FinancialData["IndiaNSE", "Members"] // Shallow

gives

{"^CNXIT", "^CRSLDX", "^CRSMID", "NS:20MICRONS", "NS:3IINFOTEC", \
"NS:3MINDIA", "NS:526015", "NS:AARTIDRUG", "NS:AARTIIND", \
"NS:AARVEEDEN", <<1432>>}

But when I query

FinancialData["NS:20MICRONS"]

I get the following error

 FinancialData::notent: NS:20MICRONS is not a known entity, class, or tag for
  FinancialData. Use FinancialData[] for a list of entities. >>

Interestingly I tried the same query on Wolfram Alpha http://www.wolframalpha.com/input/?i=FinancialData[%22NS%3A20MICRONS%22]

I got this Assuming 20MICRONS | Use 533022 instead

I tried

FinancialData["MB:533022"]

and I got the same error!

Is this expected ?

    $\begingroup$ It appears to be a bug. I am a Brazilian, and I am able to access Brazilian data. As one of the datasources for FinancialData is finance.yahoo.com and beyond that, the exchanges are abbreviated as Yahoo abbreviate them, I used to believe that if you can access this address finance.yahoo.com/q?s=20MICRONS.NS then FinancialData should report a valid answer for FinancialData["NS:20MICRONS"]. Take a look at this question mathematica.stackexchange.com/questions/16944/… $\endgroup$ – Ailton Andrade de Oliveira Aug 6 '13 at 21:22
  • $\begingroup$ bug - hmm! I looked at the link provided above. Sounds like the support must have been discontinued. I tried using 20MICRONS.NS - it does not work $\endgroup$ – ram Aug 6 '13 at 22:51

    $\begingroup$ Also found this link http://mathematica.stackexchange.com/questions/9540/problem-with-financial-data where the data was not working since its source (Yahoo) discontinued to support $\endgroup$ – ram Aug 6 '13 at 22:55
  • $\begingroup$ My bad. @ram got it right. I am only adding another link that could be included in Mathematica documentation as well. It is a list from Yahoo! of the exchanges and the data Yahoo! can provide. help.yahoo.com/kb/… Here you can see that for National Stock Exchange of India the data are only real-time and for signed in users. $\endgroup$ – Ailton Andrade de Oliveira Aug 7 '13 at 2:52
  • $\begingroup$ Vitaly Kaurov's answer to the question you linked works if you substitute "NS:20MICRONS price history" for "^DJI price history". $\endgroup$ – Michael E2 Aug 7 '13 at 11:00
