How is the opening price of futures generated?

(1) The trading system ranks all valid buy orders from high to low according to the principle of price priority and time priority, and all valid sell orders from low to high according to the declared price.

(2) The trading system will match the buy and sell orders in front of the queue in turn until the transaction cannot be completed.

(3) If the last transaction is a complete transaction, that is, the number of buying orders is equal to the number of selling orders, the arithmetic average price of the declared buying price and the declared selling price of the last transaction is taken as the opening price; If the last transaction is a partial transaction, the declared price of some transaction orders will be taken as the opening price. The price is rounded off by the minimum change price of the futures contract.
