For doing proper volume analysis do I need to use volume from BSE as well as NSE or only NSE would do? (since volume from BSE is shifting from BSE to NSE, would this impact analysis )?

NSE dominates BSE in terms of volumes, so I’d say only NSE should be enough. Volume analysis is also about volume trends and not really exact volumes. So NSE should be enough to track.
