Comment on BTST/ATST( Buy/Acquire Today Sell tomorrow)
1. No, it’s considered an Intraday trade even though you’ve bought and sold in CNC. There’s no risk of penalty.
2. You’ll get the funds immediately. You can use it to make further purchases.
3. There’s still a degree of risk. If the Exchange settles your purchase through a cash credit owing to unavailability of shares, your sell trade will result in an auction. Always best to take delivery to demat and sell.
