>> Help: Matlab code to fetch stock price data from yahoo finance

I am a student who is getting used to Matlab.

I am trying to write a Matlab code that will goto yahoo finance, get the price of a specific stock and save it into a text file.

I am using urlread / urlwrite commands, but I have not been successful. Can anyone show me a sample script file or point me to a relevant link. Thanks in advance.

What is the URL you are trying to access?

If you have datafeed toolbox, you may try the following code.

conn = yahoo('http://download.finance.yahoo.com');
Yahoo_HSI_Data = fetch(conn,{'^HSI'},{'Adj Close'},'2012-01-01','2012-04-01','d');

You will get Hang Seng Index daily Adjusted Close Data from 2010-01-01 to 2012-04-01 . The first col is Date. And the second col is Close Price .

you may find the following link for your ref. . * http://www.mathworks.com.au/help/toolbox/datafeed/yahoo.html * http://www.mathworks.com.au/help/toolbox/datafeed/yahoo.fetch.html

To grab a single delayed quote (using Apple -- AAPL -- as an example here).

 txt=urlread('http://download.finance.yahoo.com/d/quotes.csv', 'get', ...
    {'s', 'AAPL', 'f', 'sl1d1t1c1ohgv', 'e', '.csv'} )

This return a line of text with around 10 comma-separated datum (timestamp, bid, ...). Honestly, I don't understand the magic string in the format ('f') passed to the server, but the command will fail if you omit it.

This may be enough for casual use, but serious users will want to look into MathWorks products like the Datafeed Toolbox.

Doesn't work anymore. No such Yahoo web page anymore. Any updated code that does work without special toolboxes?

Error using urlreadwrite (line 90)

The IP address of "download.finance.yahoo.com" could not

be determined.

Error in urlread (line 47)

@Image Analyst : have you made any progress on this? I have used the submission getMarketDataViaYahoo.m successfully, but I'm looking for a way to get intraday data, i.e. with a frequency on the order of minutes and not 1 day...

[Cengiz Esmersoy]

Note that in "getMarketDataViaYahoo" the AdjustedClose for ETFs are incorrect. They are not adjusted.
