It doesn’t really matter what leverage your broker is offering. I don’t think any trader would want to risk anything more than they can afford to lose. But if you are well-acquainted with risk management and money management, you can use high leverage. The maximum leverage I have used has been 1:400 with fxview and then 1:300 with Fibo Group when I was quite sure about the direction of the market. Otherwise, I keep it between 1:50 to 1:100 fearing the magnified losses.
