Of course. It is better to close a position when futures fall than to lock a position. Locking positions is mainly to make investors ashamed to lock in profits, not to lock in losses. The futures price limit should adopt a reasonable stop loss method, not a lock position. Closing futures is equivalent to cutting meat. The rights and interests of futures investors are the rights and interests in futures accounts. It is equal to all the deposits in the account plus the daily profit MINUS the daily loss. With the daily fluctuation of futures contract prices, the value of investors' equity in positions is also changing.
