed in association with the price axis or scale. The first tradable object may be different than the second tradable object. Alternatively, the first tradable object and the second tradable object may be the same, but the indications of quantity may be provided from different sources, such as different exchanges.

FIELD OF THE INVENTION
The present invention relates generally to the electronic trading. More specifically, it relates to a method, apparatus and interface for trading multiple tradable objects.
BACKGROUND
Trading methods have evolved from a manually intensive process to a technology enabled, electronic platform. Advances in technology are having an increasingly large and broad impact on trading and the way in which exchanges conduct business. What was previously seen as just a supplement to the traditional pit trading, electronic trading platforms continue to increase in importance and popularity. The advent of electronic trading has meant that a customer can be in virtually direct contact with the market, from practically anywhere in the world, performing near real-time transactions, and without the need to make personal contact with a broker. Electronic trading systems are also convenient for floor brokers on the floor at an exchange for receiving orders electronically.
Many exchanges throughout the world now support electronic trading systems. Electronic trading has made it easier for a larger number of people with many different trading strategies to participate in the market at any given time. The increase in the number of potential traders has led to, among other things, a more competitive market, greater liquidity, and rapidly changing prices. In the electronic trading environment, speed is of great importance with respect to both the receipt of market data from the exchanges and the delivery of transactions to the exchanges. The risk of loss can be substantially increased if information flowing in either direction is out of date.
Exchanges that implement electronic trading are generally based on one or more centralized computers (host), one or more networks, and the exchange participants' computers (client). In general, the host forms the electronic heart of the fully computerized electronic trading system. The host's operations typically cover order-matching, maintaining order books and positions, price information, and managing and updating the database for the online trading day as well as nightly batch runs. The host is also typically equipped with external interfaces that maintain online contact to quote vendors and/or other price information systems.
Typically, traders can link to the host via a client through one or more networks, where a network may include a direct data line between the host and the client, or where a network may include other common network components such as high-speed servers, routers, and gateways, and so on. For example, a high-speed data line may be used to establish direct connections between the client and the host. In another example, the Internet may be used to establish a connection between the client and the host. There are many different types of networks known in the art that may link a trader to the host.
Regardless of the way in which a connection is established, a client device allows a trader to participate in the market. The clients typically use a software trading application to produce interactive trading screens. The trading screens enable the traders to enter and execute orders, obtain market quotes, and monitor positions while implementing various trading strategies including those previously used on the floor of an exchange. Such strategies incorporated into an electronic marketplace can improve the speed, accuracy, and ultimately the profitability of trading electronically.
For certain trading strategies, traders may be interested in monitoring and participating in markets for two or more tradable objects. Known trading applications have limited capabilities to address this interest. For example, market information for one tradable object may be displayed in a trading interface in a first trading window and information on a second tradable object may be displayed in a second trading window. Another available alternative provides limited market information about a first tradable object in one row of a table and market information about a second tradable object in a different row of the table. A disadvantage of these known trading applications is that the trader who is interested in both tradable objects must take the time to try to discern the current relationships between the tradable objects. Order entry is also complicated by the multiple windows and/or multiple rows of market information.
It would therefore be desirable to have an improved apparatus, method and interface for trading multiple tradable objects.

DETAILED DESCRIPTION
1. General Overview of an Electronic Network
FIG. 1 shows an example host exchange, gateway, and client device that implements the trading of multiple tradable objects in accordance with a preferred embodiment. In a preferred embodiment, the system generally includes a host exchange 100, a gateway 102, and a client device 104. Preferably, the system can support up to X host exchanges, Y gateways 102, and Z client devices (although X host exchanges, Y gateways, and Z client devices are not shown for sake of clarity), where X, Y, and Z represent any number. In an illustrative embodiment, X and Y may be the same number such that there is a one-to-one correspondence between host exchanges 100 and gateways 102, but such numerical correspondence is not required.
Examples of host exchanges 100 include an Electronic Communication Network (ECN) like Island, which is a well-known electronic trading facility. Another host exchange 100 might be, for example, the Chicago Mercantile Exchange (CME), the Xetra (a German stock exchange), or the European derivatives market (Eurex). The preferred embodiments are not limited, however, to any particular exchange, and it should be understood that any entity that provides electronic market information, accepts electronic orders, and/or provides order status information may function as the host exchange. As known in the art, the gateway 102 is one or more computers (or program(s)) running software that receives information from the host exchange in the form of price information, order information, and fill information. Also known in the art, the client device 104 is a computer or equivalent device that receives one or more data feeds from the gateway 102. The host exchanges 100, gateways 102, and client device 104 are explained below in their respective sections.
