The types of delivery date can be divided into cash delivery date and futures delivery date.
Cash delivery date refers to two business days after the trading day; Generally speaking, the delivery date of the futures exchange refers to the delivery date calculated from the delivery date of the spot exchange plus several months. If the delivery date is not qualified, it can be further postponed. If it must be postponed until next month, it can't be postponed, but the other way around.
In commodity futures trading, individual investors have no right to hold positions before the final delivery date. If you don't close your position by yourself, your position will be forced to close, and these consequences will be borne by the investors themselves. Unless you are a spot enterprise that has applied for hedging qualification from the exchange and obtained approval, you are qualified to keep your position until the final delivery date, and then enter the delivery link.
