After the daily transaction, according to the regulations, the settlement price of the day should be determined. The settlement price of the day refers to the weighted average price of the transaction price of a futures contract according to the volume. If there is no transaction price on that day, the settlement price of the contract on that day shall be determined according to the following methods: if there is a quotation entrusted by the buyer and the seller on that day, the settlement price of the contract on that day shall be the intermediate price between the highest purchase price, the lowest purchase price and the settlement price of the previous trading day; If one party to the contract has no continuous quotation, the stop-loss price shall be taken as the settlement price of the contract on that day; If there is no entrusted quotation on the day of the contract, or there is a unilateral entrusted quotation by the buyer or the seller but there is no continuous quotation, the settlement price of the uncommitted contract on that day is calculated based on the previous completed contract that is closest to the uncommitted contract on that day: if the fluctuation range (%) of the settlement price of the benchmark contract on that day is less than or equal to the fluctuation limit of the uncommitted contract on that day, Settlement price of the contract that has not been concluded on that day = settlement price of the previous trading day of the contract × (65438+) If the settlement price (%) of the benchmark contract on that day is greater than the price limit when there is no contract on that day, the settlement price of the contract on that day = settlement price of the previous trading day of the contract ×( 1+ price limit of the contract on that day). . If the benchmark contract cannot be found, the settlement price of no contract on that day = the settlement price of the contract on the previous trading day; If the benchmark contract cannot be found on the first day of listing of the new contract, the settlement price of the unfinished contract on that day = listing benchmark price. If the new listing contract has not been concluded for three consecutive trading days, the exchange may adjust the settlement price separately.
