AllyInvest.py

A blackbox Ally Invest/TradeKing API interface for application developers.

AllyInvest.py is a part of the PyPi repository and can be installed via

  pip install AllyInvestPy

AllyAPI.py A Python3 class that allows access to all of the functionality in the Ally/TradeKing API.

This package attempts to stay on top of changes to the API and allow an easy to user interface with the Ally Invest API. The API does no formatting for the user. A response format of 'xml' or 'json' can be specified and the API responses will be returned as the raw XML or JSON, respectively.

This API was built with the developer in mind and should allow a developer to build applications around the Ally Invest API without having to deal with accessing and managing the requests and responses.

Documentation

Doxygen was used to generate documentation for this interface. The generated documentation can be found here.

Perhaps the most useful documentation is of the AllyAPI class as this documentation shows which functionality is available and describes how to use each function.

Usage

Details coming soon. Some basic usage can be found in example.py until then.

TODO

• Documentation
  • URLs.py and examples.py
• Implement missing functionality
  • Right now, the API implements many of the calls listed on Ally's documentation page but there are many not yet implemented (due to time constraints). Below is a list.
  • Adding the functionality is pretty straight forward, some more details are below.
• Test
  • Everything
  • Add unit tests

Adding New API Functionality

To add a new API function the API URL has to be added to the URLs class in URLs.py. Note that the request endpoint is already stored in the class e.g.

https://api.tradeking.com/v1/

Therefore, only anything after /v1/ needs to be added as a URL. A method to obtain the full URL must be implemented as well, examples abound in the URLs class.

After the URL is added, implementing the POST or GET is very simple. There are two private methods in the AllyAPI class that allow easily retrieving data provided only the URL. these are __get_data(self, url) and __to_format(self, response).

To add the new functionality, just create a method call in the AllyAPI class that uses your new URL and returns/calls the __get_date(...) method. This will return the raw XML or JSON response from the user depending on the format set up when creating the AllyAPI class instance.
