Delivery is the settlement of funds between investors and securities companies in the settlement process. Except for B-shares, the securities (A-shares, funds and bonds) listed and traded in Shanghai and Shenzhen stock markets all implement the T+ 1 delivery system. T+ 1 system means that the stocks bought on the same day cannot be sold on the same day, and the funds can only be received and delivered on the next business day of the trading day, and the cash cannot be withdrawn from the account on the same day.

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.
