Its very simple boss
This is the common code of yahoo
http://ichart.finance.yahoo.com/z?s=^NSEI&t=1d&l=on&z=l&q=c&p=e13,e34,e55,e233,m200,b&a=ss,r14,w14,p12&c
In this just change the symbol name of the stock, just change this ^NSEI..........
Download the yahoo symbol list and change the symbols according to yahoo database and you would get all the charts of your choice and your stock......
If you know html then add a 2 sec refresh also so as to update the prices and it wont auto update itself.......
Use the common code
Wish you good luck
