normally i dont give a damn about ma's...they're choppy and are nortorious for giving lagging signals. However through simple back testing i find that having a simple 100sma on your charts will easily divide your chart into bull/bear territory. Some of the signals that these generate are just amazing. Using sound, proper MM, this could be a real profitable system.
If you count all the possible MA look back periods, one through infinity, I guess they are an almost infinite number of "examples".
Hate to say this, but this from a guy with only 700+ posts making judgements about a guy with 400+ more posts than him is even sadder.
