Market value gains and losses are for overnight positions. If you don't know the position of the order opened on the same day, you will have a mark-to-market profit and loss on the second trading day. Because futures are settled on the same day, even if they are not settled on the same day, the exchange will settle according to the settlement price of the day. The settlement price is calculated according to the weighted average price of the transaction price on the day of the futures contract, that is, the yellow line closing price. Market value gains and losses are calculated relative to the settlement price of the previous trading day.

Floating profit and loss reflects the actual profit and loss from opening position to current holding.
