Can I sell shares bought using CNC (or Delivery) on the same day?

You can sell shares bought using a Cash and Carry (CNC) order or Delivery order on the same day, but this trade will be treated as an intraday trade, as you are technically buying and then selling the same shares within the same trading session. Intraday Treatment - Because the purchase and sale occur in the same session, the trade is considered an intraday transaction, even though you used the CNC code.
