Unable to fetch Google finance data

[nasirali1]

Google has changed their URL from "http://www.google.com/finance/info" to "https://finance.google.com/finance"

[rsvp]

OK, please tell us if and where this breaks the API.

What are the error messages with respect to pandas-datareader?

• Follow-up in near-duplicate issue It seems that Google does no longer provide historical stock data? #391

Hi rsvp,
Thanks for a prompt reply. Please find below the python code and error trace:

Maybe it makes sense to contact Google to ask for a correction, but I do not think that the issue affects only a few.

[nasirali1]

paindog, Google has changed/restructured their finance urls. It's not a mistake that we can ask Google to fix.

[paintdog]

They reduced the available data to the period of about one year. That's a problem they could fix...

[nasirali1]

paintdog, I think, this is a simple URL update in pandas-datareader API. Current URL used in api is "http://www.google.com/finance/info". This URL should be updated to new Google finance URL: "https://finance.google.com/finance".

API code snippet (data.py)
class GoogleQuotesReader(_BaseReader):

"""Get current google quote"""

@property
def url(self):
    return 'http://www.google.com/finance/info'

[minimalgeek]

Temporary and very ugly solution for testing purposes:

from pandas_datareader.google.daily import GoogleDailyReader

@property
def url(self):
    return 'http://finance.google.com/finance/historical'

GoogleDailyReader.url = url

# get data

import pandas_datareader as pdr
from datetime import datetime

start = datetime(2010,1,1)
end = datetime(2014,1,1)
ret = pdr.get_data_google(['AAPL'], start, end)

[sof]

Changing the URL works, but the 302 redirect that www.google.com/finance/historical returns will currently strip the startdate= and enddate= params, which is why people are seeing only the past year's data being returned.

Unintentional bug in the www.google.com redirect rule at play?

[TyrelCB]

the commit added by soon fixed the historical collection, however the delayed quote is still not functional, I've tried http://finance.google.com/finance with no success

[rsvp]

@TyrelCB The latest PR by @soon has failed Travis build: #402

Google Finance under renovation, portfolios to be deprecated mid-November 2017 : rsvp/fecon235#7 (comment)

[coulanuk]

This fix may be a waste of effort. It looks like there are big holes in the underlying datasets on Google Finance, eg Bank of America (BAC) or JP Morgan (JPM) have nothing or garbage prices (as of the date I am posting).

Fixed in #404.
