Dear
You have to add following sybmols
For SENSEX add " ^BSESN "
For NSE Nifty add " ^NSEI "
For NSE S&P CNX 500 " ^CRSLDX "
For NSE Nifty junior " ^NSMIDCP "
For CNX MIDCAP 200 " ^CRSMID "
FOR S&P DEFTY " ^NSED "
For BSE DX " ^BSEDX "
It will show both indices.
It does not seem to accept numerical values in the symbols
(Without quotation marks ,of course.)
Yahoo List is attached. Symbols from it can be used. If any symbol shows ??? marks means it is changed and you need to lookup here:
Yahoo Symbol Look up
and enter the correct symbol.
Alternatively you can click on the symbol in the ticker tape and it will open up the page containing information about the script. If symbol is not working you can lookup in that window .
Regards.
