Tax on share trading

Hi..

Can some one tell me the tax liability for share tradings ???

Since it is very for intraday (normally 15%), Delivery based (STCG/LTCG) and FnO tradings(Bussiness income). And the details if loss in the said categories then how it can be carry forward and set off against which incomes????

Pl suggest since there is a profit and loss in above category for me.

Thanks in advance.
