Under what circumstances do customers need to add margin for investment futures? Please make it clear before filing a case.
Futures is a risk rate. Different futures companies set different risk rates. Generally, when the futures risk rate is 100%, the system will prompt for additional margin. When the risk rate is lower than 70%, the system will automatically close the position. The risk rate is the ratio of the customer's floating net value to the position margin. For example, if the customer has 200,000, then if he has 20,000 in one hand, he will make 8 lots, and then he will account for160,000. If you don't understand anything, you can ask me.
