there seems to be difference in calculation by afl or by the data provider
this is your chart
this is my chart
as you can see in your chart there is a complete buy set up but in my chart the buy setup never occurred... i am afraid this is mostly due to price differences...
i think a little labor work is required from both of us...
i would request you to check the your data with nse if you find any wrong data than please post and the same i will do with my data and post abt any wrong data from my end...
this way we can mark which days data are wrong... this will also evaluate our data providers reliability....
