How to calculate the profit and loss of stock index futures?
Stock index futures contracts take the settlement price of the day as the basis for calculating the profit and loss of the day. The specific calculation formula is as follows: daily profit and loss = ∑ [(selling price-settlement price of the day) × selling quantity]+∑ [(settlement price of the day-buying price )× buying quantity]+(settlement price of the previous trading day-settlement price of the day) × (selling position of the previous trading day-buying position of the previous trading day). For example, an investor held a stock index futures contract 10 in the previous trading day, and the settlement price in the previous trading day was 1500 points. On that day, the investor bought 8 long positions in the contract at the transaction price of 1505, and sold 5 positions at the transaction price of 15 10. The settlement price of the day is 15 15, so the profit and loss of the day is calculated as follows:

Profit and loss of the day = (1510-1515) × 5+(15-1505 )× 8+(/)

If the contract multiplier of the contract is 300 yuan/point, the investor's profit and loss on that day is 205 points ×300 yuan/point =6 1500 yuan. In fact, it is relatively simple and familiar with the formula. Just do a few more operations. I hope I can help you.
