Island Exchange, abbreviated ISLD, was an electronic securities exchange, now part of NASDAQ. Island changed its name to Inet ATS, Inc. ("Inet") effective November 17, 2003.
Island, like other electronic communication networks, was an order-pairing system that gives brokerage firms the power to electronically track and match reciprocal buy and sell orders at the same limit price and lot size.
Island's efficient and reliable systems reduce costs to both brokerage firms and investors and facilitate high speed pairings of buy and sell orders.
A high volume of trades were routed through Island, with over $5 billion USD handled daily in 1999.
Island was headquartered in New York City.
