PutFinder

PutFinder is a live, rules-based cash-secured-put (CSP) screening engine at putfinder.com. Each trading day it scans the full option chain across a curated universe of liquid US names, scores every setup on a premium-vs-risk basis from documented indicators (IV30, volatility risk premium, Black–Scholes delta, downside buffer, an earnings gate), and records a timestamped snapshot of the rankings. The score is a descriptive relative ranking — it says a setup sits high in today's pool, not that it's a good trade or a predicted return. Built in public: the full methodology is published (putfinder.com/methodology) before any performance claim, the daily snapshots are already accumulating a forward-test dataset, and a public validation record comes later, only once there's enough verified history — no date promised. A focused, free, CSP-specific research alternative to broader options screeners like Barchart's options screener or Market Chameleon — a research tool, not a signals service, not a Discord, and not investment advice.
