GEX Glossary: Gamma Exposure Terms, Explained

Every core term behind gamma exposure and GEX levels, defined in plain language. Each entry links to a deeper guide, so you can move from a one-line definition to the full mechanism whenever a term matters. Educational reference only — nothing here is a signal.

INDICATOR REFERENCE · CHROME 4.6.5

Every setting. Every chart abbreviation.

107 controls from the current Options page, 10 profiles, keyboard shortcuts and chart terms. Native builds may expose a subset or different names. These are descriptions, not trading signals.

Chart abbreviations and data states

GEX / γ — Gamma exposure

Aggregate option gamma exposure under the selected model and basis. Read the source's units: raw gamma, dollar exposure and exposure per 1% move are not interchangeable. It is an estimate of positioning, not observed dealer inventory.

DEX / Δ — Delta exposure

Aggregate directional delta exposure. The displayed per-strike total is distinct from an individual option's delta and from the price level itself.

CW / PW — Call / Put Wall

Selected call-side and put-side gamma concentrations. A wall can already be crossed; the name does not guarantee that it is above/below current spot or that price will reverse.

GF — Gamma Flip

The served/provider gamma-regime boundary, or the model crossing when selected in Gamma Flip line source. Check that setting before comparing values.

ZG / Zero Gamma — Model crossing

The application's re-priced net-gamma zero crossing. May differ from provider GF and VT because definitions and inputs differ.

VT — Vol Trigger

Provider zero-gamma/volatility-trigger reference when supplied. Availability and meaning follow the selected source; it is not an order trigger.

F1 / F2 / F3 / POI — Focus levels

Ranked reference strikes according to the account's scoring profile. Balanced may combine several exposures; custom or single-factor profiles need not have broad confluence.

MP — Max Pain

Strike minimizing modelled aggregate intrinsic option payout at expiry given open interest. Not a forecast or guaranteed price magnet.

OI / Call OI / Put OI

Open interest is outstanding option contracts. OI walls identify concentrations without gamma weighting. Settlement OI is not the same as intraday traded volume.

0DEX — Zero delta exposure

A zero crossing in the served delta-exposure construction. Distinct from a gamma sign change.

CW·H / PW·H — Hybrid walls

Alternative walls using the served positioning construction. Agreement is descriptive, not a validated increase in win probability.

Vanna / VF / Vanna 1–4

Vanna measures sensitivity of delta to implied volatility. VF is the vanna sign-change reference; numbered walls locate concentrations where provided.

Charm / CF / Charm 1–3

Charm measures change in delta with time under the model's convention. CF is the charm sign-change reference; numbered levels mark concentrations.

Vega / Vega 1–4

Vega measures option-price sensitivity to implied volatility. Numbered levels mark served concentrations, not gamma walls.

CW+1… / PW-1… — Wall extenders

Strong gamma strikes beyond the main walls, selected from the available profile. They extend the map without moving its primary anchors.

BZ / UCL / DCL

Battle Zone and upside/downside clusters are bands grouping nearby structural strikes. They are zones, not exact guaranteed reversal prices.

EM / ±1σ — Expected move

Model-implied range for a specified horizon. Statistical assumptions, volatility changes and tails mean it is not a guaranteed containment range.

IV / ATM IV / IV zone

Implied volatility; ATM means at the money. IV-based zones depend on the selected horizon and available inputs.

IV-C / IV-P — IV walls

Experimental call/put references using OI weighted by IV excess over the side median. Not validated support/resistance or gamma walls.

VWAP / σ bands

Volume-weighted average price and dispersion bands for the served session. Futures-only references use the available futures reference data, not the ETF option chain.

ONH / ONL / ON inventory

Overnight high/low and inventory context. Session boundaries and futures availability matter; not native ETF-derived option levels.

PDH / PDL / RTH / RTH open

Prior-day high/low, regular trading hours, and that session's opening price. They describe a trading session, not an option expiry.

OR / ORH / ORL

Opening range and its high/low over the configured/served opening window. Do not assume every platform uses the same window.

ICT / Asia / London / NY-AM / Midnight open

Time-window/session reference overlays. Times follow their configured market timezone, not necessarily your computer clock.

[NDX] / QQQ / SPX / SPY

Index versus ETF option contexts. [NDX] identifies the index-derived layer; projected prices do not make the option inventories identical.

Converted levels

A converted level uses the selected instrument's price scale. Check the source and conversion ratio shown with the map.

