To trade during pre-market or post-market hours, you must place a limit order.
When placing your order, you will be able to choose between two execution options:
Extended hours – allows your order to be executed during pre-market (4:00 AM – 9:30 AM ET), regular market hours (9:30 AM – 4:00 PM ET), and post-market (4:00 PM – 8:00 PM ET).
Market open – your order will only be executed during regular market hours (9:30 AM – 4:00 PM ET).
