Examples

Python scripts are organized by system environment context:

• Backtest: Historical data with simulated venues.
• Live: LiveNode examples for live, sandbox, and testnet venues.
• Other: Various examples beyond strategies.

Scripts within each environment context directory are organized by integration.

Live adapter examples

Maintained Rust-native adapter testers use the generic data_tester.py and exec_tester.py names under live/<adapter>/. These replace the removed adapter-prefixed tester variants. The maintained sandbox execution tester is live/sandbox/exec_tester.py.

All tracked Python examples import the current public package surface. Adapter examples use nautilus_trader.live.LiveNode, built-in tester configs from nautilus_trader.testkit, or self-contained actors and strategies maintained with the example.

Ensure that the nautilus_trader package is either compiled from source or installed via pip before running the examples. See the installation guide for more information.

From the repository root, run a Rust-native adapter tester against the venue testnet:

.venv/bin/python examples/live/lighter/data_tester.py

The script connects immediately and streams market data; stop it with Ctrl+C.
