The reference profit and loss of the day refers to the profit and loss of futures contracts calculated at the settlement price of the day. The profit of the day is included in the member settlement reserve, and the loss of the day is deducted from the member 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 customers' transactions. According to the different calculation methods of profit and loss, it can be divided into two methods: marking the market day by day and hedging one by one. The profit and loss of the day is settled by marking the market day by day.

A futures contract is an agreement in which the buyer agrees to receive assets at a specific price after a specified time, and the seller agrees to deliver assets at a specific price after a specified time. The price that both parties agree to use in future transactions is called futures price. The designated date on which both parties must conduct transactions in the future is called settlement date or delivery date. The assets that both parties agree to exchange are called "targets". If an investor obtains a position in the market by buying a futures contract (that is, agreeing to buy it at a future date), it is called a long position or a futures long position. On the contrary, if the position obtained by investors is to sell futures contracts (that is, to assume the contractual responsibility for future sales), it is called short positions or short futures.

Transaction characteristics

1. Small and wide. Futures trading only needs to pay 5- 10% performance bond, and it can complete several times or even dozens of times of contract transactions. Due to the leverage effect of the futures trading margin system, it has the characteristics of "small and wide", and traders can use a small amount of funds to conduct large transactions, saving a lot of working capital.

2. Two-way transaction. In the futures market, you can buy first and then sell, or you can sell first and then buy, so the investment method is flexible.

3. Don't worry about the performance. All futures transactions are settled through the futures exchange, which becomes the counterparty of any buyer or seller and provides guarantee for each transaction. So traders don't have to worry about the performance of the transaction.

4. Market transparency. Trading information is completely open, and trading is conducted by means of open bidding, so that traders can compete openly under equal conditions.

5. Tight organization and high efficiency. Futures trading is a standardized transaction with fixed trading procedures and rules, which are linked one by one and operate efficiently. A transaction can usually be completed in a few seconds.
