Pair Trade Screener

**Quick judgment** Well-designed, statistically grounded tool for pair-trade screening and analysis. It offers a full pipeline from universe definition to actionable entry/exit suggestions, suitable for users who understand quantitative trading concepts and can supply an FMP API key. **Key strengths** - Robust methodology: correlation + cointegration + z-score + half-life, with clear quality criteria. - Practical trading rules: conservative/aggressive thresholds, stop-loss logic, and market-neutral sizing. - Strong documentation with concrete workflows, CLI options, and output formats. **Main risks / limitations** - Financial risk: Outputs can be mistaken for personalized investment advice; real-world performance depends on execution quality, regime shifts, and transaction costs. - Data dependency: Relies on FMP API (availability, rate limits, and correctness), plus correct API-key configuration. - Model/structural risk: Cointegration relationships can break after corporate events or regime changes; the skill outlines red flags, but users must still apply judgment. **Recommended scenarios** - Quantitative or semi-quantitative users seeking market-neutral, mean-reversion opportunities within liquid equity universes. - Traders or researchers who want a systematic way to generate and rank pair-trading candidates before more detailed backtesting. - Portfolio builders who need a repeatable process to maintain a small book of diversified pair trades alongside other strategies.
