Being a natural tightwad,I dont pay for data.Use free data from live.mystocks although it shows data for only 9months.You can also use bloomberg for 5yr charts....print the charts and draw trendlines using pencil and ruler,mark the resistance points,look for classic patterns etc..its faster than using clumsy software...and its fun,more of an art.
The problem with the NSE is that there is a serious shortage of research on the index...there is practically no data of more than 20yrs.
For that purpose I use the S&P500 since the performance of the NSE is very comparable and markets nowadays are intertwined.

From the charts of this contrarian we can see we are in a secular bear since 2000(IT bubble) and we'll continue till around 2017
What this means is we are in a traders market,buy and hold wont work well for the next 10yrs or so.
Just have a look at the nikkei index,20yrs later and counting and its nowhere near its high of 40000 in 1990(currently below 8000)
Blah blah blah,my two ndururus
The utimate goal of investing is to buy low sell high;if we re-write this core equation in psychology terms it becomes buy fear sell greed.
