Why is buying restricted for GSM stage 2 and above stocks?

Purchasing stocks in GSM stage 2 or higher is restricted due to exchange regulations. These stocks require an Additional Surveillance Deposit (ASD) equivalent to 100% or more of the trade value. The ASD margin will be blocked by the exchange for a minimum period of 2 months, even after the stock is sold.

These restrictions apply exclusively to fresh buy transactions according to our TradeJini policy. However, if you already have GSM stage 2 and above stocks in your account, you can still sell them from your holdings.
