Great site
I wanted to post a question at your site - but could not find where to do so. Anyhow my question is - on backtesting I get 'profit factor' and 'profit' - now the most profitable results seldom have the highest profit factor. I guess one just has to choose parameters somewhere between between the two - and hope for the best.
I believe the higher profit ones where just luckier. I don't know. If you could discuss this in one of your articles it would be great. I attach the current results for my optimize test on ema_cross on the USDJPy daily
