Comment on BTST/ATST( Buy/Acquire Today Sell tomorrow)
You can use either CNC or MIS for intraday. With CNC the problem though is that you can’t short (sell first and buy back later) and you don’t get leverage. The advantage with CNC is that if you have bought something, you can hold till 3.29:59, whereas all MIS gets squared off automatically by 3.20pm.
