Answer: Hello, mark-to-market profit and loss is one of the concepts of futures trading settlement. The settlement system of futures is the "daily debt-free settlement system", also known as the "daily mark-to-market system". That is, after the end of each trading day, the positions of all customers will be settled based on the settlement price, and those with profits will be transferred in and those with losses will be transferred out.

1. Example of mark-to-market profit and loss

Suppose a customer opens an account with 50,000 yuan and opens a position to buy 5 lots of soybeans on a certain day. The opening price is 3150 and the position is not closed at the closing time. The settlement price is 3135. Then the floating profit and loss is:

(3135-3150) yuan/ton × 5 lots × 10 tons/lot = -750

The beginning (capital) balance is 50,000, and the ending balance is 50,000 -750=49250 (for simplicity, handling fees are not taken into account)

Mark-to-market profit and loss is:

(3135-3150)×5×10=-750

< p>The customer's equity at the beginning of the period is 50000, and the customer's equity at the end of the period is 50000-750=49250

If the position is not closed the next day and the settlement price is 3170, the floating profit and loss is:

( 3170-3150) x 5 3170-3135)×5×10=1750

The customer’s equity at the beginning of the period (end of the previous trading day) is 49250, and the customer’s equity at the end of the period is 49251750=51000.

2. Position closing profit and loss

Closing profit and loss refers to the profit or loss generated after closing a position in futures trading. Futures closing refers to the purchase or sale by contract investors. For a contract with the same type code, quantity and delivery month but the opposite trading direction as the contract held, the behavior of closing the position, the profit and loss of the liquidation is divided into the profit and loss of the intraday liquidation and the profit and loss of the extended position liquidation. Intraday position closing profit and loss refers to the profit and loss of opening and closing a position on the same day, and extended position closing profit and loss refers to the profit and loss of closing a position on the previous opening day.

3. Futures floating profit and loss

Futures floating profit and loss, also known as trade-by-trade floating profit, refers to the profit and loss of a position relative to the opening price. For example, if you buy 1 lot of rebar for 2580 yuan, no matter how many trading days have passed, the price is 2620 yuan, and the floating profit and loss will be 400 yuan. Note that floating profit and loss is the difference between the price and the opening price. Floating profit and loss represents the profit and loss of your position from opening to position. Floating profit and loss. That is, the settlement institution calculates the floating profit and loss of the member's open contracts based on the settlement price of the day's transactions, and determines the amount of margin payable for the open contracts. The calculation method of floating profit and loss is: floating profit and loss = (settlement price of the day - opening price) × position size × contract unit - handling fee. If it is a positive value, it indicates a long floating profit or a short floating loss, that is, the price rise after a long position is established indicates a long floating profit, or the price rise after a short position is established indicates a short floating loss. If it is a negative value, it indicates a long floating loss or a short floating profit, that is, the price drops after a long position is established, indicating a long floating loss, or the price drops after a short position is established, indicating a short floating profit. If the margin amount is insufficient to maintain an open contract, the clearing agency will notify the meeting to make up the difference before the market opens the next day, that is, a margin call, otherwise the position will be forced to be liquidated.
