Overview

CQG Algo API is a high-level command and control API which can be used to build scripts or integrate CQG Algo Server into your existing ecosystem. The API is divided into several independent "services" responsible for different aspects of the system. A service can define both, remote procedure call (RPC) and incremental streaming data.

CQG Algo Server uses Google Protocol Buffers as an interface definition language similar to GRPC and it is backed by our custom high-performance TCP protocol. We support C#/.NET and C++ and the architecture is designed for an easy extension. Please, contact APIHelp to discuss your specific business needs.
