I just cannot think of other popular free website providing so much real time information on stocks, commodities for traders & investors.
One can register with them for free account & maintain the complete portfolio of stocks, mutual funds, commodities, currency trading, etc.
It has excellent user interface & I kept my self glued to it for long hours during trading.
It provides all aspects for a particular stock e.g holdings, price, volume., latest news & announcements, all technical parameters.
All in all its excellent website & anyone entering into stock market needs to start using it or start with it.
Their information panel experts are also very well known faces of Indian & Global stock market.
