## Key facts

- NautilusTrader is developed by Nautech Systems Pty Ltd (ABN 88 609 589 237), founded in 2015 and
  self-funded with no outside investors.
- The open-source engine is licensed LGPL-3.0-or-later. Source is on
  [GitHub](https://github.com/nautechsystems/nautilus_trader); packages are published to
  [PyPI](https://pypi.org/project/nautilus-trader/) and [crates.io](https://crates.io/crates/nautilus-core).
- The open-source engine supports research, backtesting, simulation, and live trading workflows.
- The architecture uses an event-driven core, nanosecond timestamps, deterministic replay, and
  shared engine semantics between backtest and live environments.
- Python strategy code runs against performance-sensitive Rust components.
- 40,000+ automated unit, integration, acceptance, property-based, and simulation tests run across
  Python and Rust, with nightly Miri checks and deterministic simulation testing (DST).
- Wheels carry SLSA build provenance, Docker images are Cosign-signed with Sigstore-attested SPDX
  SBOMs, and PyPI and crates.io releases use Trusted Publishing (OIDC).
- NautilusTrader is trading software only. Nautech Systems is not a broker, dealer, exchange, or
  financial adviser.
