I thought I would jump into the fray on this one...
I recently bought FAPT based on the enormous amount of affiliate sites. Some people were showing tremendous results, so it must be a decent system, right?
Well, not exactly. My FXCBS demo account had a large amount of open losing trades. This was so large at one point the demo account almost had a margin call (so to speak). All of the open trades are on the EURUSD pair.
Based on my research, emails, etc, you need to constantly modify the settings to get good results. I'm still not sold on this one, but it does have potential to get good returns, as long as you have the correct settings. Otherwise, you will probably pull your hair out trying to duplicate the results with demo account and back tests.
If ANYONE knows of a reputable site which has good quality settings that don't cost $$$, please let me know.
