For example, the price of a ton of copper is 70,000 yuan, and it needs 350,000 yuan in one hand, which is calculated according to the margin ratio of 10%.

In this way, the capital needed for futures trading of primary copper is 35,000.

If the profit of copper is 1000 points, then the profit of this copper is 5000 yuan.

The yield is 5000/35000= 14.2857%, and you will find that the yield is surprisingly high. This is the leverage of futures, which not only enlarges the funds, but also enlarges the income.

Essentially, the yield is 5000/350000= 1.42857%.
