I can understand that, every1 may ask you for different topic. But, my humble request you, to share the excell sheet (data) which you refer here and how you are filling. It may sounds very silly, but u wont believe, since the video you posted, every night I need to finish the FII DII activity analysis by taking a pain killer only and having a big “zero” result. Every day I had tried to note the FII DII activity data from NSE site only(cash) and other reliable sites for derivative segment. After seeing your video (when my data has not matched) I go to NSDL site (where data update on next day- 1 day lagging); and I found (as SAD also mentioned), the Cash data is not far different from NSE.
Please help me (and us) to overcome this anomaly.
