Useful Resources

Portfolio Management:
I was using ICICI Direct (www.icicidirect.com) for my portfolio management which comes as part of the account. And it lack even the basic functionality. It is really poor for portfolio managment and tracking.

Recently I came across www.moneycontrol.com 's portfolio management, it is free and its great!! I love it. Also, they provide a consolidated view of all the news, messages related to the companies in portfolio.

Charting:
Yahoo India finance's (http://finance.yahoo.co.in) charting is good. They provide easy charting, comparision to sensex and upto 3 companies in same chart.

www.economictimes.com also have easy charting, but offer no comparision.

Research & Analisys:
Quots & ratios from moneycontrol and icicidirect.
Economictimes also provides helps.

Stock Screening:
www.icicidirect.com provides couple of predefined stock screenings and a basic custom screening tool.
