NYSE Arca(redirected from NYSE ArcaEx)
NYSE Arca, one of the two securities exchanges operated by the NYSE Group, Inc., is the first open, all-electronic stock exchange in the United States.
Trades are executed quickly -- electronically and anonymously -- on the US market trading center with the best available price. Among the securities traded on Arca are individual stocks, exchange-traded funds, and equity options.
NYSE Arca was formed by the merger of the NYSE and Archipelago Exchange, an electronic communications network (ECN), creating what is known as a hybrid market.