It should be understood that the preferred embodiments are not limited to any particular network architecture, but rather may be applied with utility on any electronic device in any network that can be used for electronic trading. Furthermore, the preferred embodiments are not limited to a completely electronic trading environment where orders are sent to an electronic matching engine. For example, the invention could be utilized with an electronic trading application that sends orders electronically to a terminal where a person (e.g., a floor broker) executes those orders in a traditional open outcry trading floor.
Host Exchange
Each different host exchange 100 typically provides different types of information, and relays this information, or some portion thereof, collectively referred to as a data feed, over a network to market participants or traders. A data feed from one exchange may contain different information, e.g. representing different tradable objects, than another data feed from a second exchange. Different host exchanges may also provide different amounts of information, e.g. market depth away from the inside market, and may provide information in different formats. However, it is not necessary in the preferred embodiments that the data feeds from exchanges either include the same data or different data.
As used herein, the term “tradable objects” refers simply to anything that can be traded with a quantity and/or price. It includes, but is not limited to, all types of tradable objects such as financial tradable objects, which can include, for example, stocks, options, bonds, futures, currency, and warrants, as well as funds, derivatives and collections of the foregoing, and all types of commodities, such as grains, energy, and metals. The tradable object may be “real,” such as products that are listed by an exchange for trading, or “synthetic,” such as a combination of real products that is created by the user.
In general, a data feed 106 may include information representing prices and quantities for a tradable object. For example, the data feed 106 could include data relating to the “inside market” and/or data relating to “market depth.” The inside market is the highest bid price and the lowest ask price available in the market. Data feeds 106 from some exchanges also include data corresponding to quantities available at the inside market prices and at other prices—this may be called the market depth. Market depth may be represented by the available order book, including all the current bid and ask quantities and their associated prices, or any portion thereof. In other words, market depth is at least a portion of the available pending bid and ask quantities entered at a particular price. The data feed 106 can contain other types of market information, such as the last traded price (LTP), the last traded quantity (LTQ), total traded quantity (TTQ), order information, and/or fill information. The information in a data feed 106, whether it contains the inside market and/or market depth or more market information, is generally categorized into three groups referred to as price, order, and fill information.
In one embodiment, each host exchange 100 sends a data feed 106 to a gateway 102. The data feed 106 preferably carries all of the information that the exchange 100 provides, such as price, order, and fill information, and alternatively may include more information. The host exchange 100 may send its data feed 106 to the gateway 102 over a dedicated line 108, which is a communication channel that permanently connects the exchange to the gateway. Dedicated lines may be private or leased lines such as T1 lines, which are known by those skilled in the art. Or alternatively, the host may send its data feed to the gateway over a switched network such as a wide area network (WAN), Internet, PSTN, legacy networks that utilize X.25 protocol or also IBM LU6.2 SNA protocol, satellite broadcast systems that use leased satellite channels to broadcast price data, or a packet switched network, such as ATM or Frame relay, which are connection methods known by those skilled in the art. As noted above, the preferred embodiments are not limited to any particular network architecture. The foregoing examples are provided merely to illustrate the wide variety of networks to which the preferred embodiments may be applied.
According to the embodiment of FIG. 1, if there were five exchanges, then each exchange would have a gateway, and then according to this example there would be five gateways (i.e., X=Y). When a trader wants to participate in the market at two of the five exchanges, he or she may subscribe only to the data feeds that correspond to those two exchanges. If the trader decides to drop one of the exchanges or add another exchange, he or she may preferably do so at any time.
In another embodiment, each host exchange sends a data feed to a single gateway. For example, if there were five exchanges, then each exchange would send its data to the single gateway. Then, when a trader wants to participate at two of the five exchanges, he or she can simply subscribe to the data feeds that correspond to those two exchanges at the gateway. Also, if the trader decides to drop one of the exchanges or add another exchange, he or she may do so at any time. Of course, a hybrid system, in which multiple exchanges share a single gateway while other exchanges utilize distinct gateways, may alternatively be used.
In yet another embodiment, some exchanges may have multiple gateways, so that if there were five exchanges, then there might be three gateways supporting each of them; for fifteen gateways. This embodiment allows for a load balancing, among other benefits, of the gateways' workstations.
