A dealer takes the other side
When a trader buys a call, a market maker typically sells it — and is left holding directional (delta) risk it needs to neutralise.

What is gamma exposure (GEX)?
Gamma Exposure — GEX — measures the aggregate gamma held by options market makers (dealers) across all listed options on an underlying. It shows where dealer hedging is likely to create mechanical buying and selling pressure. It does not tell you which way price will go — it shows you where the friction is. It is market context, not a trade signal.

The mechanics
Why gamma exposure matters for price.
GEX comes from one simple chain: dealers hedge, and their hedging leaves a footprint. Follow it in three steps.
02
Delta changes as price moves
Gamma is the rate at which that delta shifts. As the underlying moves, the hedge drifts out of balance, so the dealer keeps rebalancing — buying as price rises, selling as it falls.
03
Re-hedging leaves a footprint
This is ongoing, mechanical and large-scale. At strikes with heavy open interest it concentrates into structural pressure zones. GEX makes those zones visible.
Positive vs negative gamma
The regime line: calm above, chaos below.
The single most-watched use of GEX is which side of the Gamma Flip price is on, because it changes how dealer hedging behaves.
Positive gamma · above the flip
Hedging dampens moves
Dealers buy the dips and sell the rallies — their hedging leans against price. Volatility tends to compress and ranges stay tighter. This is the calmer regime.
Negative gamma · below the flip
Hedging amplifies moves
Dealers must buy strength and sell weakness — their hedging leans with price. Moves can extend, and intraday range tends to expand. This is the more volatile regime.
The boundary between the two is the Gamma Flip. It marks a change in market character — it is structural context, never a trade signal.
The six levels
The six GEX levels, explained.
Each level is structural context derived from options open interest — never a guarantee and never a signal.
01
Call Wall
The strike with the highest concentration of call open interest. Dealer hedging there can create a structural resistance ceiling — context, not a hard stop.
02
Put Wall
The strike with the highest concentration of put open interest. Dealer hedging there can create structural support — context, not a guarantee.
03
Gamma Flip
Where aggregate dealer gamma crosses from positive to negative. Above it, hedging tends to dampen volatility; below it, hedging can amplify moves. A structural marker, not a trigger.
04
Focus Levels
Secondary zones of options concentration between the major Walls — notable clusters of activity worth watching.
05
Clusters
Areas where multiple strike-level hedging pressures overlap, indicating zones of compounded mechanical activity.
06
Battle Zones
Areas where call-side and put-side hedging are roughly balanced. Neither side dominates, so price can be choppy or indecisive.
GEX vs conventional TA
A different data source, used as context.
Conventional TA reads price and volume history. GEX reads options open interest and dealer positioning.
GEX often explains why a level matters — via hedging mechanics — rather than only that it exists.
GEX is context only. It is never treated as a buy/sell signal here.
Dealer-positioning context started on institutional desks and is now sold by several retail vendors; GEX Levels draws it inside TradingView without using an indicator slot.
GEX is not a crystal ball. It does not tell you whether price will reach a level, whether a level will hold or break, or when to enter or exit. It is most useful as one layer among several — combined with price action, orderflow, regime awareness and sound risk management. Two GEX-derived reads sit on top of these levels: the GEX Fear Score, which ranks how stressed a session is against twelve years of history, and Structural Agreement, which reads whether the day's structural forces line up or fight each other. Both are context, not signals. To go deeper, see how to read dealer positioning, or read the levels ticker by ticker — SPY, QQQ, NVDA, TSLA and more.

