[BUG] Yahoo duplicate row

[okomarov]

I am on 0.7.0 pdr:

pdr.get_data_yahoo('AMZN', start='2019-01-25', end='2019-01-26')

where 2019-01-26 is a Saturday.

This outputs:

                   High          Low    Open        Close   Volume    Adj Close
Date
2019-01-25  1683.449951  1662.000000  1670.5  1670.569946  4959679  1670.569946
2019-01-25  1683.479980  1661.609985  1670.5  1670.569946  4945900  1670.569946

It should only return the last row.

This seems to be an issue with yahoo itself.

Querying same day, returns nothing:

Querying Friday to Sunday returns the two rows listed above:

and params for the GET request are:

name	value
formatted	true
crumb	plThqsOcXUi
lang	en-US
region	US
period1	1548374400
period2	1548547200
interval	1d
events	div|split
corsDomain	finance.yahoo.com

Workaround

Drop first as df is in ascending order while yahoo web page lists in descending :

df = df[~df.index.duplicated(keep='last')]

Reported bug on Yahoo forums as well.
