It is a part of the SATYAM Portal where you can manage your different portfolios and it updates the script value on line and gives you the actual value with % gain/loss , MKt value Purchase value which you can customise as you wish. It even gives you graphs on your script.
It even gives you good intra day/3 monthly/6 monthy /annually chart movements.
The only problem with this site is it updates its prices only after 15/20 mins. you dont get a clear picture at a given point of time for this purpose ICICI direct but it only gives you prices from NSE. and you can not concentrate on multiple scripts at ICICIdirect.com
At the end it is a good site if you want to analyse at the end of day not in the trading time.
