Settlement in futures business refers to the process of calculating the profit and loss (including liquidation profit and loss and position profit and loss) of customers on that day according to the opening price, closing price and settlement price of position contracts of customers after daily trading. After settlement, the profit will be credited to the customer's capital account and the loss will be deducted.

If the customer's funds are insufficient to maintain the position after settlement, the futures company will issue a notice of additional margin to the customer, and the customer must put the additional amount of funds into the trading account before the market opens on the next trading day, otherwise the futures company will choose the right time to forcibly close the customer's excess position until the available margin is greater than zero.

After the daily transaction, the settlement will be made, and the transaction cannot be conducted naturally at this time. After the market opens the next trading day, customers can trade.
