After the futures close, the profit and loss are calculated at the settlement price, which is the yellow line on the disk. For example, you will understand.

1, futures price rose from 10 yuan to 20 yuan, settlement price 15 yuan. If you buy in 18 yuan, you are actually profitable in 2 yuan. After the settlement, give it to Chuanduo, indicating that your 3 yuan is a loss, which is a loss on the book and does not affect your actual income.

2. And vice versa. On that day, the futures price rose from 10 yuan to 20 yuan, and the settlement price was 15 yuan. If you bought it at 18 yuan, the settlement shows that you made a profit in 3 yuan and actually lost money in 2 yuan. This is the futures settlement system.

The daily settlement system, also known as "mark-to-market" and daily debt-free settlement system, refers to the exchange's settlement of profits and losses, trading deposits, handling fees, taxes and other expenses of all contracts at the settlement price of the day after the end of daily trading, and the transfer of receivables and payables at the same time, so it is necessary to increase or decrease the settlement reserve of members.
