The leverage ratio in the forex exchange market is simply the controllable ratio of your funds. Forex exchange margin trading does not require full payment. You only need to pay a certain margin and you can control an equal proportion of funds. For example, when the leverage ratio is set at 1:100, you only need 10,000 USD and you can control 1 million of funds, but it is only virtual, not cash, which means that you have to bear the 1 million currency you bought The risk of loss, on the contrary, if you make a profit, you can earn the profit of that 1 million.
