I want to who is selling/buying the stocks?
FII/DII - There name and there action. For Example On 30th April 2018, PCJ is traded heavy volume( above 10 days average Volume).
Curious to know who are actually selling the stock.
these details can be found in bulk deals only and some web pages also take data from them and show, but when no buyer/seller trades in bulk, you cannot find their names except they release that themselves.
for bulk and block deals go to report section in nseindia website, direct from exchange.
and for numbers of large deals search large deals and choose moneycontrol
