Since this thread got picked up again, I'll point out that if one wants to know the truth, he'll have no choice but to test his assumptions before putting any real money on the line. By doing so, he may avoid some unpleasant surprises, such as will likely occur if he enters/exits via the usual suspects: RSI, MACD, %R, CCI, etc, etc, etc.
One also must decide just what it is he wants the indicators for. If they are to be used for scanning, and one wants to know about trend changes, simple MAs are a proxy for trendlines (since they are, after all, just moving trendlines) and are easy to use for scans ("easy" as compared to trendlines).
Demand/Supply
Price/Volume
Support/Resistance
Trend/Oscillation
That's it.
