This involves settlement price and latest price. Before the afternoon closing, your funds will be displayed at the latest price. For example, if you buy a hand of sugar, the entry price is 6000, and the latest price after the afternoon closing is 6 100, then your floating profit and loss is 1000 yuan. After a period of time in the afternoon, the exchange will calculate the settlement price according to the weighted average price of the transaction price and volume of futures contracts on that day. Then you can see that your profit at night is calculated according to the settlement price. For example, the settlement price of sugar on that day is 6080, so the floating profit of your position is 800, (6080-6000) *1*10 = 800. But your actual profit and loss is still calculated according to the price you entered. Don't worry.
