Abstract: A system and method is provided to allow traders to submit midprice orders to trade at a price within a spread of a market, preferably at the midpoint of a spread market, while maintaining anonymity of the midprice order. A midprice order is anonymous because other traders do not know whether the submitted midprice orders are orders to buy or orders to sell. A midprice order may remain active until it is traded with a contra midprice order or until a parameter associated with the order is breached, thereby resulting in cancellation of the midprice order.

Abstract: A computer-based transaction system manages representations of a plurality of positions in a first type of financial instrument, such as bond future contracts. The transaction system, at a first predetermined time, converts each position in the first type of financial instrument into a corresponding position in a second type of financial instrument, such as bonds. At a second predetermined time that is after the first predetermined time, the transaction system converts each position in the second type of financial instrument into a position in the first type of financial instrument.

Abstract: According to one embodiment, a method of managing trading is provided. In a market for a particular type of instrument, electronic data including buy orders and sell orders are received from a plurality of traders. Each buy order has an associated bid price and each sell order has an associated offer price. A determination is made of whether the particular trading order is an outlying trading order by electronically determining whether the particular trading order differs from at least one comparison price by more than a threshold value. If it is determined that the particular trading is an outlying trading order, a restrictive action is taken regarding one or more trading orders. For example, if a trader subsequently submits another trading order that would trade with the outlying trading order, an electronic alert message may be sent to the trader and the subsequent trading order may be prevented from trading with the outlying trading order at least temporarily.

Abstract: Systems and methods are provided for routing trading orders. The system determines that a first trading entity disclosed to the trading platform a reserve quantity of a first trading order received from the first entity. The system determines that a second trading entity did not disclose a reserve quantity of a second trading order received from the second trading entity. The system receives a third trading order. The system preferences the first trading entity over the second trading entity in the routing of trading orders, e.g., by routing the third trading order to the first trading entity.

Abstract: The invention relates to systems and methods that provide a user interface for use with an electronic trading system. The interface displays a bid price axis and an ask price axis, as well as corresponding sizes, and an indication of the inside market. When the inside market changes in response to changing market conditions, the indication of the inside market changes locations before being restored to its original location by shifting the bid and ask prices in a direction parallel to the bid or ask price axis. The user may enter trade commands at different price levels using an input device. In order to help prevent such trade commands from being entered at erroneous price levels, the system locks a pointer associated with the input device to a price the user points to during the shifting process, unless the pointer is moved away from that price.

Abstract: A system for managing electronic trading, comprises an interface application including a mapping module that defines a plurality of controller signal relationships. Each controller signal relationship associates one or more of a plurality of game controller signals with one of a plurality of trading system commands associated with the electronic trading of financial instruments.
