About
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 developers, 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.
- 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

What it does
Run fast portfolio backtests on Polars DataFrames without leaving Claude Code while you validate trading or allocation ideas.
Who is it for?
Best when you're already on Polars and want agent-assisted backtest scaffolding while prototyping trading, robo-advisory, or portfolio analytics features.
Skip if: Skip if you need regulated production execution, licensed market data feeds, or a no-code backtest SaaS without writing Polars pipelines.
What you get
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.
- Agent-guided Polars backtest structure and helper usage aligned to your notebook or script
- Faster iterate-and-compare loops on portfolio rules before production build
- Clearer mapping from validation hypotheses to Polars pipeline code
