Datafeed Toolbox does not work with Yahoo

I am trying to connect to Yahoo Finance with the Datafeed Toolbox, but I obtain the following error:

>> c = yahoo

 Error:
 Error using yahoo
 Unable to connect or retrieve data from given URL.

>> fetch(yConnect,’AAPL’) % generates an error

 >> fetch(yahoo,'%5EGSPC',{'Last'})  % either returns empty or generates an error
 Error using urlreadwrite (line 98)

 retdat = urlread(fetchurl);

 tmpdat = wwwread(fetchurl,numinputs);

 

>> fetch(yahoo,'%5EGSPC',{'close'}, today - 30,today-1)

I've followed the instructions and replaced the files.

>> yahoo;

>> fetch(yahoo,'ibm');

Now works but fetching historical data still gives me error...

>> fetch(yahoo,'ibm','close',today-30,today-1);

Error using yahoo/fetch (line 387)

Unable to return historical data for given security.

Please help, thanks!

I have the same exact problem, can get current data but cannot get historical data between dates. My Matlab is already applied the workaround.

[Xander Mann]

I have the same issue. It was working fine last night, but now it's not pulling anything...

[Octavio Garcia]

Same problem here downloading historical data using urlread, 12h ago was ok......Yahoo has changed something again.

[Ashot Nanyan]

I have exactly the same problem. And Little time till my deadline. What would you advice me? Thank You!

[Alex Layten]

I'm also having this issue (line 387). Hopefully they have a solution for this soon.

[Vittorio]

Same here... working well until 1.5 days ago and yesterday it did not... did anybody figured out a work around?!

[Octavio Garcia]

These are the 2 link about the Yahoo API related to this problem. I hope they will be wrong and exist someone in YAHOO that put this service back.....but looks like no more intelligent life in Yahoo.

I found some logic in the new URL to download the historical data; see code below. The problem I am facing now is when I use the command URLREAD. If I copy and paste the created url string on the browser, the CVS is automatically downloaded but when I do it in MatLab with URLREAD then I get an error like MatLab not being connected to the web. Any help?!

date_ref=datenum('18.05.2017','dd.mm.yyyy'); date_start=datenum(date_start,'dd.mm.yyyy'); date_end=datenum(date_end,'dd.mm.yyyy');

date_ref_yahoo=1495058400; date_start_yahoo=date_ref_yahoo+(date_start-date_ref)*86400; date_end_yahoo=date_ref_yahoo+(date_end-date_ref)*86400;

url_string=['https://query1.finance.yahoo.com/v7/finance/download/' stock_symbol '?period1=' int2str(date_start_yahoo) '&period2=' int2str(date_end_yahoo) '&interval=1d&events=history&crumb=STV4YWMVtSO'];

url_string

[str,status] = urlread(char(url_string))

[Octavio Garcia]

I tried with urlread2, and this is the result:

date_start='18.04.2017'; date_end='18.05.2017'; stock_symbol='A'; date_ref=datenum('18.05.2017','dd.mm.yyyy'); date_start=datenum(date_start,'dd.mm.yyyy'); date_end=datenum(date_end,'dd.mm.yyyy');

date_ref_yahoo=1495058400; date_start_yahoo=date_ref_yahoo+(date_start-date_ref)*86400; date_end_yahoo=date_ref_yahoo+(date_end-date_ref)*86400;

url_string=['https://query1.finance.yahoo.com/v7/finance/download/' stock_symbol '?period1=' int2str(date_start_yahoo) '&period2=' int2str(date_end_yahoo) '&interval=1d&events=history&crumb=STV4YWMVtSO'];

url_string

[str,status] = urlread2.urlread2(url_string)

and I obteined:

status =

      allHeaders: [1x1 struct]
    firstHeaders: [1x1 struct]
          status: [1x1 struct]
             url: [1x137 char]
          isGood: 0

Im not an expert.....sorry about that

[Octavio Garcia]

str =

{ "finance": { "error": { "code": "Unauthorized", "description": "Invalid cookie" } } }

For those who have active accounts with TD Ameritrade / Thinkorswim, I have a solution to this problem. This involves use of a Matlab toolbox I developed so it can be considered a solicitation. Therefore, if you want to know more then just send me an email and we can discuss through other channels.

[Victor Hatman]

I implemented the fix (I am using R2017a), and it does not work for historical data. It only works for current data:

>> fetch(yahoo,'IBM')

ans =

struct with fields:

    Symbol: {'IBM'}
      Last: 152.6400
      Date: 736837
      Time: 0.6681
    Change: 0.6600
      Open: 152.1000
      High: 152.8400
       Low: 151.6000
    Volume: 3302539

But when I try for historical data I get an error:

>> fetch(yahoo,'IBM','02/01/2017','03/20/2017')

Error using yahoo/fetch (line 387)

Unable to return historical data for given security.

I hope your fix work and can be shared to the community in the File Exchange. Not historical but is something
