API Trading

Supported Languages and Technologies

Our propriety API allows traders to build their own automated rules-based trading application in Java, C++, C#, Python or DDE.

First, download the API software from our GitHub repository: http://interactivebrokers.github.io/. Furthermore, developers interested in collaborating can find instructions on how to contribute and commit code on our GitHub page: http://interactivebrokers.github.io/api_software_contribute.html

Next, review the installed package for an overview of API capabilities along with the Testbed sample application, which demonstrates coding examples. The package also provides users with the opportunity to retrieve data via the sample Excel files.

In addition, the API release notes, organized by built and date, further enhance the learning experience and render valuable syntax reference.


The next step is to get started with the GitHub guide and learn how to connect to the Trader Workstation, request market data, and place order types. Once your application is built, ensure you first test it in a simulated account with historical market data. After successfully testing, algo traders need to subscribe to real-time market data as outlined on our website.

In addition, be sure to monitor your account data and performance via the API. See GitHub for reference on syntax specifics.

Additional Resources

If you are interested in learning more about our API, our Traders’ Academy, Short Videos and Webinars provide a plethora of educational resources in engaging visual presentations, and supplemented with coding examples.
