If there is no price in call auction, the first transaction price of the day shall be the opening price of the day. If there is no transaction on the whole day, the settlement price of yesterday shall be taken as the opening price of the day. Closing price refers to the final transaction price on the day of the contract. If the contract is open all day, the opening price is the closing price of the day.
