In futures, long positions correspond to short positions, and one hand buys and the other hand sells, otherwise it will not be possible to close the transaction and can only be hung. On the delivery date, according to the regulations, if you don't close your position on your own, you must force your position to be closed. Similarly, at the time of delivery, long positions and short positions are settled at the same time, and the positions correspond. The delivery date is, but not necessarily, the futures and spot will definitely rise at the same time, depending on whether the futures are premium or discount, and so on. For example, in the past, stock index futures mostly fell on the delivery date, but also rose in a small part of the time, depending on the specific situation.
