Stock index futures
Today's settlement price
2 consecutive price limits (3 for commodity futures)
The weighted average price of the last hour of the Shanghai and Shenzhen 300 futures contracts calculated by volume.
There was no deal in the last hour, and the price was still rising/? On the daily limit, the stop-loss price is used as the settlement price of the day.
There was no deal in the last hour and the price didn't go up/? On the daily limit board, the weighted average price of the transaction price in the previous hour is taken according to the volume. If there is still no deal during this period, push it forward for another hour. And so on. If the trading time is less than one hour, the weighted average price of the whole period shall be taken.
If there is no transaction price on that day, the settlement price shall be determined as follows:
(1) If there are bilateral quotations at the closing, the average price of the highest buying price and the lowest selling price in the market shall be the settlement price;
(2) If there is no buyer's quotation in the market at the closing time, the lowest selling price in the market shall be the settlement price;
(3) If there is no seller's quotation in the market at the closing time, the highest purchase price in the market shall be the settlement price;
(4) At the closing, there is no quotation between the buyer and the seller, and the contract closest to the delivery month with the transaction on that day is taken as the benchmark contract. The calculation formula of the settlement price of this contract on the same day is: contract settlement price = yesterday's contract settlement price+today's benchmark contract settlement price-benchmark contract settlement price on the previous trading day.
If the contract is a new listed contract, the calculation formula of the settlement price of the day is: contract settlement price = contract benchmark price+benchmark contract settlement price today-benchmark contract settlement price on the previous trading day.
(5) If the settlement price of the day cannot be determined by the above method or the calculated settlement price is obviously unreasonable, the settlement team of the Exchange has the right to decide the settlement price of the day separately.