M / B / Γ / Δ in axis labels

M = million (xxx.xxM); B = billion (x.xB). Γ identifies gamma exposure and Δ delta exposure when selected. These amounts are not prices or contract quantities unless explicitly labelled as such.

+ / − distance / EM distance

Signed distance between the displayed reference price and a level, in points or expected-move units as selected. Not a PnL projection.

VH / H / M / L

Focus confluence grades: very high, high, medium, low. They describe scoring/confluence, not success probability. M here means Medium, not millions.

DAG — Delta-adjusted gamma

A gamma-related scoring field adjusted by delta under its source model; distinct from plain GEX or DEX.

FLOW / OI / HYBRID / Estimated OI

Different data bases for the map: executed-flow context, settlement open interest, combined basis or intraday OI estimate. Coverage and update times differ.

Locked / Frozen / Stale / Unavailable

Locked is a confirmed current-session opening capture. Frozen is a user pause. Stale means data no longer meets the current freshness/session checks. Unavailable means required data is missing. Paused polling alone must not turn a valid lock stale.

Timing / proxy / converted

Timing identifies the reference timestamp; proxy/converted describes projection from another underlying. Neither term implies native futures-option positioning.

GEX heatmap / Charm map / Greek heatmap

Per-strike exposure shading. Color/sign describes exposure, not a buy/sell instruction; opacity and strength filtering do not alter the source values.

Ab1 / Ab2 / Ab3 / DEX extremes

Absolute gamma peaks ignore gamma sign; DEX extremes locate large directional exposures. Experimental additional constructions remain separate from Focus scoring.

A1–A14 / B2–B5

Internal family identifiers shown in the advanced settings labels. Each available family is documented by its exact code and control in All settings below; not a probability grade.

Flow / sweep / net drift

Executed option activity, sweep-style prints and net directional flow summaries where supplied. They describe reported transactions, not proven institutional intent or future price direction.

Fear / percentile / VIX / VVIX

Volatility/context readouts. A percentile is a rank in its reference sample; VIX and VVIX measure different implied-volatility quantities. None is a calibrated trade success probability.

P/C / COT / net liquidity

Put/call ratio, Commitments of Traders positioning and macro liquidity context. These have different units and publication cadences; not all are live intraday observations.

Strike / expiry / 0DTE / spot

Strike is an option exercise price, expiry its maturity, 0DTE expires that day, spot the reference underlying price. A chart's future contract and the option chain's underlying may differ.

Long γ / Short γ

Estimated positive/negative gamma regimes under the model. Hedging may dampen/amplify moves under assumptions, but flows and other participants can overwhelm that effect.

Two-book aggregate

SPY and SPX are separate option books on one underlying, so summing them is not double counting: it reconstitutes what an index-futures trader is actually hedged against. Draws only when the aggregate’s own price scale lands on the chart you are looking at, and shows which book each level came from.

Measured dealer sign (panel)

extended-flowDealer

The direction of classified aggressive flow and what it mechanically implies for the dealer. This is a derivative, not a reclassification of open interest, and it is not an equivalent of SpotGamma’s Synthetic OI. The flow-versus-open-interest ratio is printed beside it: a clear sign on 1,600 contracts facing 40,000 of open interest is 4 % of the stock, and the row says so. When the data source publishes only a net premium, no sign is shown at all rather than a guessed one.

Chrome → Options → Order flow
Order flow · Immediate

Session flow (panel)

extended-flowSession

Directional pressure over the whole window, the put/call premium ratio, and the share of the tape the source actually managed to classify. That last number qualifies every other flow reading here.

Net drift slope (panel)

extended-driftDerivative

Distance in expected-moves

showEmDistance

Alongside the point distance, show how far each level is in 1σ expected-moves, e.g. “· 0,42× EM” — so “close” vs “far” reads in the day’s own scale. Needs ATM IV; hidden when the point distance is off.

Remember layers per symbol

perSymbolLayers

Off by default — settings stay global. When on, switching symbol in the panel saves the layers you had on for the old symbol and restores the new symbol’s own set, so each ticker keeps the view you use for it.

