Abstract: A deal feed system for passing deal tickets to back office systems comprises a deal feed contributor which receives tickets from trades on a plurality of trading systems on a plurality of trading floors, a database for storing the tickets, and a distributor for passing the tickets to back office systems. Virtual deal codes are defined to which a plurality of real deal codes map. The virtual deal codes to which a ticket relates is stored in a table with a reference to the stored ticket. A deal code table is updated with the range of the virtual deal code and the update transmitted to the bank office systems and to traders.

Abstract: An anonymous computerised trading system matches orders by conducting auctions at specified times. As well as entering orders, participants assign credit limits for the duration of the auction, thus minimising the time for which credit is allocated to the system.
