Q: What is order duration, pre-market trading and post-market trading?

Order Duration Unlike S.A. stock trading, there is no time expiration rules for U.S. stock orders. Any order that is not executed of the day will expire automatically. Pre-market Trading Pre-market trading is the period of trading activity that occurs before the regular market session. It typically occurs between 8 a.m. and 9:30 a.m. EST each trading day, though it can begin as early as 4 a.m. ET. Many investors and traders watch the pre-market trading activity to evaluate the strength and direction of the market in anticipation of the regular trading session. Post-market Trading Post-market trading is the period of time after the market closes when an investor can buy and sell securities outside regular trading hours. Both the New York Stock Exchange (NYSE) and the Nasdaq Stock Market trades during the post-market session can be completed anytime from 4 p.m. to 8 p.m. EST. Note: The trading volume of pre-market and post-market tend to be low because of the lower amount of traders, so your orders may not be filled immediately.
