hey i bought a stock, the day it got listed in the market, it got listed at rs. 375 , issue price was rs. 175 and i bought it at 457, at the end of the day it was 552.now i wanted to get out of it the next day, but as it was not included in the BTST segment i couldn't, now when i hear the news and all, they say day traders buy it and sell it the same day and all, now how can i do that ? i mean until the stock has been credited to my demat account, how can i sell it?
