the leverage of spot crude oil is the multiple of capital amplification achieved by margin trading mechanism. The greater the leverage, the greater the multiple of capital amplification, and the higher the capital utilization rate. The smaller the leverage, the smaller the multiple of capital amplification, and the relative decrease of capital utilization rate.

The margin trading system can be used to deliver electronic financial investment products of physical crude oil. Leverage refers to leveraged trading, which is used to amplify investment income (loss), reduce investment cost and improve capital utilization.
