Methodology (How the scanner works)

This page explains what we mean by Probability of Profit (PoP), the assumptions behind it, and what we intentionally filter out.
Educational only — not financial advice.

What “PoP” means here

PoP is an estimate of the chance a spread expires at max profit (or within a profit zone), based on option prices and volatility. It is a model-based estimate — not a guarantee.

Uses market-implied inputs (like IV) + standard option math assumptions.
Assumes liquid markets and normal execution constraints (fills, slippage).
Does not know future news, gaps, or regime shifts.

Assumptions (and why they matter)

Volatility is not constant: models can be wrong when IV changes fast.
Early management changes outcomes: exiting early can raise win rate and lower tail risk.
Execution matters: wide bid/ask spreads and low liquidity can wreck theoretical edges.

What we filter out (by design)

Illiquid chains (poor fills, misleading prices)
Spreads with unattractive risk/reward for the given PoP
Setups that fail basic sanity checks (pricing/greeks inconsistencies)
