Stock index futures, also futures, have a time limit. Because stock index futures are delivered in cash, the last trading day and delivery date are the same day, which is the third Friday of the contract month and will be postponed in case of legal holidays.
The settlement price of delivery is calculated according to the weighted average price of the last two hours of the last trading day. The open position of stock index futures is calculated according to the ratio of delivery settlement price and account margin, and then the remaining funds are returned to the futures account after deducting the delivery settlement price.
For example, on August 9, 2022, the last trading day of the IF2209 contract, the settlement price is 4 166.6 points, the contract multiplier is 300 yuan \ points, the margin ratio of the futures account is 14%, and the settlement fee is 65438+ 0% of the transaction amount.
Then the calculated net value = 4166.6 * 300 *14% * (1-1%) =174979.7 yuan.
