FixGateway - A FIX Engine supporting FIX versions 4.0, 4.1, 4.2, 4.3 (including FIXML). The package includes a C++ and Active X API. C# and JAVA APIs are available separately, as is an SSL integration kit allowing the FIX Engine to run sessions over Secure Sockets. FixGateway is very easy to configure and use, and represents particularly good value, when compared to other Fix Engines on the market. The demo download includes fully working code samples. FixGateway runs on all versions of Windows and x86 Linux.
