all these vendor maintaining all different resolution data for different duration
they should maintain only 3 resolution
1sec( which they are calling tick data)
1 minute (all other resolution should be build using 1 minute data)
and then 1 day from bhavcopy
this is from truedata website
no need of maintaining 5 min /15 min/ 1 hr..instead give 1 minute for 5 months... Notice how 1 minute is only 1.5 months but 15 min for 3 months 1 Hr is 5 months this is crappy how much data bandwidth they are saving ...when will Indian trader get proper datafeed.??
I think most datafeed vendor uses these same idea..
if you are not getting 1 minute data that means you are not getting datafeed.
In this above example you are getting IEOD data for 1.5 months only rest illusion...
