How can I add NSE Dataset in Wealth-Lab (Developer) Strategy?

Typically you'd use Yahoo's Classification Groups (Create New DataSet > Yahoo provider > Select from Classification Groups > World Indexes >...) Unfortunately, the choice for India and NSE just does not exist for some reason. I guess this is due to Yahoo! Finance website not listing the index constituents. Take Nifty 50, for example: it's empty.

So if you could obtain the symbols in Yahoo-compatible format (aka Reuters notation) and paste them into the New DataSet Wizard that might be the workaround. Don't forget to add applicable suffix (.BO or .NS).

On second thought, Yahoo! may not serve as a workaround. Took a few Indian stocks for example just to discover that Y! does not have the historical data for them:

https://finance.yahoo.com/quote/532555.BO/history?p=532555.BO
https://finance.yahoo.com/quote/532540.BO/history?p=532540.BO
https://finance.yahoo.com/quote/500570.BO/history?p=500570.BO
https://finance.yahoo.com/quote/500312.BO/history?p=500312.BO

This means that you probably won't be able to download the data from Yahoo.

On the bright side, Wealth-Lab paying customers should have no problem downloading NSE data using our Quandl static provider:

Free: National Stock Exchange of India
Paid: NSE premium

Like the rest of Wealth-Lab Extensions this is not available during free trial, sorry.
