Abstract: An automated trade processing system including a record keeper for receiving participant mutual fund transaction requests. The record keeper also aggregates the participant mutual fund transaction requests by mutual fund into omnibus plan transaction requests. These requests are then transmitted in at least one file which has a plurality of fields of information about the omnibus plan transaction requests. A host processor, interacting with the record keeper, receives the at least one file, processes the omnibus plan transaction requests, verifies at least one of the plurality of fields of information, and trade-acknowledgment confirms the omnibus plan transaction requests to the record keeper. The host processor then transfers the omnibus plan transaction requests to a transaction executor which executes the omnibus plan transaction requests. The trade-acknowledgment confirmation occurs at a time prior to execution of the omnibus plan transaction requests.
