You should be talking about an explosion. For example, if your principal is 10000 yuan, you will take up the deposit of 1000 yuan when you buy primary oil. If the direction is wrong, you will lose 9000 first. When the loss of 9000 yuan ends, the loss will account for 70%-50% of the deposit of 1000 yuan. Among them, 70% to 50% is called risk rate. I just want to make the example clearer. The trading rules of each trading platform are different, but there is little difference.
