The liquidation profit and loss is the opposite of the position profit and loss, which is the profit and loss of futures traders when they actually close their positions. Closing profit and loss are mainly divided into closing profit and loss on the same day and closing profit and loss on the same day. The profit and loss extended to liquidation refers to the profit and loss of liquidation on the previous opening day.

The calculation formula of liquidation profit and loss is:

Profit and loss of liquidation on that day = (closing price-opening price) × liquidation amount;

Deferred to liquidation surplus = (liquidation price-settlement price of the previous day) × liquidation amount.

When selling and closing positions, the positive number in the above formula is profit and the negative number is loss; When buying a peace warehouse, the situation is just the opposite. When calculating the investment income, the above liquidation gains and losses shall be deducted from the trading commission.
