If the position amount of today's transaction is the same as the settlement price of today. Then the balance of the deposit is the balance after deducting the settlement reserve from your account balance.
If the transaction price of your day is greater than the settlement price of that day, then add the margin to the difference between the two prices. Is the balance of your settlement reserve. On the other hand, if the position price (cost) of the day's transaction is lower than the settlement price of the day, the difference between the two should also be subtracted.
How is it calculated? You can see it on this website:/n575458/n870586/n1335340/n3140056/10423209.html.
Excerpted from the "Question and Answer of Stock Index Futures" in the Detailed Rules for Settlement of China Financial Futures Exchange compiled by China Financial Futures Exchange, the specific calculation formula of the balance of the provision for settlement on that day is as follows:
Balance of settlement reserve for the current day = balance of settlement reserve for the previous trading day+trading deposit for the previous trading day-trading deposit for the current day+profit and loss for the current day+deposit and withdrawal-handling fee, etc.
After settlement, when the balance of the settlement reserve of the settlement member is lower than the minimum balance standard, the settlement result is regarded as the notice of additional margin issued by the exchange to the settlement member, and the difference between them is the amount of additional margin.
After issuing the notice of additional margin, the Exchange may deduct it from the special fund account of the clearing member through the depository bank of futures margin. If the full deduction is unsuccessful, the settlement member must make up the minimum balance of the settlement reserve before the market opens on the next trading day. If the balance of settlement reserve is lower than the minimum balance of settlement reserve, the position shall not be opened; If the balance of settlement reserve is less than zero, the exchange will handle it in accordance with the provisions of the risk control management measures.
