Comment on Consequences of Short delivery - NSE/BSE
First of all i am a normal zerodha customer and not associated with zerodha
if u sell from demat account say 100 shares of XXX
and but 100 shares of XXX on the same day
it will have zero effect on the number of shares of demat
the calculation i guess for transfer of stocks happens at the end of the day so at the end neither u have bought nor sold your shares to anyone
so if your demat has 1000 shares of XXX
it will still have 1000 shares of XXX
and yes u can still safely sell your shares the next day
given u are selling under 1000 shares of XXX
cheers
