The profit and loss of the transaction has nothing to do with the settlement price. Futures trading is settled day by day, so the average price is used as the settlement price to calculate the profit and loss of the day. When the first-hand corn is opened in 2020, if the settlement price on that day is 2028, and the account profit is shown on the statement as 2028-2020=8* 10=80 yuan, the closing price on the next day is 2023-2028=-5* 10=-50 yuan, so it is actually. Therefore, the actual profit and loss can only be calculated according to the opening price and the flat price. If you are interested, you can chat with me at 765798556.
