Margin is the fund that investors must mortgage in order to obtain the position contract. The exchange has minimum requirements for trading members (such as futures brokerage companies), and member units (brokerage companies) will make other provisions for investors. The margin ratio is the ratio of the margin you need to mortgage to the total contract value.

Trading leverage is to enlarge the floating profit and loss ratio of account funds at the same time, which is stipulated by trading rules and is fixed. Brokerage companies cannot be changed.

The margin ratio is used to measure the amount of contract funds that can be bought and sold, and the trading leverage is used to calculate the profit and loss of account funds. They are not necessarily related to each other. The similarity between them lies in improving the utilization rate of funds and providing opportunities for ordinary investors to get involved in venture capital.
