IB-API-Software
Use our proprietary programming interface (API) and create your own automated, rule-based trading software using your preferred programming language/protocol, such as:
Java - Our most popular API technology
C++ (POSIX compliant)
Python
.NET (C#) - you can use C# library with any language supported by .NET
C++ (MFC)
ActiveX - Integrate our ActiveX control with other programs, such as Excel and Matlab
DDE - Use our Excel sample application or any other DDE sensitive program as a starting point.
Test your system
Our API requires a connection via Trader Workstation (TWS) or IB Gateway. Always test your API components via your Paper Trading account or using the TWS demo system before effectively implementing a new API system.
Solutions for everyone Trader types
Notes:
¹ The C++ (MFC) API is obsolete as of API version 9.72.
