Day Order
Unless an investor specifies a time frame for the expiration of an order, orders to buy and sell a stock are “Day” orders, meaning they are good only during that trading day. Day orders that do not execute during regular trading hours expire and will not automatically carry over into after-hours trading or the next regular trading day.
