Analysis: How to calculate the profit and loss of today's stock index futures?

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:

Profit and loss of the day = ∑ [(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)

The profit and loss of the day are transferred at the time of settlement, and the profit is included in the settlement reserve, and the loss is withdrawn from the settlement reserve.
