I have my own very profitable EA thanks. Unfortunately i cannot sell it on as it is in my brain. The method has been engrained in it, as a result of more hours than i would care to mention sat at this bloody computer!
It works well, though not all the time, the rules are fairly rigid, though still subject to change and my user discretion.
I do not believe that your "scalping" EA is real, or that it can work. The markets, escpecially for when "scalping" are just not robotic like that, especially when trading with MT4 broker sized wide spreads. I wish the markets were more robotic, then trading would be a piece of ****!
