If you fail to deposit the required margin within the specified time, the open contract you hold may be forced to close at a loss, and you must bear all the losses caused by it. You must carefully read and abide by the business rules of futures exchanges and futures companies. If you fail to meet the requirements stipulated in the business rules of futures exchanges and futures companies, your open positions may be forcibly closed according to relevant rules, and you must bear the consequences arising therefrom.
