Manifoldbt Backtester

manifoldbt-backtester

Runs a declarative strategy spec over OHLCV bars with the manifoldbt Rust engine, pairs the fill log into round trips, and emits the eight inputs the backtest-expert skill scores. Use when the user wants to execute a backtest, measure a rule they have described, obtain win rate / average win / average loss / max drawdown from real bars, or feed backtest-expert with measured numbers instead of estimates.

Install

Research and analysis tools, not financial advice. Some workflows use optional FMP, FINVIZ Elite or Alpaca accounts; the repo's five-skill starter path needs no API key. Open the repository

Run this in your project folder. It works with Claude Code, Cursor, Codex and dozens of other agents.

$ npx skills add tradermonty/claude-trading-skills --skill manifoldbt-backtester

Needs Node.js. Add -g to install for every project, or -a claude-code to skip the agent picker.

How to use Manifoldbt Backtester

Once it's installed, Claude reads this skill on its own whenever a request matches what it's for, so you don't have to mention it by name. In Claude Code you can also run it directly by typing /manifoldbt-backtester.

It includes scripts that Claude may run on your computer, so skim them on GitHub before you install.
