Temporary fix for Pandas Datareader's get_data_yahoo()

Project description

Yahoo! Finance Fix for Pandas Datareader

Python version Travis-CI build status PyPi version PyPi status Star this repo Follow me on twitter

Yahoo! finance has decommissioned their historical data API, causing many programs that relied on it to stop working.

fix-yahoo-finance offers a temporary fix to the problem by scraping the data from Yahoo! finance using and return a Pandas DataFrame/Panel in the same format as pandas_datareader’s get_data_yahoo().

By basically “hijacking” pandas_datareader.data.get_data_yahoo() method, fix-yahoo-finance’s implantation is easy and only requires to import fix_yahoo_finance into your code.

Quick Start

from pandas_datareader import data as pdr
import fix_yahoo_finance  # <== that's all it takes :-)

# download dataframe
data = pdr.get_data_yahoo("SPY", start="2017-01-01", end="2017-04-30")

# download Panel
data = pdr.get_data_yahoo(["SPY", "IWM"], start="2017-01-01", end="2017-04-30")

I’ve also added some options to make life easier :)

Below is the full list of acceptable parameters:

data = pdr.get_data_yahoo(
            # tickers list (single tickers accepts a string as well)
            tickers = ["SPY", "IWM", "..."],

            # start date (YYYY-MM-DD / datetime.datetime object)
            # (optional, defaults is 1950-01-01)
            start = "2017-01-01",

            # end date (YYYY-MM-DD / datetime.datetime object)
            # (optional, defaults is Today)
            end = "2017-04-30",

            # return a multi-index dataframe
            # (optional, default is Panel, which is deprecated)
            as_panel = False,

            # group by ticker (to access via data['SPY'])
            # (optional, default is 'column')
            group_by = 'ticker',

            # adjust all OHLC automatically
            # (optional, default is False)
            auto_adjust = True,

            # download dividend + stock splits data
            # (optional, default is None)
            # options are:
            #   - True (returns history + actions)
            #   - 'only' (actions only)
            actions = True,

            # How may threads to use?
            threads = 10
        )

It can also be used as a stand-alone library (without pandas_datareader) if you want:

import fix_yahoo_finance as yf
data = yf.download("SPY", start="2017-01-01", end="2017-04-30")

Installation

Install fix_yahoo_finance using pip:

$ pip install fix_yahoo_finance --upgrade --no-cache-dir

Requirements

Optional (if you want to use pandas_datareader)

P.S.

Please drop me an note with any feedback you have.
