    Yes, I noticed the same thing. And another app I use to download data from Yahoo (YLoader) won't work either -- it throws a "HTTP response error 301"

    Anyone else?

    I've confirmed with another software vendor the problem is with Yahoo changing their protocol: "The main fix in version 4.10 is for error 301 when downloading Yahoo data, which was due to a change in the Yahoo protocol."

    The Yahoo Historical Stock Data operator is in the Finance and Economic Data extension provided by BroadReachAnalytics. Visiting their URL provided in the RM documentation (http://www.broadreachanalytics.com/) it appears they are no longer active.

    RapidMiner: Is there any opportunity to update this operator? Thanks.

    Yes, I can confirm that this is no longer working and BroadReachAnalytics appears to be gone.

     

    With RapidMiner, you can always find a work around and here it is.

    Hi...I have moved over to "openexchangerates.com" which has a nice API. I built a simple app for an accounting client using the API on RM server. Send me a PM if you want to see it.

    Hi Thomas,

     

    Thanks for that work around. I can confirm that it works pretty well with a single symbol. However, is there also a way to load multiple symbols at a time?

     

    From your tutorials I know that it is possible to append several single symbols but in this case I want to download about 20. Searching the internet I found a site (LINK) which describes a select query but I couldn't manage to get this working in Rapidminer... :(

     

     

    Kind regards

    Hello Sachs,

     

     

    I am new for Rapidminer,

    could you please help me out in using 'xml code' for Yahoo Historical Stock price operator, which has been provided Thomas,

    using it in Rapidminer?

     

    Thanks

    Hello Thomas ... thanks for the solution. How do I implement the XML script? I copied it into the Execute Script operator and got an error (see attached). Thanks.

    Hi Sachs,

     

    Piece of cake. Just make a text file with the header Ticker and then a new symbol on each line. Then use this process below. You should save them seperately in a repository by appending %{symbol}_stock

    Hi Thomas,

     

    This already looks very promising - and brings the advantage to control stock symbols in separate external file. Pretty cool!

     

    Now I am struggling with two more problems:

    1) The process provides a collection but I rather want to have each symbol in its own column in a single example set / table.

    2) I tried to access the yahoo web api with the open file operator:

    http://ichart.finance.yahoo.com/table.csv?s=AAPL&d=4&e=10&f=2016&g=d&a=11&b=12&c=2015&ignore=table.csv

    But I couldn't manage to make the yahoo links work though they would do fine a web browser.

     

    Lookling forward to getting some advice...

     

     

    Cheers

    Sachs

    Yahoo did something to bork the whole thing recently, so I would default to Google right now. 


    With respect to putting it all in a table, I'd have to think about it but it would include using a Rename by Replacing so you can do AAPL_Close and XOM_Close and then something to merge them all together, maybe with a combination of a Remember and Recall operator but I need go AFK know.

    In times when Yahoo! Finance API is broken you can use CityFALCON's API for free.
