Hi,
I am from Ghaziabad (U.P.)
All I have to say I that for last 05 years I am trading in stocks and have tried several brokerage firms. After much of experience with brokerage house today I have found that customer care services, back-office and trading platform of ShareKhan are good and after them comes Angel and on 3rd-indiainfoline.
The worst brokerage firms are : 1st-Religare; 2nd-Nirmabang; 3rd-Indiabulls; 4th-Relaincemoney; 5th-Kotak Securities.
