Yahoo Finance¶

class pandas_datareader.yahoo.daily.YahooDailyReader(symbols=None, start=None, end=None, retry_count=3, pause=0.1, session=None, adjust_price=False, ret_index=False, chunksize=1, interval='d', get_actions=False, adjust_dividends=True)¶

Returns DataFrame of with historical over date range, start to end. To avoid being penalized by Yahoo! Finance servers, pauses between downloading ‘chunks’ of symbols can be specified.

Parameters

symbols (string, array-like object (list, tuple, Series), or DataFrame) – Single stock symbol (ticker), array-like object of symbols or DataFrame with index containing stock symbols.
start (string, int, date, datetime, Timestamp) – Starting date. Parses many different kind of date representations (e.g., ‘JAN-01-2010’, ‘1/1/10’, ‘Jan, 1, 1980’). Defaults to 5 years before current date.
end (string, int, date, datetime, Timestamp) – Ending date
retry_count (int, default 3) – Number of times to retry query request.
pause (int, default 0.1) – Time, in seconds, to pause between consecutive queries of chunks. If single value given for symbol, represents the pause between retries.
session (Session, default None) – requests.sessions.Session instance to be used. Passing a session is an advanced usage and you must set any required headers in the session directly.
adjust_price (bool, default False) – If True, adjusts all prices in hist_data (‘Open’, ‘High’, ‘Low’, ‘Close’) based on ‘Adj Close’ price. Adds ‘Adj_Ratio’ column and drops ‘Adj Close’.
ret_index (bool, default False) – If True, includes a simple return index ‘Ret_Index’ in hist_data.
chunksize (int, default 25) – Number of symbols to download consecutively before intiating pause.
interval (string, default 'd') – Time interval code, valid values are ‘d’ for daily, ‘w’ for weekly, ‘m’ for monthly.
get_actions (bool, default False) – If True, adds Dividend and Split columns to dataframe.
adjust_dividends (bool, default true) – If True, adjusts dividends for splits.

class pandas_datareader.yahoo.options.Options(symbol, session=None)¶

*Experimental* This class fetches call/put data for a given stock/expiry month.

It is instantiated with a string representing the ticker symbol.

The class has the following methods:: get_options_data(month, year, expiry) get_call_data(month, year, expiry) get_put_data(month, year, expiry) get_near_stock_price(opt_frame, above_below) get_all_data(call, put) get_forward_data(months, call, put) (deprecated)

Examples

# Instantiate object with ticker >>> aapl = Options(‘aapl’)

# Fetch next expiry call data >>> calls = aapl.get_call_data()

# Can now access aapl.calls instance variable >>> aapl.calls

# Fetch next expiry put data >>> puts = aapl.get_put_data()

# Can now access aapl.puts instance variable >>> aapl.puts

# cut down the call data to be 3 below and 3 above the stock price. >>> cut_calls = aapl.get_near_stock_price(call=True, above_below=3)

# Fetch call and put data with expiry from now to 8 months out >>> forward_data = aapl.get_forward_data(8, call=True, put=True)

# Fetch all call and put data >>> all_data = aapl.get_all_data()

close()¶: Close network session
