Comment on BTST/ATST( Buy/Acquire Today Sell tomorrow)
1. Not all brokers auto square off positions. So the person who sold you 5 shares didn’t deliver to the exchange.
2. Hmm… don’t really think it is manipulation if it is for really small quantity of stocks.
3. Only for Nifty options we give leverage if you use BO or CO.
4. Yep, 25% of option writing margin or 4 times.
