Crate nautilus_live 

Live system node for NautilusTrader.

The nautilus-live crate provides high-level abstractions and infrastructure for running live trading systems, including data streaming, execution management, and system lifecycle handling. It builds on top of the system kernel to provide simplified interfaces for live deployment:

• LiveNode High-level abstraction for live system nodes.
• LiveNodeConfig Configuration for live node deployment.
• AsyncRunner for managing system real-time data flow.

NautilusTrader

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, providing research-to-live semantic parity.

Feature Flags

This crate provides feature flags to control source code inclusion during compilation, depending on the intended use case, i.e. whether to provide Python bindings for the nautilus_trader Python package, or as part of a Rust only build.

• ffi: Enables the C foreign function interface (FFI) from cbindgen.
• streaming: Enables persistence dependency for streaming configuration.
• python: Enables Python bindings from PyO3 (auto-enables streaming).
• defi: Enables DeFi (Decentralized Finance) support.
• extension-module: Builds the crate as a Python extension module.
