That's not true. As for the deposit, it will be adjusted at any time. The exchange only stipulated the minimum margin. However, due to market changes, futures companies may be notified to raise prices at any time, and futures companies themselves will increase by several percentage points from the perspective of corporate customer risk. Let me give you an example. I do silver futures. The company where I open an account implements 12%, and some companies implement 15%. Because many customers have exploded positions some time ago. In order to prevent the recurrence of this systemic risk, futures companies have increased their margin on the basis of the exchange.
