Presented is a system and method for performing crossing of institutional security orders. The system includes a first server interconnected to a second server and client stations across a communication network. The first server includes a database and is configured to receive institutional orders from the client station, which are stored in the database. The first server includes operating instructions operable to determine whether a match exists between contra institutional orders based on predetermined criteria. Upon determination of a match, the first server forwards a child order composed of at least a portion of one of the contra orders to the second server. At a fraction of a second later, the first server forwards the other of the contra orders to the second server followed by the remaining portion of the contra order.