Core GEX terms

GEX (Gamma Exposure)
How much option gamma dealers hold across strikes, expressed as the dollar change in aggregate dealer delta per one-point move in the underlying. GEX is the footprint that turns option positioning into levels on a chart. Read: What is GEX? →
Gamma Exposure
The full name for GEX. It captures where dealer hedging concentrates and whether that hedging will dampen or amplify moves. Read: Gamma exposure explained →
Gamma Flip
The served gamma-regime boundary. Check the selected source and the gamma sign on each side: positive gamma need not always lie above a crossing, and several crossings can exist. Hedging effects are model-dependent, not a guaranteed price response. Read: The gamma flip →
Zero Gamma
The underlying price where the model's re-priced net gamma crosses zero. This can differ from the provider Gamma Flip and Vol Trigger because the inputs and definitions differ. Read: The gamma flip →
GEX Profile
The shape of dealer gamma plotted across strikes. A sharply peaked profile means a strong centre of gravity and likely pinning; a flat profile means a market free to travel. Read: The GEX profile →

Levels & zones

Call Wall
A selected call-side gamma concentration. It may already be below current spot after being crossed. Its importance depends on exposure, nearby strikes and the gamma regime; it is not guaranteed resistance. Read: The call wall →
Put Wall
A selected put-side gamma concentration. It may already be above current spot after being crossed. Its importance depends on exposure, nearby strikes and the gamma regime; it is not guaranteed support. Read: The put wall →
Gamma Cluster
A tight band of adjacent strikes that together hold heavy gamma, behaving as one thick reaction zone rather than a single precise line. Trade its edges, not its interior. Read: Gamma levels →
Gamma Void
A region between levels with little dealer gamma, where hedging offers little resistance and price can move quickly across the gap. Read: The GEX profile →
Expected Move
The one-standard-deviation range the options market implies for a session or period. Used to judge whether a move is ordinary or has become statistically large. Read: The expected move →

Dealers & regime

Dealer Gamma
The gamma inventory held by options market makers. Their delta-hedging of that inventory is the mechanical force that makes GEX levels matter at all. Read: Dealer positioning →
Dealer Positioning
The overall shape of market-maker exposure across gamma, delta, vanna and charm — the thing that determines whether hedging dampens or amplifies the tape today. Read: Dealer positioning →
Positive Gamma
A regime where dealers are net long gamma, so their hedging leans against price. Moves tend to be dampened and mean-reverting. Read: Positive vs negative gamma →
Negative Gamma
A regime where dealers are net short gamma, so their hedging chases price. Moves tend to be amplified and can accelerate — the condition behind many sharp trends. Read: Positive vs negative gamma →
Options Flow
The stream of executed option orders — especially aggressive premium — that shows where participants are paying up relative to the standing structure. Flow tests the map; positioning draws it. Read: How to read options flow →

The Greeks behind GEX

Delta
The sensitivity of an option's price to a one-point move in the underlying — and the quantity dealers hedge to stay neutral. Gamma is how fast delta itself changes. Read: Delta explained →
Vanna
The sensitivity of delta to a change in implied volatility. Vanna links volatility shifts to directional dealer hedging — the fuel behind some of the sharpest moves on vol-shift days. Read: Vanna →
Charm
The sensitivity of delta to the passage of time. Charm drives mechanical hedge unwinding, especially into the afternoon and toward expiry — one ingredient of late-day drift. Read: Charm →
Vega
The sensitivity of an option's price to a change in implied volatility, marking where the dealer book is most exposed to volatility moves. Read: Vega →
Open Interest
The number of option contracts outstanding at a strike — a standing-inventory input that complements the flow-based view of positioning. Read: Open interest explained →
Vol Trigger
The price at which dealer gamma is judged to change sign in the data supplier’s own construction — broadly, where hedging stops damping moves and starts amplifying them. It is a supplied field rather than one we compute, so it is not always published: when the upstream member serving a session does not carry it, the level is absent rather than estimated. Our own Zero Gamma is the construction we publish in its place.
Battle Zone
A narrow band around the level where opposing option positioning is most closely matched, so neither side’s hedging clearly dominates. Price inside it tends to be choppier than the surrounding structure would suggest; it describes a condition, never a direction.
UCL (Upper Cluster Level)
The upper edge of the nearest cluster of gamma above spot — the first place above price where option exposure is dense enough to matter to hedging. See Gamma Cluster.
DCL (Downside Cluster Level)
The lower edge of the nearest cluster of gamma below spot, the mirror of UCL. Together the two bracket price with the structure that is actually near enough to trade against, rather than the largest strike anywhere on the board.
