Max pain is the strike at which the largest dollar value of options expires worthless — the theoretical point of maximum loss for option buyers (and maximum gain for sellers). It’s widely cited and widely overstated.
The theory
The idea: since option sellers (often market makers) profit when options expire worthless, and their hedging influences price, the market may gravitate toward the strike that causes the most options to expire worthless — “max pain” for buyers. It’s computed from open interest across strikes as the price where total option value is minimized.
The real limits
Max pain is a rough gravitational idea, not a precise magnet. It correlates loosely with pinning because both stem from dealer positioning, but it’s often conflated with the more rigorous gamma-based pinning story. Price frequently closes away from max pain, especially on trending or catalyst days. Treat it as a weak, loose reference — not a prediction.
Max pain is a folk version of the pin: a loose gravitational strike, not a law. The gamma and charm story explains pinning better — and price ignores max pain plenty.
What it means for a scalper
Don’t trade off max pain as a signal — it’s a rough context number at best. The more actionable version is the actual heavy strikes and gamma-driven pin, which NoVo maps live. Max pain is worth knowing as a term you’ll hear, mostly so you can weight it correctly (lightly).
