What is max pain?

Why price drifts toward it

Max pain is really a description of where open interest is heaviest. As expiration nears, the gamma of near-the-money options grows, so dealer hedging around those crowded strikes becomes more forceful and more mean-reverting. The net effect of all that hedging is a pull toward the strike where the most contracts cluster — which is, by construction, close to max pain.

It is a tendency, not a law. Max pain works best on quiet, positive-gamma expirations; a strong trend or a fresh catalyst can easily override it.

What it is not

Max pain is not evidence that the market is 'manipulated' to hurt retail. It is an emergent result of hedging around concentrated open interest, and it moves as positioning changes right up to the close. Treating it as a fixed target set in advance misreads what it is.

It is also strictly an expiry-anchored idea: it is most meaningful in the final day or two before a major expiration and much weaker far from it.

How traders use it

Traders use max pain as a soft magnet on expiration days — a reference the tape often gravitates toward absent a strong catalyst. It pairs naturally with the call and put walls, which frame the range the pull toward max pain plays out inside.
