For example, the international quotations for foreign exchange are all five figures. Take the euro as an example. Euro/USD is 1.2800, which means that 1 Euro can be exchanged for 1.2800 USD. The contract unit is 1K and the leverage ratio is 1: 100. So what is the margin for buying the 1 euro/dollar contract? Do the math!

1.2800 * (1*1000)/100 =12.8 USD.

How about changing the leverage ratio to 1: 400?

1.2800 * (1*1000)/400 = $3.2.

Therefore, enlarging the leverage ratio can reduce the amount of investment margin.
