What it is

NautilusTrader is a production-grade, Rust-native event-driven trading engine with deterministic architecture, designed for algorithmic and quantitative trading. It combines Rust performance with Python bindings (via PyO3) to enable high-frequency strategy development, live trading, and backtesting across 20+ exchanges (Binance, Kraken, Coinbase, Bybit, OKX, Deribit, and more) with sub-microsecond latency. Cargo workspace monorepo under crates/ with specialized member crates: crates/core is the deterministic event engine, crates/adapters/ contains 20+ exchange integrations, crates/execution/, crates/portfolio/, and crates/risk/ implement trading logic, and crates/pyo3/…

Start here

Read these in order:

• crates/adapters/betfair/tests/common/mod.rs — Foundation: doesn't import anything internally and is imported by 5 other files. Read first to learn the vocabulary.
• crates/adapters/architect_ax/tests/common/mod.rs — Foundation: imported by 4, no internal dependencies of its own.
• crates/adapters/binance/src/spot/sbe/generated/mod.rs — Built on the foundation; imported by 1 downstream file.
• crates/adapters/binance/src/common/mod.rs — Built on the foundation; imported by 1 downstream file.
• crates/adapters/architect_ax/src/websocket/mod.rs — Layer 2 — application-level code that wires the lower layers together.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

1. Clone: git clone https://github.com/nautechsystems/nautilus_trader.git && cd nautilus_trader
2. Verify Rust version: rustc --version (requires 1.98.0+)
3. Build workspace: cargo build --release (or make build if Make targets exist)
4. Run tests: cargo test --all (test presence inferred from mature codebase)
5. Verify pyO3 bindings: python -m pip install -e . if Python bindings are packaged For complete setup, consult the Makefile and CONTRIBUTING.md in the repository root.

Daily commands:

Inferred commands from Cargo workspace:

1. Build core: cargo build -p nautilus-core --release
2. Build all: cargo build --workspace --release
3. Run tests: cargo test --all
4. Run specific crate tests: cargo test -p nautilus-trading
5. Run benchmarks: cargo bench -p nautilus-core (or check crates/adapters/architect_ax/benches/)
6. CLI: cargo run -p nautilus-cli -- <args> (or compiled binary) For Makefile targets, see the root Makefile in the repository (evidence present in file list but content not shown).

Key cautions & unknowns

• Single-maintainer risk — top contributor 94% of recent commits
• LGPL-3.0 is copyleft — check downstream compatibility
• 1. Rust edition 2024 requirement: rustc must be 1.98.0+; older versions will fail silently during cargo build. Verify with rustc --version before troubleshooting compilation errors. 2. **Workspace lockstep…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
