Algorithmic and High-Frequency Trading API

roq-api

API for algorithmic and high-frequency trading (HFT).

Note! This project does not contain the implementation of the C++ interfaces. This is due to the ultra low latency communication protocol being closed source.

Features

• Open source interface (no need to sign an NDA to access or use).
• Permissive license (anyone is free to copy and use for whatever purpose).
• Unified interface for all markets.
• Design is strongly inspired by standards and specific implementations used by major exchanges.
• Allocation-free message decoding.
• Auto-generated code based on schemas.
• Strongly typed messages (events).
• Asynchronous interfaces and implementations.
• C++ for ultra low latency.
• FlatBuffers as an optional interface when latency is not a concern.

Operating Systems

• Linux (x86-64, AArch64)
• macOS (x86-64)

Library/Package Dependencies

• FlatBuffers (Apache 2.0 License)
• fmt (MIT License)
• range-v3 (BSL 1.0 License)
