What it does
yvictor-polars_backtest_extension is a Claude Code plugin that brings blazingly fast portfolio backtesting vocabulary and helpers into conversations where you are already using Polars. It targets indie builders, side-project quants, and small teams who validate allocation or signal ideas on historical data before they harden execution, infra, or a paid product. Install it when you want the agent to reason about backtest structure, Polars expressions, and portfolio metrics in the same thread as your data prep—not when you need a hosted broker or live trading stack. The plugin is a thin development extension rather than a full research platform, so pairing it with your own data files and risk rules stays your responsibility. On Skillselion it sits in Validate → Prototype because backtesting is the proof step between a hypothesis and a build commitment, even though you may reuse the same patterns during Build data pipelines.
Highlights
- Polars-native portfolio backtesting tuned for speed on large bar or position histories
- Expression and helper utilities that fit into existing Polars ETL and research notebooks
- Single focused plugin in the Yvictor repo—one install path for backtest workflows
- Useful when you already chose Polars and need agent help wiring backtest logic, not a separate GUI platform
- Community catalog entry with backtest, expressions, and helper keywords for discovery
Why builders use it
You have a strategy idea in Polars but spinning up a slow or fragmented backtest toolchain kills iteration before you know if the edge is real.
After you add the plugin, Claude Code can guide Polars backtest setup and expression patterns so you get quicker historical validation loops on your own data.
