As a friend of futures retail investors, it must be clear that if individuals can't deliver in kind, they must not move their positions before the delivery date, which is too dangerous. It's best to move a day or a week in advance? Commodity futures are delivered in kind, and individual investors have no delivery authority. Individual investors can only go to the last trading day one month before the delivery month.

Futures companies will inform customers in advance to change the month, and the exchange will substantially increase the margin ratio of the contract in the middle of the month before the delivery month.
