 Introduction

NautilusTrader is an open-source, production-grade, Rust-native engine for multi-asset,
multi-venue trading systems.

The system spans research, deterministic simulation, and live execution within a single
event-driven architecture, with Python serving as the control plane for strategy logic,
configuration, and orchestration.

This separation provides the performance and safety of a compiled trading engine with
the flexibility of Python for system composition and strategy development.
Trading systems can also be written entirely in Rust for mission-critical workloads.

The same strategy and execution-algorithm code can run across backtest and live systems, reducing
deployment divergence. Live execution still introduces venue, transport, timing, persistence,
external-activity, and reconciliation behavior that a simulation may not reproduce. See
Backtest and live differences.

NautilusTrader is asset-class-agnostic. Any venue with a REST API or WebSocket feed can be
integrated through modular adapters. Current integrations span crypto exchanges (CEX and
DEX), traditional markets (FX, equities, futures, options), and betting exchanges.