FAQ
Common questions about GEX.
What is Gamma Exposure (GEX)?
Gamma Exposure (GEX) measures the aggregate gamma position of market makers (dealers) across listed options for an underlying. It maps where dealer hedging is likely to create buying or selling pressure on price as the underlying moves.
What is the Gamma Flip?
The Gamma Flip is the price where aggregate dealer gamma switches from positive (net long gamma) to negative (net short gamma). Below it, dealer hedging can amplify moves; above it, hedging tends to dampen volatility.
Is GEX a buy or sell signal?
No. GEX is contextual information about market structure — where dealer hedging creates pressure zones. It is not a trade signal and is not a prediction of future price direction. Trading always involves risk of loss.
How do I use GEX levels on TradingView?
GEX Levels plots six GEX-based levels on your chart: Call Wall, Put Wall, Gamma Flip, Focus Levels, Clusters and Battle Zones. A 7-day free trial is available at /checkout/indicator-monthly — $9.99/mo after.
Is this the same as "Max Pain"?
Related but different. Max Pain is the expiry price where option holders lose the most. GEX levels are based on dealer gamma positioning and hedging flows, not expiry pinning. They sometimes converge but are separate calculations.
What is a Call Wall in GEX?
A Call Wall is the strike with the highest concentration of call open interest. Dealers who sold those calls must hedge by selling the underlying as price rises toward that strike — creating a structural resistance zone. It is a context marker derived from open interest, not a guaranteed reversal level.
What is a Put Wall in GEX?
A Put Wall is the strike with the highest concentration of put open interest. Dealers who sold those puts hedge by buying the underlying as price falls toward the strike — creating a structural support zone. Like all GEX levels, it is market context, not a trade signal or guaranteed floor.
What is positive vs. negative dealer gamma?
When aggregate dealer gamma is positive (above the Gamma Flip), dealers buy on dips and sell on rallies — their hedging dampens volatility. When dealer gamma is negative (below the Gamma Flip), dealers must buy as price rises and sell as it falls — their hedging can amplify moves and increase intraday range. This regime distinction is one of the most-watched uses of GEX data.
How is GEX different from traditional support and resistance?
Traditional S/R levels are drawn from past price action — areas where price previously turned. GEX levels come from current options open interest and dealer positioning. They explain mechanically why a level may matter (because dealers are forced to hedge there), rather than only that price reacted there before. They are complementary data sources, not substitutes for each other.
Is GEX Levels cheaper than SpotGamma?
Yes, on published prices as of July 2, 2026: our overlay is $9.99/mo (or $99.99/yr, about $77-84/yr), while SpotGamma's Standard tier is $89/mo (roughly $1,068/yr paid monthly, or $801/yr annual) and its Alpha tier is $299/mo. They are different products - SpotGamma is a full research dashboard; ours is a chart overlay - so "cheaper" only compares meaningfully if the chart overlay covers what you actually use. See our honest SpotGamma comparison for the full breakdown.
How does GEX Levels compare to MenthorQ?
MenthorQ Premium is $129/mo and Pro is $349/mo on their published pricing page (July 2, 2026 check) - roughly $1,548-$4,188 per year for a research platform with many models across asset classes. Our overlay is $9.99/mo for six gamma-derived levels on TradingView. If you use MenthorQ's model breadth every day, pay for it; if what you actually open is the call wall and gamma flip on an index chart, an overlay is engineered for that surface area. Full write-up: MenthorQ alternatives.
Do I need Unusual Whales for GEX levels?
Not for GEX levels specifically. Unusual Whales (~$48-75/mo at July 2, 2026 pricing) is a broad options-flow and market-data platform - flow, dark pools, congressional trades, screeners. If you use that breadth every session, pay for it. If your workflow is TradingView-first and what you want is a small number of gamma levels drawn on your chart, a $9.99/mo overlay does that specific job and only that job. See Unusual Whales alternatives for the full picture.
What are 0DTE options and how do they affect GEX?
0DTE (zero days to expiry) options expire the same day they trade. Because their gamma is extremely high near the money, even small moves in the underlying force large hedging adjustments. High 0DTE open interest can shift GEX levels intraday and cause sharper, faster mechanical flows than longer-dated options. The GEX Levels Library covers 0DTE gamma dynamics in a dedicated module.
