A system and method that automatically executes orders that a user enters into an entry screen at a global trade workstation. The order is routed to an order processing server, which opens a transaction record in a database. If the order is executable on an automated exchange, then the order is forwarded to that exchange. If the order is not executable on an automated exchange, then the order is sent to a front-end processor for non-automated exchanges. The front-end processor forwards the order electronically to the appropriate exchange. After execution of the transaction, the order processing server receives execution information from either the automated exchange or the front-end processor. The front-end processor matches this information to the order, stores the execution information and then forwards this information to the global trade workstation.
