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(2014,1,1)
end = datetime(2018,2,5)
ret = pdr.get_data_google(['FB'], start, end)
