US Classification:

705037000

Abstract:

A system and method that provides intra-day confirmation of non-anonymous trade transactions made at an exchange includes the entry into a computer system of first data relative to the trade transaction on behalf of one party to the trade transaction, wherein the first data include a code identifying an opposing party to the transaction. A message is sent to the designated opposing party prior to submitting the trade transaction for matching prior to end-of-day clearing. The trade transaction is matched to second data relative to the trade transaction entered into the system based on identity between certain elements of the first data and the second data, and a confirmation is sent to at least one of the parties to the trade transaction.
