Is the landlord talking about the crude oil futures just listed by Shanghai International Energy Center? The minimum margin of an exchange is 7 points, and general futures companies will add it on the basis of the exchange, such as 4 points or 5 points. At the same time, if you have a lot of margin and your position and risk control are well controlled, you can ask the futures company for a special margin to maximize the use of funds. It should be noted that the lower the margin, the higher your leverage will be. This is a double-edged sword.
