ASM, GSM & T2T: Why Your Stock Suddenly Gets Frozen

ASM targets unusual price/volume in normal stocks; GSM targets fishy fundamentals in penny stocks.

GSM Stage II+ adds an interest-free Additional Surveillance Deposit (ASD) of 50–100% paid by the buyer.

Trade-to-trade means compulsory delivery — no intraday, no BTST, every share must be paid in full.

GSM Stage IV can ban any upward price move and allow trading just once a week.

Check NSE/BSE surveillance lists before buying a tip stock — surveillance is the market's warning siren.
