Hi All,
I am regular trader via net. I have tried using porforlio of many websites like :Icicidirect, walletwatch, moneycontrol, NSEindia, economictimes.com etc..
According to me it is the best portfolio management is provided by moneycontrol. It has recently upgraded its portfolio and it is amazing.
- We get prices of both NSE and BSE simultaneously. 
- Days Price Range is provided. 
- There is facility for email alterts in case of News, Price and volume trigger. 
- The my news section provides news specific to indivisuals portfolio. 
- My messages section provides messages posted by users specific to portfolio. 
- We can track mutual funds, other assets and borrowings also. 
- We can also sort the portfolio view on different parameters. 
- In the reseach report section we can see if any new reseach report has come for the stocks in the portfolio. 
If we use moneycontrol.co.in , it is a bit faster than moneycontrol.com.
The only draw back of this site is that, it is updated after 15 minutes.
Overall the site has good content and provides a good portfolio management which inturn help in good decision making.
Thanks
-Saurabh
