I'm with ya Clay on the 5-SMA, 10-SMA, 20-SMA, 50-SMA and 200-SMA, but I've read charts being quoted as, 87 SMA, 93 SMA, and so on which I have never followed.
Oh ayes I agree there are universal averages, and the 50 and 200 are certainly standards, and te 10 and 20 maybe very useful for short term trading no doubt. My BS meter starts to go off when I read a professorial diatribe hitch includes the 84 and the 35 day morning averages! LOL
