I am not able to understand how Leverage works some of my questions below
1. Why a broker gives Leverage, whatís his profit?
2. They say by 1:100 you can purchase 100 USD by having 1 USD, if I am in 1:500 then I can purchase 500 USD by using 1 USD? So if I purchase 4 Lots is Margin used will be different then 1:100 to 1:500?
