Hello, the futures stop loss is closed in the form of a pending order. Overnight exceeding the stop-loss price will trigger a stop-loss order, but the stop-loss is entrusted in the form of a pending order. If the price can't return to your stop-loss price, then your stop-loss order can't be closed. In this case, the stop loss will be invalid. Only when the price returns to your stop-loss price can your stop-loss order be closed and closed automatically!
