(1) If there are quotations from buyers and sellers in the computer system of the exchange at the close, the settlement price of the unfinished contract shall be the middle value of the best buyer's quotation, the seller's quotation and the settlement price of the previous trading day of the contract.
(2) If the contract closing price is kept five minutes before the closing of the day, and there is only unilateral quotation in the computer system of the exchange, the closing price is the settlement price that has not been settled on the day.
(3) Except for items (1) and (2) above, the settlement price of futures contracts without transaction price shall be determined according to the following methods:
1. If there is no contract concluded on that day, and the fluctuation range (%) of the contract settlement price in the latest month before that day is less than or equal to the fluctuation range limit of the contract concluded on that day, then the settlement price of the contract concluded on that day = the settlement price of the contract in the previous trading day ×( 1+ the fluctuation range of the contract settlement price in the latest month before that day).
2. If there is no contract on that day, and the fluctuation range (%) of the settlement price of the contract in the latest month before that day is greater than the price limit of the contract on that day, the settlement price of the contract on that day = the settlement price of the contract on the previous trading day ×( 1+ price limit of the contract).
3. If there are no contracts clinched on that day, and there are no contracts clinched in all previous months on that day, and the fluctuation range of the contract settlement price in the latest month before that day cannot be found, then the contract settlement price clinched on that day = the contract settlement price of the previous trading day.
