This gets around the problem. No slippage so far for the two trades that have been executed this way. One caution about setting the start of your trading window between 4pm and 7:59 pm if you are trading a margin account. IB does Reg-T margin checks near market close each trading day. They seem to have a window that starts 15 minutes prior to market close and extends for some (unknown) period of time after market close where 2X margin is enforced. Once that window closes then they are back to enforcing 4X through the end of the next trading day. This means you don't have to be concerned about execution order for closing/opening orders if you are near fully invested. If this is a concern for you, I would not submit the next day's orders until after 8 pm EDT. Steve | |
