Domestic futures trading now needs copper with a relatively large margin, and the first-hand margin is "the price at that time *5* the margin ratio". If the margin ratio is 10%, the primary margin is about15000;

There are also many gold futures deposits. The margin of gold futures is "current price * 1000* margin ratio". Generally, the margin ratio of gold in futures companies is about 15%, so the margin is about 25,000.

The margin occupation of other varieties is a little less than the above two, and the specific algorithm is "current market price * trading unit of each contract * margin ratio of this contract".
