Max pain shows up on every options screener with a confident single number, implying the market is fated to land there by expiration. It's a real, calculable concept — and it's also one of the most overstated tools in retail options trading. Here's what it actually measures, and where it fits next to the gamma levels that do a better job explaining price behavior.
What max pain is
Max pain is the strike price at which the largest number of options — calls and puts combined, by dollar value — expire worthless, meaning option buyers lose the most money and option sellers (largely market makers and institutions) lose the least. It's calculated by running through every strike, totaling the intrinsic value all open calls and puts would be worth if the stock settled there, and finding the strike that minimizes the total payout to option holders.
The theory behind it
The max pain theory argues that because market makers are net short most of the open interest (they sold the options to the public), they have a financial incentive — and, the theory claims, enough size to actually do it — to pin the stock near the max pain strike into expiration, minimizing what they have to pay out. It's an appealing story: a single number that supposedly reveals where "they" want price to land.
Does it actually work?
Mixed, and less than the hype suggests. Max pain is a static, backward-looking calculation — it treats every open contract as equally likely to matter and ignores how dealers are actually positioned right now, including the delta and gamma hedging flows that dominate the real mechanics of price movement into expiration (see Delta Hedging Explained). It also assumes market makers are both willing and able to coordinate price toward a single strike, which oversimplifies a market with many participants beyond option sellers. Max pain has some pull on quiet, low-volume expirations with little else driving price — but on an active session with real catalysts or heavy directional flow, it's routinely overridden.
Max pain vs. gamma walls
This is the more useful comparison. The call wall and put wall are also concentrations of options positioning, but they're derived from gamma exposure — the actual hedging flows dealers are mechanically forced into as price moves — rather than a static "who loses the most" calculation. Gamma walls explain why price gets sticky at a level (dealers are buying or selling the underlying to stay hedged, in real time). Max pain only explains where the payout math nets out lowest, with no mechanism forcing price there. When max pain and a gamma wall land near the same strike, that's a stronger combined case for a pin — and a reason to manage pin risk on any short options near that strike. When they diverge, the gamma read is generally the more mechanically grounded one — see What Is GEX? for the fuller picture of that hedging force.
Where max pain still adds value
Use it as a secondary reference, not a primary signal. On expiration day specifically, especially with low realized volatility and no scheduled catalysts, max pain can be a reasonable tiebreaker for where a range-bound session settles — useful context for sizing an iron condor's strikes or deciding whether to hold a position into the close. A butterfly spread, which needs price to land at one specific strike rather than a range, leans on max pain even more directly as a candidate for where to center the body. It's also worth checking relative to the gamma flip: if max pain sits on the same side of the flip as current price, that's mild confirmation; if it sits on the opposite side, the gamma regime is the read to trust.
Reading it correctly
Don't trade off max pain alone, and don't treat it as a prediction — treat it as one more data point in a stack that includes the gamma walls, the flip level, and actual options flow. If you're short options near the max pain strike heading into expiration, manage pin risk accordingly. Thermal shows max pain directly alongside the call wall, put wall, and gamma flip on the same profile, so you can see at a glance whether they agree or disagree instead of chasing max pain as a standalone number.