The preferred embodiments are not limited to any particular mathematical relationship between the number of host exchanges and the number of gateways. Those skilled in the art will appreciate that any of the foregoing examples, as well as combinations of these examples or entirely different architectures, may alternatively be used.
Gateway
As mentioned earlier, the gateway 102 is a computer (or program) that receives information from the host exchange. As used herein, a computer includes any device with memory and a processor capable of processing information to produce a desired result. Thus, a gateway can be a computer of any size such as a server, workstation, personal computer, or laptop, but generally, the gateway is any computer device that has the processing capability to perform the function described herein. Moreover, it should be understood that the functions of the gateway could be moved to the exchange and/or the client device to reduce or eliminate the need for a gateway.
In one embodiment, the gateway 102 receives a data feed 106 from an exchange 100. Preferably, the gateway 102 receives the data feed 106 and converts it to a form compatible with the protocols used by the client device 104 using conversion techniques known in the art. As known by those skilled in the art, the gateway 102 may have one or more servers to support the data feeds, such as a price server 114 for processing price information, an order server 116 for processing order information, and a fill server 118 for processing fill information. Generally, a server is a computer or program that responds to commands from a client in the form of subscriptions. The “servers” here may run on the same machine or may run on independent machines. A trader at a client device can subscribe to price information, order information, and fill information for that exchange. Once a client device has subscribed to the information, the gateway 102 publishes the information to the client device 104.
Client Device
As mentioned before, the client device 104 may be a computer or equivalent device, such as a workstation, that allows a trader to participate in the market hosted at the exchange. The client device 104 is not limited to any particular hardware and/or software, but rather may be any device that is capable of communicating with an exchange 100. For example, the client device 104 may be a personal computer, terminal, workstation, personal digital assistant (“PDA”), smart phone, or any other wired or wireless communication device.
In general, the client device uses software that creates specialized interactive trading screens on a terminal associated with the client device. The trading screens enable traders to enter and execute orders, obtain market quotes, and monitor positions. The range and quality of features available to the trader on his or her screens varies according to the specific software application being run. In addition to or in place of the interactive trading screens, the client device may run automated non-interactive types of trading applications.
A commercially available trading application that allows a user to trade in a system like that shown in FIG. 1 is X_TRADER® from Trading Technologies International, Inc. of Chicago, Ill. X_TRADER® also provides an electronic trading interface, referred to as MD TraderTM, in which working orders and/or bid and ask quantities are displayed in association with a static price axis. The preferred embodiments, however, are not limited to any particular trading application that performs the translation, storage and/or display functions. Portions of the X_TRADER® and the MD TraderTM-style display are described in U.S. Pat. No. 6,772,132, entitled “Click Based Trading With Intuitive Grid Display of Market Depth,” and U.S. Pat. No. 6,938,011, entitled “Click Based Trading With Market Depth Display,” the contents of both of which are incorporated by reference herein. Moreover, the trading application may implement tools for trading tradable objects that are described in U.S. Pat. No. 7,389,268, entitled “Trading Tools for Electronic Trading,” the contents of which are incorporated by reference.
2. Trading Multiple Tradable Objects
Using an electronic network like that described above, any client device 104 is capable of receiving data feeds relating to multiple tradable objects from one or more host exchanges 100, so that a trader may participate in more than one market. For example, using the MD TraderTM-style display of the X_TRADER® trading application, a trader may open a separate MD TraderTM-style display window for each tradable object in which the trader is interested, subject to the number of windows that can be displayed on the display screen(s) or monitor(s) of the trader's client device 104. In accordance with a preferred embodiment, however, a single trading window for multiple tradable objects is provided, allowing the trader to visualize the relationships among the multiple tradable objects while participating in their corresponding markets.
Trading two or more tradable objects may be of interest to traders who, for example, are trading spreads, seeking arbitrage opportunities, or executing other trading strategies. In addition, some traders attempt to simultaneously trade two or more tradable objects that are identical, other than being offered at different exchanges, or related, such that there is a natural relationship in their price movements. In accordance with a preferred embodiment, therefore, a multiple tradable object graphical user interface is provided to assimilate two or more presentations of market information and/or order entry into one screen for trading the multiple tradable objects.
