Plugins & Extras

Cracktrader keeps the core library focused on exchange connectivity, stores, feeds, and brokers. Optional indicators, analyzers, strategies, and runnable examples now live in the unified companion package named cracktrader_extras.

Installing extras

Extras are published as a separate wheel. Install it alongside the core package when you need the additional components:

pip install cracktrader_extras

The extras project registers entry points so Cracktrader can discover optional features at runtime. Use cracktrader.load(group) to fetch all plugins for a specific group:

import cracktrader

indicators = cracktrader.load("cracktrader.plugins.indicators")
print(indicators.keys())

If no extras are installed load() returns an empty dictionary, allowing you to write fallback logic easily.

Available entry point groups

The core library reserves three plugin namespaces:

• cracktrader.plugins.indicators
• cracktrader.plugins.analyzers
• cracktrader.plugins.strategies

Custom projects can contribute to these groups to register new functionality without modifying core code. Each entry point should resolve to an object (for example an indicator class) that Cracktrader can instantiate or expose.

Working inside the extras repo

cracktrader_extras packages community indicators and example strategies. It also doubles as an integration test suite because the runnable examples are executed as smoke tests in CI. Refer to that repository for contribution guidelines and additional documentation.
