Zabeen, I have used 20 MA in different TF and find it to be useful. After a trending move, the 1st and the 2nd touch to the upward sloping MA's are a buy (reverse for short) Sonic too uses MA's and hence my interest in following this thread/system. I find that if smaller TF in agreement of higher TF, it is a good way to trade. We can have our own rules for the same... which may vary from trader to trader. My 2C.
