Wallstreet: Real time Stock and Option tools

Wallstreet is a Python 3 library for monitoring and analyzing real time Stock and Option data. Quotes are provided from the Google Finance API. Wallstreet requires minimal input from the user, it uses available online data to calculate option greeks and even scrapes the US Treasury website to get the current risk free rate.

Usage

.. code-block:: Python

from wallstreet import Stock, Call, Put

s = Stock('AAPL') s.price 96.44 s.price 96.48 s.change -0.35 s.last_trade '21 Jan 2016 13:32:12'

Options:

.. code-block:: Python

g = Call('GOOG', d=12, m=2, y=2016, strike=700) g.price 38.2 g.implied_volatility() 0.49222968442691889 g.delta() 0.56522039722040063 g.vega() 0.685034827159825 g.underlying.price 706.59

or

.. code-block:: Python

g = Put("GOOG") 'No options listed for given date, using 22-01-2016 instead' g.expirations ['22-01-2016', '29-01-2016', '05-02-2016', '12-02-2016', '19-02-2016', '26-02-2016', '04-03-2016', ...] g Put(ticker=GOOG, expiration='22-01-2016')
