If your "look Ahead" margin(shown in account tab under margin requirements) of your account is deficient you will receive a warning at 3:50pm ET that you have 10 mins. At 4:00pm ET you will get another warning that auto-liquidate will commence. I think you get 60-90 seconds after 4:00 before they liquidate.
Thank you very much for the detailed answer.
