The US stock market is typically open Monday through Friday from 9.30am to 4pm (Eastern Time). You can still place a buy or sell order with Spaceship on the weekend or on a public holiday but your order won't be placed in market until your funds have cleared (in the case of buy orders) and the market is open.
Can I place buy and sell orders on weekends and public holidays?
