Abstract: Disclosed are systems and methods for placing and processing test orders and real orders.

Abstract: In various embodiments, a data signal differentiates between real and test trading orders and a computer system processes the orders based on differing values.

Abstract: In various embodiments, real and test trading orders are processed and results are transmitted back to the entities originating the orders.

Abstract: A system for processing a composite trading order comprises a memory operable to store market data received from one or more market centers. The system further comprises a processor operable to generate a composite value based at least in part on the market data. The processor is further operable to receive a composite trading order associated with at least a portion of the composite value. The processor is further operable to generate a plurality of constituent trading orders that, when filled, combine to satisfy the composite trading order.

Abstract: An apparatus for processing a composite trading order comprises an interface operable to display a composite value representing a weighted quantity of a plurality of trading products. The apparatus further comprises a processor operable to receive at least one input representing a composite trading order, wherein the at least one input comprises a quantity that is equal to at least a portion of the weighted quantity. The at least one input is usable to generate one or more constituent trading orders that, when filled, combine to satisfy the composite trading order.

Abstract: In various embodiments, test trading orders are generated, transmitted and ranked.

Abstract: A system for replenishing trading orders comprises a memory coupled to a processor. The memory stores a trading order comprising a total quantity of a product, and at least one formula to determine a displayed quantity for the trading order. The processor applies the formula to determine the displayed quantity. The processor further determines a reserved quantity based on the determined displayed quantity and the total quantity. The processor communicates the trading order having the determined displayed quantity and the determined reserved quantity.

Abstract: In various embodiments, a data signal is received from a computer system. The data signal includes an order for an instrument and further includes an indicator. The indicator indicates that the order is one of a real order or a test order. The order is a test order. A test order that specifies a bid cannot bind an originator of the test order to tender money. A test order that specifies an offer cannot bind the originator of the test order to tender the instrument. The order is matched to another order. Whether the order is a test order or a real order is determined, based at least in part on the indicator.
