All positions must be closed BEFORE 4:59 PM EST Monday through Friday, before the market closes.
Starting at 6:00 PM EST, Monday through Thursday and on Sunday evening, you can start placing trades again.
This means that you are not able to swing trade or hold positions over multiple days.
What happens if I do not close the trade?
Any open positions will be automatically closed at 4:59 PM EST. This will not result in a fail or loss of account.
