In the event an account is not margin compliant, IBKR reserves the right to liquidate positions held in the account in order to bring the account back into compliance. In such a case, any position held in the account is subject to liquidation.
In addition to the above, IBKR has Physical Delivery Close Out Rules that require a futures contract with a physically delivered underlying to be closed or rolled to avoid a delivery. Information on the dates and times when IBKR may start the liquidation process are outlined on our Physical Delivery Close Out Rules.
Please be aware the times listed represent the times the liquidation process may begin. The actual liquidation time may vary in cases where a futures contract has no bid/ask, may be locked limit up/down or if the contract has little or no liquidity. In such cases, the IBKR Trade Desk will attempt to manually liquidate the contract.
