Hi Everyone,
NSE no longer saves the indices in a file which we can download. The only way to extract data is through there webpage via. screen scraping. The problem is most sites do not allow screen scraping so I don't think I will be making any changes to the software. If NSE in the future changes their implementation and creates a downloadable file, I am sure I would be able to make that change.
Sorry to disappoint you guys.
UPDATE:
Thanks to a comment below I was able to extract CSV file in downloadable format. I will make the changes and release a new version soon.
Thanks,
Rohit Jhunjhunwala
