NautilusTrader is a production-grade, Rust-native trading engine with a deterministic, event-driven architecture, aimed at building trading systems across research, deterministic simulation, and live execution. It uses Python as a control plane for strategy logic, configuration, and orchestration, and provides modular adapters to integrate many REST and WebSocket-based venues. It is useful for algorithmic trading workflows including backtesting and live multi-venue trading.
