WORK IN PROGRESS
The FlatBuffers interface allows you to write your own client code without being reliant on a closed source client library. Roq Trading Solutions will provide open sourced client libraries for the most popular programming languages.
Gateways can optionally be configured to allow clients to connect over TCP/IP and communicate using a FlatBuffers based protocol. This interface is not considered low latency since it has to use the kernel to communicate.
Use the C++ interface, if your use case requires low latency!
