The profit and loss of the day is the profit and loss of the stocks held and the stocks traded on the day.

The reference profit and loss of the day is the profit and loss of the futures contract calculated based on the settlement price of the day. The profit of the day is transferred to the member's settlement reserve, and the loss of the day is deducted from the member's settlement reserve. It is the change in the account balance caused by the rise and fall of the stock price that day.

Futures companies settle their clients' transactions. According to different profit and loss calculation methods, they can be divided into two settlement methods: daily mark-to-market and transaction-by-transaction hedging. The profit and loss of the day is settled on a daily mark-to-market basis.

Extended information:

Futures contracts use the settlement price of the day as the basis for calculating the profit and loss of the day.

Profit and loss for the day = profit and loss from closing the position (mark to market on a daily basis) + profit and loss from the position (marking to the market on a daily basis)

Profit and loss from closing the position (marking to the market on a daily basis) = profit and loss from closing the historical position + closing the current position Profit and loss

Profit and loss from closing historical positions = ∑ (sell closing price - settlement price on the previous trading day) x selling closing volume + ∑ [(settlement price on the previous trading day - buying closing price) ) (excluding the opening price - the day's buying and closing price) x the buying and closing volume]
