According to the settlement price of the current transaction, the settlement institution calculates the floating gains and losses of the open contracts of members and determines the amount of the deposit payable for the open contracts. The calculation formula is as follows: floating profit and loss = (settlement price of the day-opening price) × position × contract unit-handling fee. Futures profit and loss calculation, if the calculation method of futures trading profit and loss is positive, it means long floating profit or short floating loss. Negative values are just the opposite. If there is a floating loss in the account and the amount of margin is not enough to maintain the open position contract, the settlement institution will inform the members to make up the difference before the market opens the next day, that is, add margin, otherwise it will be forced to close the position. If the account is a floating profit, the profit part cannot be withdrawn unless the contract is closed and the floating profit becomes an actual profit.

2. Calculate the actual profit and loss.

The profit and loss realized by liquidation is called actual profit and loss. The formula for calculating the actual profit and loss of bulls is:

Profit and loss = (closing price-buying price) × position × contract unit-handling fee.

The calculation method of short-term profit and loss is:

Profit and loss = (selling price-liquidation) × quantity held × contract unit-handling fee.

Futures profit and loss calculation formula:

The quotation of futures = the quotation of a single trading point (1t/ 1g).

Futures contract value = latest quotation * trading unit

Futures margin cost = latest quotation * trading unit * margin ratio (the margin ratio of each product is different, and the latest one can be obtained from me according to the fluctuation of the exchange).

Multiple single profit and loss = (closing positions-opening positions) * profit handling fee fluctuation at one point.

Empty order profit and loss = (opening position-closing position) * income-handling fee for fluctuation by one point.

In addition, we often hear "short"/"strong". The so-called short position/strong position refers to the risk rate >; 100%
