I have had sold 400 Kwality Dairy Equity Shares on cash market on 30.4.2012.Till date and time (3.05.2012 18.45 hrs) the money has not been credited to my S.B account.Yesterday when I contacted my HDFC SECURITIES broker for buying DCB stock option he said only on realisation of cash which I have had sold from Kwality dairy is realised I can make the transaction on options .Since 4 days I am sitting idle viewing the stock in my system without doing any trade.Can you explain?