Multiple Tradable Object Graphical User Interface
FIG. 2 shows a graphical user interface 200 for trading multiple tradable objects in accordance with a preferred embodiment. The graphical user interface 200 includes a price axis 202, which, in this example, is presented as a vertical column. Other orientations may alternatively be used, such as horizontal or at an angle to create a three-dimensional effect for example. The price axis 202 (which can be displayed or not displayed) may be referred to herein as being “static,” which means that information relating to the tradable objects, such as bid and ask quantities or working orders are displayed dynamically relative to the price axis so that the indicators associated with the inside market can move along the price axis when the market changes. It should be understood that, in this context, static does not mean immovable on the display, but rather means fixed in relation. For example, the static price axis 202 may be moved or repositioned on the display as a result of a command from a user (such as a recentering or repositioning command), but the prices on the axis remain fixed in relation to each other, subject to consolidation or expansion as described below.
The prices may be arranged along the price axis 202 in predetermined steps or increments. The smallest increment on the price axis 202 is generally the “tick size,” which may depend on the particular tradable object and is typically set by the host exchange as the smallest increment on which the tradable object may trade. Although the axis described herein is a “price” axis, those skilled in the art will recognize that the axis may alternatively be a scale of any characteristic that is capable of representing value for the tradable objects. For example, the axis may represent yield or volatility rather than price.
In the embodiment shown in FIG. 2, the graphical user interface 200 supports the trading of two tradable objects. A first tradable object indicator 204 displays an indicator that represents the first tradable object, and a second tradable object indicator 206 displays an indicator that represents the second tradable object. The indicators may be the registered trading (or ticker) symbols associated with the tradable objects, but, in an alternative preferred embodiment, the indicator may be determined by the trader or an administrator (such as where multiple client devices are used by an entity). As a further alternative, the trading application may associate indicators with tradable objects. An example indicator is color. In cases where the same product is traded at more than one host exchange, each product/host exchange combination may be treated as a different tradable object with a unique indicator. An advantage of this tradable object definition is explained below with reference to an illustrative application for the interface. In yet another alternative embodiment, the graphical user interface 200 may be modified to accommodate more than two tradable objects, as described below.
For each tradable object, the graphical user interface 200 preferably presents at least a portion of the order book information distributed by the host exchange. Thus, the graphical user interface 200 includes a first tradable object bid quantity region 208 and a first tradable object ask quantity region 210. The graphical user interface 200 also includes a second tradable object bid quantity region 214 and a second tradable object ask quantity region 216. The regions 208, 210, 214 and 216 collectively illustrate at least a portion of the market depth for the tradable objects of interest, in this example by displaying pending order quantities in association with the price axis 202. Alternatively, the graphical user interface 200 could just display indicators associated with the inside market price levels of the tradable objects.
For the embodiment shown in FIG. 2, the regions 208, 210, 214 and 216 are vertical columns arranged in nested pairs about the price axis 202, with bid quantities being displayed on one side of the price axis 202 and ask quantities being displayed on the other side of the price axis 202. The price axis 202 is also illustrated as a vertical column. Of course, the regions 208, 210, 214 and 216 and the price axis 202 may alternatively be arranged as rows or in any other manner to illustrate the relationship between market depth and a price axis. In addition, although the nested pair arrangement of the market depth for multiple tradable objects is preferred, an alternative embodiment allows the user to arrange the regions 208, 210, 214 and 216 in any desired order in relation to the price axis 202. In this embodiment, the regions 208, 210, 214 and 216 allow for the dynamic display of bid and ask quantities relative to the static price axis 202.
The preferred embodiments are not limited to any particular arrangement of prices and quantities and, in particular, are not limited to two-dimensional grid displays. Three-dimensional grid displays, and two-dimensional and three-dimensional graphical displays may alternatively be used. Nor are the preferred embodiments limited to any particular format for displaying prices and/or quantities. For example, it is not necessary that the prices and/or quantities be displayed numerically. Rather, graphical representations may alternatively be used. It is also not necessary that the market information be displayed relative to a static price axis.
In order to distinguish markets represented by the quantity regions 208, 210, 214 and 216, the regions may be color coded. For example, the regions 208 and 210 may be displayed in a first color or shades of the first color, and, likewise, the regions 214 and 216 may be displayed in a second color or shades of a second color. Color may also be used to provide additional information to the trader about the markets for the multiple tradable objects. For example, color gradients may be used to illustrate which market has greater depth, shorter queues, or the lowest latency. Other uses for color, which may be applied to the preferred embodiments, are described in U.S. Pat. No. 7,389,268.
