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 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.

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: 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 computer-implemented, transaction-making, municipal bond trading system having a capability to conduct a private electronic auction of bid wanteds between a central brokers' broker and multiple prospective remote bidders and to maintain a reference database of accurate individual bond lot descriptions and identifications, including CUSIP (trademark) numbers.

Abstract: Apparatus and methods for automatically executing a trade of an item between a market participant who issues a request for a quote for an item and a market participant who responds to the request are provided. In some embodiments, an automatic trade may be conditioned upon the acknowledgement, by the participant who issues the request, of an obligation to execute the trade. In some embodiments, the invention may include one or more modules for receiving the request, receiving a quote, receiving a responsive number of units of the item to be traded, decrementing a time interval in which the participant who issues the request is required to trade, and, if that participant does not trade within the time interval, trading on behalf of that participant.
