The position ratio is the ratio of the margin used for holding the contract to the total amount of funds in your account. There is no inevitable situation that the sum of space and time is 100%. If there is, it is also a coincidence. For example, multiple positions account for 70%, and empty positions account for 30%. The position ratio can be controlled by yourself. The smaller the proportion of positions, the smaller the risks and benefits. On the contrary, the bigger.
