Abstract: An apparatus for processing trading orders comprises a memory and a processor. The memory stores a first order and a second order. The first order is associated with a product and comprises a displayed quantity and a reserved quantity. The second order is associated with the product and comprises a displayed quantity and a reserved quantity. The processor is coupled to the memory and receives a counterorder associated with the product. The processor fills the displayed quantity of the first order with a corresponding portion of the counterorder, and fills the displayed quantity of the second order with a corresponding portion of the counterorder. The processor allocates a first additional portion of the counterorder to the first order. The first additional portion is based at least in part on a ratio of the displayed quantity of the first order to a sum of the displayed quantity of the first order and the displayed quantity of the second order.

Abstract: Systems and methods for providing traders with an opportunity to trade on the VWAP price are provided. After a trader enters a VWAP auction session, the trader has a predetermined about of time (i.e., the length of the VWAP auction period) to place bids and/or offers on an item. When the VWAP auction period ends, the electronic trading application matches the VWAP orders. The VWAP orders that are not matched are cancelled. The electronic trading application collects trading information (e.g., price, size, etc.) corresponding to the received orders. The collected information is processed to determine the VWAP price. The VWAP price is presented to the trader and the matched VWAP orders are filled based on the determined VWAP price.

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 and/or possessory interests in real property, personal property, etc.).

Abstract: A method for enabling collaborative processing of data by one or more computers or digital data processing systems. The computer(s) compute a value representative of a first yield for a first instrument, the first instrument being a derivative of an underlying financial instrument, the first instrument being a non-fixed-income instrument. The computer(s) compute a second yield of a second financial instrument. The computer(s) control automated trading of the first instrument based at least in part on comparison of the first yield value with a computed second yield of a second financial instrument, and/or based on comparison of a differential of the first instrument value over change in market interest rates against a differential of the second instrument value over change in market interest rates, the control balancing sizes of positions in the first instrument and second instrument to achieve a desired financial risk profile.

Abstract: According to one embodiment, a method of managing trading is provided. In a market for a particular type of instrument, 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 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 the outlying trading order. For example, if a trader subsequently submits another trading order that would trade with the outlying trading order, an 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: 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: 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.
