Let’s say I have zero balance/funds in my account and I sell 100 shares from my holding from demat. As long as I don’t use selling credit for any other trades and just buyback the same holding - same qty- 100 shares - it will be just traded as intraday trade correct?- can there be any possibility of margin penalty in such case? I repeat I won’t use selling credit for anything other than squaring off(buy back same shares)
