Backtesting

NautilusTrader

High-performance algorithmic trading platform (Rust core, used from Python) that runs the same strategy code in backtests and live.

Our take

Professional-grade engine for people who want the same code in backtests and live trading.

Who it is for

Experienced programmers who want a serious, fast engine with the same code in backtests and live.

Very active project (over 30,000 GitHub stars, daily commits in October 2026).
Rust core with Python for strategy logic.
The same strategy code runs in backtests and live, which reduces surprises when going live.
Around 20 integrations, including Binance, Interactive Brokers, Betfair, Polymarket and Databento.

The README itself warns that live trading can differ from backtests because of venue, network and timing behavior.
Some integrations are marked "planned" or "building", not stable.
It is a professional tool: not for learning to code.
LGPL-3.0 license: if you distribute software that modifies it, you have license obligations.
