ECN (2)

Electronic Communication Network

A computer system that facilitates over-the-counter trading as well as exchange trading. The electronic communication network sends buy or sell orders to the appropriate specialist on the floor of a stock exchange, bypassing the floor broker. A company running an ECN charges a fee for its services.


Electronic communications network (ECN).

An ECN is an alternative securities trading system that collects, displays, and executes orders electronically without a middleman, such as a specialist or market maker.

Trading on an ECN allows institutional and individual investors to buy and sell anonymously. Further, ECNs facilitate extended, or after-hours, trading.

ECN trade execution can be faster and less expensive than trades handled through screen-based or traditional markets, though the volume is sometimes thin.

However, some ECNs have been approved for official stock exchange status, expanding the number of stocks that can be traded on their systems.
