I am doing an application on financial markets that is, to buy and sell shares, etc. The problem is that I can not find a way to recover data from the actions (price, variation in%, etc.) and to update them automatically (what I've seen they recover from the national center of stock markets through of XBRL files but I do not know how to do it). I'm doing the project in .Net and javascript. something similar to this web link

javascript jquery c#

I understand that the xbrl extension has an xml format that could be parsed

XBRL wiki

If you have a url from where to download you could use the one you can use

WebClient.DownloadFile Method

You get the file and process it using Linq to Xml

Of course parsing the nodes will depend on the structure of the document.

Once you get the data you can register a db to then consume media web services you call using $.ajax of jquery

Calling ASP.Net WebMethod using jQuery AJAX

with this you can consume the parsed data from javascript

As I can analyze the link. this returns an extension file csv so the values are separated by coma

To download it use the same as before commenting the WebClient.DownloadFile() or WebClient.DownloadString() and to process the data you would use the CsvHelper

To obtain the Stock Market data you can obtain them in many ways you can obtain them by means of cvs for example:

http://finance.yahoo.com/d/quotes.csv?s=GE+PTR+MSFT&f=snd1l1yr

or

http://finance.yahoo.com/d/quotes.csv?s=AAPL+GOOG+MSFT&f=snd1l1yr

Here is an image with some claves TAGS (1letra or 1letra and 1 number, the rest is the action to request)

Image taken from google image

Example:

http://download.finance.yahoo.com/d/[NOMBREFICHERO]?s=[TICKERSYMBOL]&f=[TAGS]&e=.csv

http://finance.yahoo.com/d/[NOMBREFICHERO]?s=[TICKERSYMBOL]&f=[TAGS]&e=.csv

[FILE NAME] - Name of the file to save ("quotes.csv")

[TICKERSYMBOL] - Ticker symbol of the company (for multiple Ticker separated by commas)

[TAGS] - The stock information you request ("sl1d1t1c1ohgv" for example)

Here you can see the Market, in your comments you say the IBEX35:

link ^ IBEX

You can see the ticker symbol for each company:

About ABE.MC

http://finance.yahoo.com/d/quotes.csv?s=ABE&f=snd1l1yr&e=.csv

About ABE.MC and others add the ticker separated by , for example or by + :

http://finance.yahoo.com/d/quotes.csv?s=ABE,AMS&f=snd1l1yr&e=.csv

You can also use Yahoo Query Language , among others you can use the API:
