VIRTUAL PAYMENT PROCESSING SYSTEM

A system, apparatus, and method for resolving a data transaction is provided in which data transactions are resolved by a hardware matching processor that identifies data transaction requests received from client devices over a data communication network, matches incoming transaction requests with previously received transaction requests, and, based thereon, transmits electronic data transaction results messages to the client device. An incoming data transaction request is received and a match is attempted with one or more previously received but not yet resolved data transaction requests. It is identified whether either the incoming data transaction request or the matching data transaction request are dependent on the resolution of another data transaction request and whether that dependent data transaction request has been resolved. The data transaction requests are resolved and/or stored based on the match and resolution of dependencies.
