CHX is an integral part of the National Market System. CHX competes with all U.S. equity markets. CHX offers the ability to transact business in virtually all equity securities traded on NYSE, AMEX, NASDAQ, or other national securities exchanges. With a robust Matching System and connectivity to multiple order sending firms and market makers, CHX systems offer functionality beyond the simple matching of orders. CHX is an ideal venue for hedge funds, options market markers, quantitative traders, professional traders, and active individual traders that require immediate and automated execution, in addition to serving the needs of traditional broker-dealer clients and the individual investors they represent.
