System and method for buy-side order matching

1. A system for order matching in the trading of financial instruments, comprising:

a centralized matching engine having one or more transmitters and receivers, wherein the centralized matching engine is communicatively coupled to a network, the network including one or more first computer systems and at least one second computer system, wherein the one or more first computer systems are configured to communicate between one or more first parties and the centralized matching engine, and wherein the at least one second computer system is configured to communicate between a second party and the centralized matching engine;
