That's not what he meant. For example, your investment is 3000 dollars. 100 lever, you made a single hand with one thousand of your three thousand, which is a list of one hundred thousand. Then the remaining two thousand is the deposit. It's a pity that you lost money. First deduct it from this 2000 Li, then continue to deduct this 1000 after deducting this 2000 Li, and then force the liquidation to a certain proportion. At this time, you should still have dozens of dollars. In any case, you can't owe the exchange, you can only pay for the money you invested.