In order to facilitate the display of multiple tradable objects, and in particular the market depth of multiple tradable objects in relation to a common price axis, the graphical user interface 200 may include a first tradable object offset indicator 220 and a second tradable object offset indicator 222. The offsets 220 and 222 are provided to skew, by the selected number of ticks or cells, the quantities displayed for the respective tradable object relative to the price axis 202.
Preferably, the offsets 220 and 222 may be set, selected and/or adjusted by the user. As will be recognized by those skilled in the art, the particular form of the offset is dependent upon the relationship between the tradable objects that are being displayed. As a result, the offset may take whatever form is necessary to display the multiple tradable objects in relation to a common, normalized scale. For example, the offset may be a multiplier or divisor, an equation, or a fixed number that may be added to or subtracted from the disseminated price of a tradable object. The equation may include factors, based on data available to the client device 104, in addition to the disseminated price. For example, the equation may perform a rounding function for the case in which the multiple tradable objects trade with different tick sizes. Alternatively, the user may choose an equation based on his or her perception of a mathematical relationship among the tradable objects. The use of offsets therefore provides a great deal of flexibility in normalizing tradable objects in relation to a common axis.
It should be noted, however, that the use of offsets is optional and not necessary for the preferred embodiments. For example, offsets are not required in cases where the multiple tradable objects are the same underlying product at different host exchanges. In addition, although separate offsets 220 and 222 are described, a single offset representing the relative adjustment between the tradable objects may alternatively be used.
U.S. Pat. No. 6,772,132, entitled “Click Based Trading With Intuitive Grid Display of Market Depth,” and U.S. Pat. No. 6,938,011, entitled “Click Based Trading With Market Depth Display,” the contents of both of which are incorporated by reference herein, describe interfaces that not only display market information in relation to a price axis, but also allow a user to enter and track orders. A preferred embodiment of the present invention extends this order entry and tracking capability to multiple tradable objects using a single trading window.
As shown in FIG. 2, the graphical user interface 200 includes a first tradable object working quantity region 212 and a second tradable object working quantity region 218. Again, while both are illustrated as columns, it will be appreciated that, like those described above, the regions 212 and 218 may alternatively be presented in rows or in any other manner to illustrate the relationship between the working orders and a price axis. It should be noted that it is not necessary that there be a separate working quantity region for each tradable object. For example, a single working quantity region column may be used as an alternative, where the working orders for the different tradable objects are distinguished, such as by the use of color, graphics, or additional text. Nor is it necessary that the graphical user interface 200 include order entry or tracking capabilities.
For the embodiment of FIG. 2, indicators associated with working orders for the first tradable object preferably may be displayed in the first tradable object working quantity region 212 at a location that corresponds to the price on the price axis 202 at which the order is pending. Likewise, indicators associated with working orders for the second tradable object may be displayed in the second tradable object working quantity region 218. Preferably, a working order indicator displayed in the regions 212 and 218 includes information regarding partial fills of working orders. In other words, the working order regions 212 and 218 may display indicators that include an indication of the quantity in each working order that has been filled, as well as the quantity that remains to be filled. When a working order is completely filled, the indicator associated with that working order is preferably no longer displayed in the working order region 212, 218.
In one embodiment, order parameters may be set directly from the graphical user interface 200. Each tradable object represented in the multiple tradable object graphical user interface 200 preferably has an order configuration area 230. In the embodiment shown, a distinct order configuration area 230 is provided for each tradable object. A single order configuration area 230 for multiple tradable objects may alternatively be used. The location of the order configuration area 230 with respect to the graphical user interface 200 is not critical; it may appear in any convenient location.
As illustrated in FIG. 2, the order configuration area 230 of the graphical user interface 200 preferably includes an order quantity keypad 232, which the trader may use to select the quantity associated with subsequent orders, such as by clicking with a mouse or other pointer on the appropriate number in the order quantity keypad 232. The order configuration area 230 may alternatively or in addition include cells for other order parameters, like conditions for execution (e.g., all or none, time in effect, etc.). It may also include a market order button to automatically submit a market order for a selected quantity of the tradable object and delete buttons that if depressed cause all buy or sell orders to be deleted. The order configuration area 230 may also include a delete all button that if depressed causes all orders to be deleted. Those skilled in the art will appreciate that additional order parameters may be readily incorporated into the order configuration area 230.
