Third party Python API for Interactive Brokers
Latest version: 0.4.1 (TWS API v9.68)
Use pip (recommended):
$ pip install swigibpy
Alternatively download your archive of choice and run:
$ python setup.py install
Notes for Windows Users
swigibpy just provides a wrapper around the TWS C++ API so this needs to be compiled for your target platform during installation. While this should ‘just work’ for Linux and OSX, Windows users might need to do some extra work.
Compile with MinGW
Download and install MinGW and follow the steps to add MinGW to your path. Note there is a compatability problem between the latest version of MinGW and disutils so it is recommended to install an older version until this is resolved (mingw-get-inst-20110802.exe has been known to work).
To get pip to use MinGW as the compiler edit or create a file named distutils.cfg in [PYTHON LOCATION]\Lib\distutils where [PYTHON LOCATION] is the path to your Python install, e.g. C:\Python27. Add the following to distutils.cfg:
then use the pip command above and with a bit of luck, you’re done!
Alternatively you can download and build the package directly. To build and install use:
$ python setup.py build -c mingw32 $ python setup.py install
This has been verified to work using MinGW and Python 2.7 on Windows 7, Vista, and XP.
Compile with Visual Studio
Several users have reported success building swigibpy with Visual Studio, with a few caveats:
- Distutils has issues building with anything later than Visual Studio 2008 (version 9).
- Visual Studio 11 doesn’t like the /MD compile flag, which distutils adds. For a workaround see here.
To use simply import the swigibpy module. The minimum you will need to do is define an EWrapper sub-class whose methods will be invoked when a message is received from TWS, see the examples for more.
By default swigibpy will automatically poll TWS for messages, see Notes for more about this.
For API reference refer to the C++ API documentation.
The yield parameter in CommissionReport clashes with a Python reserved keyword so it is renamed to _yield.
By default swigibpy will create a background thread to automatically poll TWS for messages. If you wish to disable this behaviour and handle polling yourself use the poll_auto argument when calling eConnect:
tws.eConnect("", 7496, 42, poll_auto=False)
The TWS C++ API performs synchronous I/O using socket receive, swigibpy does not alter this behaviour (hence the background thread).
Apart from a few trivial patches to aid compilation and interoperability with Python swigibpy does not alter the TWS C++ API code in any way.
Contributions are welcome! For development you can build the extension in the current dir:
$ python setup.py build_ext --build-lib .
The majority of the swigibpy code is auto-generated by SWIG and swigibpy also includes a number of trivial patches for TWS’s C++ code. The TWS API included in the repository has already been patched and the SWIG code has already been generated, but if you need to rerun these steps the commands are:
$ python setup.py swigify
to regenerate the SWIG wrappers (SWIG 2.0+ required), and:
$ python setup.py patchify
to reapply the patches to the TWS API (specify the option -r if you want to un-apply the patches and get back to unaltered TWS code).
swigibpy original code is free software under the New BSD license.
