Delivery date refers to the date when both parties agree to exchange money. As far as futures contracts are concerned, the delivery date refers to the date when the goods must be delivered. If you don't want to make delivery, you must close the futures contract before the delivery date or the last trading day.

Delivery date: According to the regulations of the Chicago Board of Trade, the delivery date is the third day in the delivery process. The settlement company of the contract buyer must deliver the delivery notice together with the fully confirmed cheque to the settlement company office of the contract seller on the delivery date.

However, CICC stipulates that the third Friday of each month is the delivery date of stock index futures, such as May 20th13, May 2nd1,and Friday is the delivery date of stock index futures contract 1005. Previously, people in the industry generally believed that there would be no delivery day effect in the market. Judging from the approaching trend on the 20th and the continuous decrease of contract positions in May, this judgment is obviously reasonable.
