For example, if there is only 6.5438+million in your account, then you buy a contract with 6.5438+million, and your trading margin needs 6.5438+million yuan according to the margin ratio of 654.38+ 00%, then the settlement reserve is zero at this time.

The next day, the contract value becomes 6.5438+0.2 million yuan, that is, you have made a profit of 200,000 yuan. After the settlement of the exchange, 200,000 yuan will be credited to your account from other loss-making accounts. At this time, if you haven't opened a position, according to the ratio of 654.38+00%, the trading margin needs 6.5438 +0.2 million yuan, compared with the original 6.5438+0.2 million yuan, so your settlement reserve is still 6.5448+0.00 million yuan.

I don't know if you understand.
