# Hedge Wall Source: SquawkFlow URL: https://squawkflow.com/glossary/hedge-wall Category: Options Positioning Published: 2026-08-25 Type: Definition > SpotGamma's name for the price level where dealer hedging changes character, how it differs from the zero-gamma flip, and what can honestly be said about a proprietary level. --- ## What a hedge wall is Hedge Wall is a term coined and published by SpotGamma. It names a price level at which the character of dealer hedging is expected to change: above it, hedging flow is described as leaning against price moves and damping volatility; below it, hedging is described as leaning with moves and adding to them. If that sounds close to the zero-gamma flip, it is close, but the two are not synonyms, and the difference is worth being precise about. ## How it differs from the zero-gamma flip The zero-gamma flip is a computed root. You build a curve of estimated net dealer gamma as a function of spot price, then solve for where that curve crosses zero. Two people using the same chain, the same volatility inputs and the same positioning convention will land on close to the same number, because the definition fully determines the calculation. A hedge wall is a level a vendor publishes. SpotGamma has not disclosed the full construction, and there is no public specification you could implement to reproduce their figure. It is generally understood to be strike-anchored, a specific strike carrying a large hedging requirement, rather than an interpolated price between strikes, which is why a hedge wall tends to sit on a round number while a flip lands on something like 7,637.72. The practical consequence: a flip is a claim about a model, and a hedge wall is a claim about a proprietary model. Both are estimates. Only one is checkable. ## Why the ambiguity is the honest answer There is a temptation, when writing about a competitor's indicator, to state a precise definition and move on. We are not going to do that, because we would be inventing it. What can be said with confidence is the shared premise underneath every level of this family, hedge wall, [zero-gamma flip](/glossary/zero-gamma), [vol trigger](/learn/vol-trigger-explained), gamma flip. All of them assume a positioning convention: that dealers are, in aggregate, long calls and short puts against customer flow. Open interest records that a contract exists. It never records which side a dealer holds. Every level of this kind (SpotGamma's, ours, anyone's) inherits that assumption, and no amount of computational precision removes it. So when two vendors publish different levels for the same day, the disagreement is usually not that one is wrong. It is that they made different assumptions about positioning, used different volatility inputs, or anchored to a strike rather than interpolating between them. ## How traders use it The typical use is as a regime boundary rather than a target. A trader watching a hedge wall is asking which side of it price is on, and whether it has just crossed, because the crossing is the event, the point at which the expected behaviour of the tape changes from mean-reverting to trending. That framing survives regardless of whose level you use. Where it breaks down is in the transition zone. When price sits within a few tenths of a percent of any of these levels, the quantity being estimated is near zero, different estimators of it disagree, and the regime call is genuinely unstable. That is not a failure of the indicator. It is the indicator correctly reporting that the market is balanced on an edge. ## What we publish SquawkFlow does not compute a hedge wall, because we cannot reproduce a construction that has not been published, and we are not going to ship an approximation under someone else's name. We do publish the [zero-gamma flip](/gex), the vol trigger, and the call and put walls, computed from the full SPX chain, each with the time the snapshot was captured and the settlement open interest behind it. We publish no hold rate beside them. We showed one until August 2026 and withdrew it: it was measured against a third-party definition of a wall, and it was dominated by distance, because a wall four percent away from spot "holds" mostly on the days price never reached it, and near-money walls hold considerably less often than a headline number suggests. Our [SquawkFlow and SpotGamma comparison](/vs/spotgamma) sets out the rest of what each product does and does not publish. --- ## Citation Source: SquawkFlow, https://squawkflow.com/glossary/hedge-wall Retrieved: 2026-09-11 00:31 ET Attribution: cite the page URL rather than a copied number.
