Where can we get the Differential volume and Cumulative volume of a particular stocks in every 30 Mins interval, I tried to get this from Pi as well as kite, but no use.!!! Kindly help me on this, or teach me other ways to find this.

While we claim PI is far better tool than NEST in terms of features and functionalities, What refrain us to have this sort of data in PI tool, I have no Programming knowledge.! Can i expect this sort of DATA in the PI, Near Future.?

No new development will into pi in coming days, we suggest you to use kite. Also one can take chart data on to excel by right clicking on chart. You can take volume data, can use simple math functions to calculate cumulative and differential volume values by yourself.
