As per above, but also what purpose are you using MA for? Investment in long term portfolio=MA usually pretty useless, Short term trading then you MA=you time frame.....ie if you intraday you are not gonna use a 200 and I doubt you will even use a 50. I use a 14 or 26 and even cut it to 10 on very short trades. MA however is not the best indicator for me. I use it with MFI/RSI plus STO & ROM. Volume and DMI (ADX) and MACD used in some cases to look at trend and volumes but not to often. So as you see it really has to do with your time frame and what your outcome expectation is. As they say exist stratergy is far more improtant than entry.
