Hi,
For those who r concentrating on MA (EMA/ SMA etc),plz try to adopt some kind of adaptive MA (plz refer Karthik's thread).MACD is also on same catagory.1.5 yrs back i found Nifty was following 13 EMA ,few weeks back ,found Nifty has a cycle of 26 trading session.Half cycle (13) is always Analyst's have try to follow.
As u r concentrating on MA ,plz adopt some type of "Adaptive" type ,so when the cycle changes,you dont have to optimize again for the period.
My conception for MA is that :- it is most simplest way to state TREND,as i belive MACD or RMO will keep you on the right side of the mkt.
Cheers
