Reverse liquidation-if you open more than one position (buy contract), when you close your position, you will close more than one position (that is, sell); If you are an open short position (selling contract), when you close the position, you close the short position (that is, buy); It is to reverse the liquidation at the current market price. If it is financial futures (such as stock index futures), it will be settled in cash at the time of delivery. If it is commodity futures, individuals are not allowed to make delivery and must close their positions before maturity.
