Additional margin for futures, assuming that the initial investment is 654.38+0 million, and the margin rate is 654.38+00%. The futures company asked me to increase the margin when the decline was what. This depends on how much you have. Examples are as follows:

1, 1 10,000 to buy futures in full, so long as it falls a little, it is necessary to add margin. Otherwise, the futures company will force the liquidation.

2. If you buy 500,000 futures, you will explode your position if you fall by 20%, so you need to add margin before you fall by 20%, otherwise you will be forced to close your position.

And so on.
