In the international market, stock index futures are all delivered in cash, and there are four main ways to determine the settlement price of delivery, namely: the average price of the spot market for a period of time on the last trading day; The closing price of the spot market on the last trading day; Special opening price of spot market on delivery date; The weighted average price of trading volume within a period of time after the spot opening on the delivery date.

In order to prevent the risk of market manipulation more effectively, in the settlement rules of China Financial Futures Exchange, the settlement price of Shanghai and Shenzhen 300 stock index futures is the arithmetic average price of the last two hours of the last trading day of the underlying index. Trading ownership adjusts the settlement price of stock index futures according to market conditions.
