Hi Mauro,
Like most new users, we often get hung up/stuck with certain trading rules that we think we can't live without it (exaggeration).
Likewise, there are many indicators in FSB Pro that can make profitable Strategies.
I've been testing many strategies for years and over the time, I come to realised that almost any or all indicators can be profitable (if you get the right settings/parameters/rules etc). Nevertheless, there are a few indicators which are my favourites and these are very common ones. Nothing spectacular about them, just knowing how to use them as deem fit is important though.
So my 2 cents worth of advise is let the software do what it is best at, look for you good indicators/parameter and then from there fine tune it further (optimization) etc to improve the results.
FSB Pro has improved tremendously over the years and recently I started to jump over to EA Studio which also produce very good strategies if you know how to refine them further (as according to you trading knowledge of how the market works).
Best of luck to your EA Development.
