religare's r-ally (diet odin) platform, allows intraday for all stocks.. beware, i lost 12k trading t2t group, which went to auction.
There is no safe heaven in trading.. if you can't profit from nifty stocks, then you can't earn with penny stocks either..
remember, it's your mind playing.. less price doesn't mean more quantity and more profit.. but it is same like big scrips.
Beware do not do intraday with any scrip ending with BE or any T2T group stock.. you'll get burnt very badly.
good luck.. experimenting is always good
