What is a market order?
A market order is an order to buy or sell a stock immediately at the best available current price. A real-time market order can be placed during regular market hours from 9:30am to 4:00pm EST Monday through Friday. Orders can also be placed on the web site after market hours. However, if an order is placed after market hours the order will be stored by the web site, and will be placed as a market order shortly after the market opening the next business day.
