Futures have two deposits, one is the deposit of the futures company and the other is the deposit of the exchange. The total amount is the risk of your position. If your position exceeds the margin of the futures company, the futures company will call you to close your position, but if you have a good relationship with the account manager, this can be considered, but if it exceeds the margin of the exchange (commonly known as cross-selling), you will close your position. Generally speaking, for long-term orders, the position will not exceed 30%, and short-term overnight orders rarely exceed 70%. Under special circumstances, it may be lower, and there is no requirement for short-term days.
