That's not what he meant. For example, your deposit is $3,000. With a leverage of 100, you use one thousand of your three thousand to make a move, which is a one hundred thousand order. Then the remaining two thousand is the deposit. Unfortunately, if you lose money, then you will be deducted from the two thousand dollars first. After the two thousand dollars are deducted, you will continue to be deducted from your one thousand dollars. Then, when the final percentage reaches a certain ratio, the position will be forced to close. You should have a few dozen dollars left at this point. No matter what, you cannot owe anything to the exchange, you can only lose the money you deposited.
