First of all thanks for sharing valuable knowledge. In the Insider trading excel sheet downloaded from https://www.nseindia.com/companies-listing/corporate-filings-insider-trading, I choose 3M and download as advised in video. When I open this excel sheet there is a column “DATE OF ALLOTMENT/ACQUISITION FROM” there are data which is older than 3 months, do we need to delete and retain ONLY 3 months, apologies if this was explained in the videos and I missed to understand.
Thanks for your efforts again.
