No, some kinds of futures are free of charge within the days specified by the exchange, that is, if the positions are closed on the same day, only the opening fee is charged, and no closing fee is charged. I won't list the specific varieties in detail. The futures company will make it clear to you and charge them all according to the regulations of the exchange. If the exchange does not stipulate that the variety is free, it will be charged bilaterally, and the Kaiping warehouse fee is the same as that of the stock.
