The essence of the margin level function is indeed for us to control risk by looking at the percentage of remaining margins, so that we will know the strength of our equality where, whether it still allows us to take a position or it's time we hold on and wait and see. Although the margin level does not play a direct role in account security, it is an important indicator so that we do not lose control and ignore the strength of the margin, I myself always keep the margin level below 1000%.
