Hello oceanmen, thanks for your comment.
Can you be more specific about (10% a year is not bad at all vs the risk free rate)… you mean, if I win 10% it´s good? The thing is that I get commissions each trade I put, and the result for my clients is apart, no matter if the trade won or lost, I mean I can get 3% of the account on commissions, and the result for the client is apart, could be -10% of his capital or 7% won
