The specific provisions of the Shanghai and Shenzhen 300 stock index futures price limit are as follows:
The price of stock index futures contracts is limited to 65438+ 00% of the settlement price of the previous trading day.
The daily limit of quarterly and monthly contracts on the first day of listing is 20% of the benchmark price. The benchmark price is determined by the exchange and announced in advance. If there are transactions on the first day of listing, the next trading day will return to the range of price limit stipulated in the contract; If there is no transaction on the first day of listing, the price limit of the previous trading day will continue to be implemented on the next trading day.
The price of stock index futures contracts is limited to 20% of the settlement price of the previous trading day.
Futures contracts are declared in the same direction in the unilateral market for two consecutive trading days, and they are sold at no stop price, or they are closed as soon as there is a stop price, but no stop price is set, and the trading day of the second unilateral market is the last trading day, then the contract is directly settled; The trading day of the secondary unilateral market is not the last trading day, and the trading ownership shall take one or more of the following risk control measures according to the market conditions: raising the trading margin standard, restricting the opening of positions, restricting the withdrawal of funds, closing positions within a time limit, forcibly closing positions, suspending trading, adjusting the range of price limit, forcibly reducing positions or other risk control measures.
There are two points that investors should pay special attention to: first, unlike stock trading, the calculation basis of the price limit of stock index futures contracts is the settlement price of the previous trading day, not the closing price. Second, the price limit is not fixed, and the exchange can adjust the price limit according to market risks.
