Selling and re-buying in CNC

Can I rebuy the CNC shares that I have sold on the same day? How does it get settled after T1 day?

Yes! You can buy the shares back in CNC and it will be considered as an intraday trade and the holding won’t be affected. ( The shares will remain there in your account )

No matter when trade, all shares will be settled after T+2 days. If you buy and sell shares using CNC on the same day, it will still be treated as an intraday trade.
