Leverage, can someone explain it to me?

You need to be careful with leverage - yes you win more, but your losses get magnified also.

By using leverage you will be win or not , it depends on your trading plan . With real trading plan including exact risk managing plan it is obviously possible to make profit very quickly by using high leverage despite of having small balance. on the other hand , in spite of sufficient trading balance that’s not possible to ensure profit by leverage , if you don’t know how to manage risk.

With minor trading equity it is quite risky to use high leverage as like 80% risk 20% chance to make sure profit. so I don’t think so by using high leverage with small balance is a mature trading activity.
