Hi,
again, as someone else, I'd like to steer clear of forums. However, as for someone else, such sort of posts are a too strong push!

What do you consider such backtest result (two months about the 1 minute TF):



Then, please, go to this link:

and examine it, repliing, until you're very comfortable with it.

If you're already very familiar with all that stuff (i.e. you know how many ways you have to create illusions from backtesting), I sincerely apologize, and your chart might begin to have some real interest. Otherwise, it can be whatever : curve fitting, exploiting unrealistic spreads, bad information, lack of statistical significance... anything. There are 1000 means of generating impressive charts with a backtest. And this is exactly what normally commercial EA sellers perform.

Sorry to be a bit crude.

Bye
