Abstract: The present invention provides a trading keyboard that can be configured both physically and functionally according to a user's preferences. The trading keyboard preferably includes self-identifying key covers that can be physically arranged on any of the keyboard's key bases. Detection mechanisms included in the key bases detect the commands of the trading application associated with each self-identifying key cover. Therefore, the user may reposition the key covers on the keyboard according to the user's preferences, and yet retain the same functionality for the key covers. The user may also switch between keyboard modes that allow the keyboard to be functionally reconfigured. By selecting different modes, the user can chose between different keyboard mapping configurations that assign the functions of the trading application to the keys in different arrangements. The mode selection mechanism may also be used to select between different commands associated with a single key or key cover.

Abstract: According to one embodiment, a system for electronic trading is provided. The system includes an interface application having an associated mapping module that defines a plurality of controller signal relationships. Each controller signal relationship associates a game controller signal with a trading system command associated with the electronic trading of financial instruments. The interface application is operable to receive a particular game controller signal, determine the trading system command associated with the particular game controller signal using the mapping module, and communicate the determined trading system command such that the trading system command is executed.

Abstract: The present invention is systems and methods for matching desired purchases and sales of mis-matched items. These systems and methods compare the requirements of potential buyers and sellers of items against those of sets of other potential buyers and sellers of items to construct transaction sets that will enable an optimal transaction or set of transactions for the parties involved. The present invention may be used to match purchases and sales of any items, such as goods, services, financial instruments, and property interests (e.g., ownership interests in real property, possessory interests in personal property, etc.).

Abstract: Systems and methods for providing an interactive graphical representation of a market for an electronic trading system are provided. A graph may be displayed on a display of a workstation in an electronic trading system. In one example, the graph may include a curve corresponding to a range of values of a financial instrument. In another example, the graph may include symbols that represent bids and offers for one or more financial instruments. A user may be allowed to select a portion of the graph. In response to the user's selection, a trading dialog box may be provided, thereby allowing the user to place a trade directly from the graph.

Abstract: A method for managing electronic trading is provided. In an electronic market having trade matching rules, a plurality of first orders each associated with an account are received. A contra order is also received at the electronic market. For each of one or more first orders, it is electronically determined whether that order is a related first order by determining whether the account associated with that order has a particular relationship with the particular account associated with the contra order. Without intentionally introduced delay, one or more particular first orders, including one or more related first orders, are electronically determined to trade with the contra order based at least on the trade matching rules and the determination of related first orders. One or more trades between the one or more particular first orders and the contra order are automatically executed.

Abstract: The invention relates to systems and methods that provide a user interface for use with an electronic trading system. The interface notifies the user that the price at which he or she may have attempted to trade has changed and presents the user with the opportunity to submit, modify or cancel the trade command. The user may configure the trading system to enable such a notification based on the time span for the price change, the number of increments of the price change, a combination thereof or any other appropriate consideration for protecting against the occurrence of erroneous price entries. Subsequent trade commands, such as those entered by third parties, may be used to validate prices and execute trades at these prices.
