How we rank credit spread structures
- Both legs liquidity-screened — bid-ask spreads checked before admission.
- Credit-to-width ratio computed as the primary capital-efficiency metric.
- Probability of expiring outside the short strike derived from current implied volatility.
- Distance from spot to short strike expressed in standard-deviation terms.
- Event windows (earnings, dividends, macro releases) flagged when inside the option's life.
- Composite rank balances credit-to-width, probability metrics, and event sensitivity.
What generic screeners miss
- Many screens rank by absolute credit and ignore the width that defines max loss.
- Probability metrics are often inconsistent across put-side and call-side candidates.
- Liquidity on the long leg is often ignored.
- Event-window risk is rarely a first-class ranking input.

Frequently asked questions
- What is a credit spread?
- A two-leg defined-risk position: short an option closer to the money and long an option farther out-of-the-money in the same expiration. Net credit is collected at entry.
- How is max loss controlled?
- By the spread width. The scanner reports max loss per candidate alongside credit collected and probability metrics.
- Are these signals?
- No. Output is a ranked list of analytically attractive structures. Execution decisions remain user-directed.
- Do you cover both bull put and bear call spreads?
- Yes. Both put-side and call-side credit structures are scanned and ranked on the same metrics.
- Why is this Pro-only?
- Multi-leg evaluation requires liquidity checks on both legs, probability modeling, and cross-strategy context that differs from single-leg ranking.
