Extended Hours Trading
Extended hours trading is a way for investors to place stock trades outside of normal exchange hours. The regular exchange hours for US stock markets are 9:30am - 4pm Eastern Standard Time (EST), Monday through Friday, excluding holidays. Pre-market trading can take place from 7:00am - 9:30am while after hours trading can take place between 4:00pm and 8:00pm, though the specific hours vary from broker to broker.
How Does it Work?
Extended hours trading is made possible by electronic communications networks (ECNs), which are automated systems that match buy and sell orders. Two of the largest ECNs are NSDQ, which is owned by NASDAQ, and NYSE Archipelago (ARCA), which is owned by the New York Stock Exchange.
Some brokers require users to accept an extended hours agreement form (usually via their website). Once users have access, the stock trading menu usually has a separate tab or order entry selection to submit extended hours trades.
