The leverage ratio of foreign exchange is fixed and does not need to be calculated. Foreign exchange leverage is closely related to margin. The greater the leverage, the less margin is used for trading, and the leverage is the multiple that can be reduced.

For example, the current euro/dollar price 1.2945 has been contracted with 1. If there is no leverage (i.e. 1: 1), the fund should be 1.2945 *. If the leverage is 1: 100, the transaction can be completed with a deposit of 1294.5 USD, which is reduced by 100 times.

Margin trading usually uses leverage ranging from 1: 200 to 1: 500, and the common leverage ratio is 1: 100. At present, the leverage of foreign exchange margin trading provided by domestic banks is generally 1:25, while the leverage ratios given by domestic foreign exchange brokers are 1: 10, 1:20, 1:50,1:/kloc-0.
