Extended data:

Margin: standard.

1, the margin ratio of external futures is generally small in China, maintaining between 5%- 10%, so the leverage is slightly larger.

2. The fluctuation of external futures is smaller than that of internal futures, but it is about 10 USD.

3. Maintenance margin refers to the funds needed to maintain a position. Generally, it is about 75% of the opening margin. Take Meijing Copper as an example. If you buy two or three hands to open a position, the margin amount is 9450 USD, and the maintenance margin is 9450X75%=7087 USD.

When the position loss is less than $7,087, you will be informed of additional margin. When the position is less than half of the maintenance margin, 7087 x50% = 3543 USD (with a loss of 62.5% and unused funds of 5906.25 USD), the futures company will forcibly close the position.
