Dave Barnhart separates max pain, a simple arithmetic calculation of worthless options, from pinning, the real phenomenon where dealers hedge gamma risk near heavily loaded strikes. Pinning happens when expiration nears, open interest concentrates at one strike, and price sits close to it. Traders should track open interest distribution, not the max pain number.

Expiration week. A stock is trading a few dollars above a round number. It drifts. Chops sideways. Fades every rally. And on Friday, it closes almost exactly on that number, the same one somebody on the internet flagged on Monday as the max pain level. That happens often enough that people notice. So, which is it? Is price genuinely being pulled toward a level, or are we all just very good at remembering the times it lined up? The honest answer is, something real is happening. It's much narrower than the popular version, and it isn't happening for the reason most people say. Start with the definition, because it's often stated loosely. Max pain is a calculation. You take every open contract on the chain, and for each possible closing price, you work out how much total value would expire worthless. The strike where the largest dollar amount of options dies is the max pain price. The name comes from the idea that this is the price causing maximum financial pain to option buyers as a group. That's it. It's arithmetic on the chain. Nothing about the calculation itself claims price will go there. Here's where it goes sideways. The popular claim is that market makers deliberately drive price to that level so the maximum number of options expire worthless and they keep the premium. That version isn't right, and it's worth being specific about why. It would require firms that compete against each other to coordinate. It would require them to take enormous directional risk in a stock, the exact thing their entire business model is built to avoid. It would be illegal and heavily surveilled. And it assumes they're net short every option on the chain, which frequently isn't the case. So no, there's no roomful of people pushing the stock to a number. But, and this matters, the observation that gave rise to that story isn't imaginary. Price really does get sticky around heavily loaded strikes, Near expiry, there's just a much better explanation for it. The real mechanism is pinning, and we've already built every piece of it. When a strike carries very heavy open interest, and dealers are net owners of those options, they're hedging leans against price—selling as it rises, buying as it falls. That's the dampened regime from video four. Now add expiry. Gamma gets more violent as expiration approaches. So those hedging adjustments get larger and more frequent in the final days and hours. The result is a mechanical tug-of-war that keeps pulling price back toward the strike— not because anyone wants it there. Because that's what neutral risk management produces when a huge amount of positioning sits at one price and time is running out. That's real. It's documented. And it explains the Friday closes people notice. But notice the difference between pinning and the max pain number, because they're not the same thing. Pinning is local. It happens at a specific strike with enormous positioning, and only when price is already close to it. The strike does the work. Max pain is chain-wide. It collapses thousands of strikes into a single summary figure, which can sit several dollars away from where price actually is, and away from any individual strike that matters. So, when the max pain number happens to land on the same strike that's genuinely heavy and genuinely near price, It looks predictive. When it doesn't, and often it doesn't, price ignores it completely. The pinning was never coming from the summary statistic. It was coming from the concentration. That's the core problem with using Max Pain on its own. Any single number summarizing an entire chain throws away the thing you actually needed, where the concentration sits relative to price right now. 2 stocks can show the identical Max Pain level, One has a mountain of contracts sitting $1 from the current price. The other has its positioning scattered thinly across 20 strikes, with nothing meaningful nearby. Same number, completely different behavior ahead. Looking at the distribution tells you which situation you're in. Looking at the summary doesn't. So when does any of this deserve your attention? Four conditions, and you want most of them together: near expiry. The final day or 2, when gamma is at its most extreme. Early in a cycle, there's simply not enough hedging urgency to pin anything. A heavily optioned name, one where the options activity is large relative to how much the stock normally trades. On a name with thin options interest, this whole discussion is irrelevant. Price already close to the level? Pinning holds price near where it already is. It doesn't drag price across several dollars to get there. That's the single most common misuse. And no major news. Any real catalyst overwhelms hedging pressure instantly, and it stops being a factor. When all 4 line up, stickiness around that strike is a reasonable expectation. When they don't, the number is noise. Which points to a better habit. Instead of asking where the max pain number is, ask where the heaviest positioning sits relative to price right now, and whether the regime is one that dampens, moves, or amplifies them. That's the same information Max Payne was reaching for, without throwing away the detail. And it works on any day of the cycle, not just expiry week. Max Payne isn't useless. It's just a heavily compressed version of something you can look at directly. To be fair to both sides here, pinning near expiry in heavily optioned names is a genuine, observable effect. Dismissing the whole idea as superstition goes too far. But the broad claim that price reliably walks toward a chain-wide max pain figure over a week doesn't hold up. It works often enough to be memorable and fails often enough to be dangerous, which is the worst combination a signal can have. And it is never a reason to trade against a strong trend or to hold a losing position hoping price gets pulled back to a number. That's the most expensive way people use this. Real? But narrow. Treat it accordingly. So, to recap: max pain is a calculation, not a force. Nobody is pushing a stock to a number. What's actually happening is pinning— heavy positioning at a specific strike, plus expiry-week gamma, plus a regime where hedging leans against price. When those line up, price gets sticky. When they don't, the number is just a number. Watch the concentration, Not the summary, and never use it as a reason to fight a trend. MobyTick shows the actual distribution of positioning across the chain alongside the max pain level, so you can see whether the number is sitting on real concentration or on nothing at all. Next in the series, and it's the one I've been building toward. What happens when a large institutional print in the stock lands on the same price as heavy options positioning, and And why that combination is worth more than either signal alone.
