Ranking factors, exclusions, and missing-data handling
- Ranking: contracts are ordered by annualized screen yield, descending. Ties broken by liquidity score.
- Minimum liquidity: strikes with open interest below 1 or absent bid/ask are excluded from the table.
- Pricing input: mid-of-bid-ask, falling back to last trade then day close when bid/ask are stale (after-hours / illiquid strikes).
- Excluded contracts: ITM strikes (we screen OTM only by default), spreads wider than 30% of mid, and strikes outside the 0.10–0.45 delta band.
- Missing-data handling: when Polygon returns no delta for a leg, we fall back to a Black-Scholes-Merton delta computed from spot, strike, DTE, and implied volatility. When IV is also missing, the strike is dropped.
- Why annualized screen yield is not a forecast: it assumes the same premium/strike combination repeats every cycle for a year, ignoring regime changes, IV crush, and post-assignment capital reallocation. Realized returns are typically materially lower. See annualized screen yield.