Preferably, the trader may also set order parameters using a drop down menu or order parameter dialog window. In accordance with one embodiment, order parameters that are set in this manner remain in effect until changed by using either the order configuration area 230 or the drop down menu/dialog window. The preferred embodiments are not limited, however, to embodiments in which the trader may set order parameters.
As described in U.S. Pat. No. 6,772,132 and U.S. Pat. No. 7,127,424, limit orders may be submitted by clicking, using a mouse or other pointing device, within a region of the display at the level of the desired price on the price axis. Preferably, the graphical user interface 200 operates in a like manner. Specifically, a trader may submit a limit order by clicking within the appropriate bid/ask quantity regions 208, 210, 214 and 216 in the cell or area associated with the desired price on the price axis 202. The quantity associated with the limit order may be set in advance using either the order quantity keypad 232 or a drop down menu or dialog window. Again, however, the preferred embodiments are not limited to embodiments in which mouse clicks are utilized for order submission. In fact, the preferred embodiments may, in one alternative, merely display market information without providing any manner for submitting orders. In addition, the invention is not limited to embodiments in which the user must click within the bid/ask quantity regions, but can provide for other regions or areas of the display in which the user can click to submit orders.
Returning to FIG. 2, the graphical user interface 200 optionally provides the trader with an indication of the trader's current position. In particular, the graphical user interface 200 includes a first tradable object position indicator 224, a second tradable object position indicator 226 and a net position indicator 228. The first tradable object position indicator 224 indicates the quantity of the first tradable object (in this example “CBT”) that the trader has bought or sold, and the second tradable object position indicator 226 provides the same information for the second tradable object (in this case “BT”). In the example of FIG. 2, the trader is long 100 CBT and short 227 BT, for a net short 127 position. Preferably, the trader may define a relationship among the tradable object position indicators for determining the net position.
Although described with reference to a graphical user interface for trading two tradable objects, the graphical user interface 200 may be extended to trade more than two tradable objects, for example by adding, for each additional tradable object, a corresponding bid quantity region, ask quantity region, working quantity region, an order configuration area, and a tradable object position indicator. Of course, if the interface is not to be used for order entry, then the working quantity region and the order configuration area need not be displayed. Depending on the tradable object, a tradable object offset may also need to be defined.
In an alternative embodiment, market information regarding multiple tradable objects may be consolidated for display. Price consolidation is described in U.S. Pat. No. 7,127,424, entitled, “Click Based Trading With Intuitive Grid Display of Market Depth And Price Consolidation,” the contents of which is incorporated herein by reference. In cases where price is represented along a vertical axis, price consolidation may be thought of in terms of the vertical consolidation of the axis, where multiple price levels are condensed into a single price level.
In accordance with this alternative embodiment, consolidation may be applied to other market information, such as quantities associated with two or more of the multiple tradable objects. In this case, however, the consolidation takes effect across quantity cells. For example, two or more of the quantity regions, such as the regions 208, 210, 214 and 216 in FIG. 2 may be combined. Specifically, if two tradable objects are being traded and the bid quantities are displayed in columns, the two bid quantity columns may be consolidated into a single bid quantity column. This approach is particularly advantageous in cases where the multiple tradable objects are actually the same underlying products but they are being traded at different host exchanges.
It is to be understood that this alternative embodiment including consolidated market information is not limited to use in a graphical user interface that includes a static axis representing price or value. To the contrary, it may be implemented in a wide variety of graphical user interfaces, which may either include or not include a static axis representing price or value.
FIG. 3 is an alternative embodiment of the graphical user interface of FIG. 2 in which market information, in this case the bid and ask quantities, is consolidated. In the user interface 300 of FIG. 3, the bid quantity region 208 and the bid quantity region 214 from FIG. 2 are combined into a consolidated bid quantity region 302. In the illustrated example, the combined bid quantity region 302 is a vertical column that is displayed in association with a price axis 304, although as noted above the display of the price axis 304 is optional. Similarly, the ask quantity regions 210 and 216 from FIG. 2 are combined into a consolidated ask quantity region 306.
Preferably, the user has the option of viewing the market information in consolidated form, as illustrated in FIG. 3, or as distinct markets, as illustrated in FIG. 2. In other words, one variation of this alternative embodiment is a graphical user interface that is capable of switching between the form shown in FIG. 2 and the form shown in FIG. 3 based on a user input.
