Hi there!
I agree that the most of indicators lie and the moving average (and its big family) is the least liar.
There's no simple system that can make pips by crossing two EMAs, SMAs or WMAs. System means no less than 4 indicators from different categories (i.e. trend follower, overbought/oversold, volatility measuring etc) confirms each others
If you go the right direction you'll make money, don't let the crossing of 2 moving averages alone telling you the right direction even it was the right!
