Abstract: In an embodiment, an apparatus comprises a processor, and a memory that stores a program. The program, when executed by the processor, directs the processor to perform a method including the following steps: receiving an encrypted query, in which the query indicates at least one security, and at least one price; determining whether the encrypted query corresponds to any order in an encrypted data set that represents orders; outputting a response to the query, in which the response indicates whether the encrypted query corresponds to any order in an encrypted data set that represents orders; receiving order data that represents the orders; and encrypting the order data to yield the encrypted data set that represents orders.

Abstract: A system for controlling the disclosure of a trading order comprises a memory and a processor. The memory stores disclosure policies associated with market centers. The processor receives a trading order for a trading product that specifies a total quantity of the trading product and a maximum disclosure quantity of the trading product. The trading order is associated with a particular market center. The processor then routes the trading order to the particular market center according to the disclosure policy associated with the particular market center.

Abstract: A system for routing a trading order to a market center comprises a memory and a processor. The memory stores a trading order specifying a trading product. The processor determines a plurality of market center prices for the trading product, each market center price associated with at least one of a plurality of market centers. The processor selects one of the plurality of market centers based upon the determined market center prices. The processor further determines a disclosure policy for the selected market center and routes the trading order to the selected market center according to the determined disclosure policy.

Abstract: A system for routing a trading order to a market center according to price comprises a memory and a processor. The memory stores policy information, cost information, and rebate information associated with a plurality of market centers. The processor receives a trading order specifying a trading product, a plurality of market center prices for the trading order, and best price information for the trading product. The processor adjusts at least one market center price according to the policy information of the corresponding market center and the best price information. The processor also adjusts at least one market center price according to at least one of the cost information and the rebate information of the corresponding market center. The processor then compares the plurality of market center prices, and selects a particular market center based at least in part upon the comparison.