In the consolidated market information display of FIG. 3, as well as the user interface shown in FIG. 2, color may be used to provide additional information to the user. For example, in the consolidated display, quantities that represent combined markets from two or more host exchanges may be presented in a first color, whereas quantities that are available at only one of the host exchanges may be presented in a different color. In accordance with a preferred alternative, an indicator is activated when the markets for the tradable objects cross. For example, color, highlighting or a different font may be used to indicate that the markets are crossed at a particular price level, thereby drawing the trader's attention to that particular market information. This technique may be used with a graphical user interface of the type shown in FIG. 2 as well as with the consolidated user interface of FIG. 3.
For the embodiment shown in FIG. 3, the interface 300 supports order submission. It should be understood, however, that the preferred embodiments are not limited to interfaces that support order submission, but rather encompass interfaces that merely display market information. When the market information is consolidated, as illustrated in FIG. 3, the trading application supporting the client device preferably handles the routing of orders entered in a consolidated field, such as a consolidated bid quantity field or a consolidated ask quantity field. Orders may be entered using a mouse or other pointing device, as described above, or in any other manner. FIG. 4 is a flowchart of a process 400 to route orders entered using the graphical user interface of FIG. 3.
Preferably, the user may designate a preference to send orders to a favored market. For example, the user may prioritize or rank, using a drop down menu or dialog window, the host exchanges at which the tradable objects associated with the consolidated market information are traded. Many factors may influence a user's routing preference. For example, routing decisions may be made based on the exchanges' clearing and/or transaction costs or margin requirements. Other factors may include the length of the order queue at the desired price, the age of the most recent price and/or quantity update, or the time required for a user's order to reach the host exchanges (also referred to as network latency or connection speed). Of course, other factors may alternatively be used to make routing decisions.
Orders may then be routed based on the ranking. Alternatively, the trader may define ratios for the host exchanges, and orders route in accordance with the defined ratio applied to the total order quantity. As a further alternative, the trading application may route the orders automatically, such as by randomly selecting a host exchange, routing the order to the host exchange that sent the most recent update, routing the order to the exchange with the lowest transaction costs, or selecting the host exchange with the shortest order queue at the order price or the lowest network latency. These automatic routing parameters are preferably selectable by the trader, such as through a drop down menu or a dialog window.
In another alternative, the trader may indicate routing instructions through an input device on an order-by-order basis. For example, where the input device is a mouse, the right click may be assigned to route orders to a first host exchange and the left click may be assigned to route orders to a second host exchange. In yet another alternative, routing preferences may be incorporated directly into the user interface. For example, an offset, such as the offsets 220 and 222 shown in FIG. 2, may incorporate clearing and/or transaction costs of the corresponding host exchange. It is to be understood, however, that the preferred embodiments are not limited to any particular manner of selecting or inputting routing parameters, and the routing techniques described herein are optional rather than required.
Returning to FIG. 4, the process 400 begins at step 402 when a trader enters an order in a consolidated field. Next, the process 400 determines, at step 404, whether a user, such as the trader or an administrator, has defined routing parameters. If the user has defined routing parameters, the process 400 proceeds to step 406, where the order is routed in accordance with the user-defined parameters. As noted in the preceding examples, the user or trader may rank the host exchanges such that orders entered in consolidated fields are routed to the highest ranking host exchange at which the tradable object is traded. Alternatively, the user or trader may define a ratio for each host exchange at which the tradable objects are traded, and the orders route in accordance with the defined ratio applied to the total order quantity. After the order is routed, the process 400 returns, at step 408, to a ready state for entry of the next order.
If, on the other hand, there are no user defined routing parameters, then the process 400 proceeds to step 410. At step 410, automatic routing parameters are applied to the order. As noted in the preceding examples, the automatic routing parameters may dictate that the order be routed by randomly selecting a host exchange, routing the order to the host exchange that sent the most recent update, selecting the host exchange with the shortest order queue at the order price, etc.
Illustrative Application for the Multiple Tradable Object
Graphical User Interface
An illustrative application for the multiple tradable object graphical user interface is set forth below. This illustration is not intended to be exhaustive, but rather to highlight some of the benefits and advantages associated with the preferred embodiments. One of the advantages of the multiple tradable object graphical user interfaces described herein is that they provide, in a single window, a more accurate picture of the entire market for related tradable objects. Applications in addition to those set forth below will no doubt become apparent to those skilled in the art upon reviewing this detailed description.
