''' Provide historical ticker data for selected stocks.

This module contains five dicts: ``AAPL``, ``FB``, ``GOOG``, ``IBM``, and ``MSFT``.

Each dictionary has the structure:

.. code-block:: python

    AAPL['date']       # list of date string
    AAPL['open']       # list of float
    AAPL['high']       # list of float
    AAPL['low']        # list of float
    AAPL['close']      # list of float
    AAPL['volume']     # list of int
    AAPL['adj_close']  # list of float
