YAHOO......
Today I have observed that yahoo finance is automatically updating quotes and charts. No need to have any software. Just log on to yahoo finance web site, give ticker code of your favourite stock and leave the web page alone and sit back and observe. All data (such as bid price, ask price, last traded price, high low for the day, volume etc. are updated automatically. This is not all. Even the chart is also updated automatically. Earlier, I had to refresh web page every time, if I had to get the latest quotes. At least in cash market of BSE and NSE now we can have live quotes and charts. A great relief to all those who do not have paid software and costly data services.
I once again say YAHOO