For certain trading strategies, a trader may want to trade the same tradable object on two different exchanges. For example, a trader may want to simultaneously trade the 10Y Note future through the Chicago Board of Trade (CBOT) and the 10Y Note future through Brokertec. For this example, quantity consolidation, as described above, may also be beneficial because it provides the trader with a more complete picture of the entire market for this tradable object.
As a numerical example, assume that tradable object 1 and tradable object 2 are the same tradable object, but they are traded through different host exchanges. Because the different host exchanges provide markets for the same tradable object, however, the prices of tradable object 1 and tradable object 2 are almost always the same. At a time, t, the markets provided by the two host exchanges are the same, both bid-ask 30-30.5. At a later time, t+1, the markets momentarily diverge: the first host exchange offers a market in tradable object 1 at 29.5-30, while the second host exchange offers a market in tradable object 2 at 30-30.5. The divergence will be readily obvious to the trader using the multiple tradable object graphical user interface described above because the bid and ask quantities for tradable object 1 and tradable object 2 are displayed side-by-side.
In addition, the indicators representing quantities to buy or sell at the price 30 (in this example) may be highlighted on the display. The highlighting of the divergence of the markets for tradable object 1 and tradable object 2 may be useful information for a trader. Traders may use this information differently depending on their personal trading strategies. For example, if a trader is looking to fill one leg of a spread by buying a 10Y Note future, the trader can use the information from the multiple market display to find the best price. Another example is a situation where a trader is looking for arbitrage opportunities—the multiple market display readily illustrates when the markets diverge.
Other illustrative applications for the multiple tradable object graphical user interface include trading fungible products, basis trading and/or tradable objects which the trader believes have a certain relationship. Those skilled in the art will recognize, upon reading this detailed description, other applications as well. The multiple tradable object graphical user interface embodiments described herein may be used to trade any group of tradable objects in which a relationship among the objects can be defined.
Trading Using a Multiple Tradable Object Graphical User Interface
FIG. 5 is a flowchart of a preferred method 500 for trading two or more tradable objects using the graphical user interface of FIG. 2. At step 502, market information regarding multiple tradable objects is received. In accordance with the terminology used herein, a tradable object that is traded at more than one host exchange may be considered multiple tradable objects, where each individual tradable object corresponds to the tradable object as it is traded at a particular host exchange. The network architecture of FIG. 1, for example, may be used to obtain market information from one or more host exchanges. Of course, other network topologies may alternatively be used. The market information preferably includes market depth in addition to the inside market. It may also include a last traded price and quantity, and/or a total traded quantity.
At step 504, the method receives a tradable object selection from the user. The tradable object selection includes an identification of two or more tradable objects that the user desires to trade. For the greatest advantage, the selected tradable objects should be related, for example as described in the Examples set forth above.
The method proceeds to step 506, where market information for the user selected tradable objects is presented to the user. In accordance with a preferred embodiment of the method, the market information is presented on a display to the user by associating the market information for the selected tradable objects with a single static price axis. Preferably, the market information is presented on an interactive user interface. In one embodiment, the presentation of market information includes bid and ask quantities for each selected tradable object that are dynamically displayed in association with the static price axis, as illustrated for example in FIG. 2. In another embodiment, the market information may be consolidated, as illustrated for example in FIG. 3. In addition to market information from the host exchanges, the user interface preferably displays working orders to the user and also provides order entry functionality.
Preferably, the method further includes, at step 508, receiving orders from the user regarding the selected tradable objects. As described above, a user may place orders using the interface by clicking, using for example a mouse or other pointing device, in the quantity regions (or any region or area of the display designated for order entry) at the appropriate price level. At step 510, the user's orders are routed to one or more host exchanges. Where one or more of the market information fields are consolidated, orders may be routed automatically or in accordance with user preferences, as described above.
It should be understood that the programs, processes, methods and apparatus described herein are not related or limited to any particular type of computer or network apparatus (hardware or software), unless indicated otherwise. Various types of general purpose or specialized computer apparatus may be used with or perform operations in accordance with the teachings described herein. While various elements of the preferred embodiments have been described as being implemented in software, in other embodiments hardware or firmware implementations may alternatively be used, and vice-versa.
