What is max pain?

Max pain (or "maximum pain") is the strike price at which the greatest number of option buyers would lose money if IWM settled there at expiration. For each candidate settlement price, sum the intrinsic value of every in-the-money call and put weighted by open interest; the price that minimizes that total payout is the max pain point.

Some traders watch max pain because of the theory that prices tend to gravitate toward this level as expiration approaches ("pinning"). The academic evidence is mixed — treat it as a read on positioning, not a prediction. The call wall and put wall (largest single-strike open interest) are often watched as near-term resistance and support zones for the same reason. Full walkthrough with a worked example: what is max pain?
