Historical data of Nifty auto index in google finance

Hi, i need last 30 days nifty auto index data. how do I get it from google finance?

If you want EOD data then can download Bhavcopy from NSE website directly or with many free utilities available on internet.
As I know, Google dont have CNXAUTO data available, Yahoo have. If you want IEOD data, then have to use downloader such as Amiquote (free version 10 scrips max).
