Comment on Consequences of Short delivery - NSE/BSE
Amit, you should get the money on T+4 day (i.e the day after the auction).
The maximum you could lose is 20% above the closing price of stock on T+3 day. That is if the exchange can’t buy SRF in the auction market, which is the worst case scenario.
