Live advance decline chart for NSE and index contribution of nifty and bank nifty

thank you for your reply neha… But these sources are free and i have had experienced certain issues with them like they don’t get updated at times/ don’t give realtime info… LIke sharekhan is 10-15 minutes delayed… motilal oswal’s page gets updated on its whims…

what to do? any broker who provides this info?
