Gamma Exposure Intelligence

See what dealers
are forced to do.

Options dealers hold positions that mechanically obligate them to buy or sell shares as price moves. Gamma Sonar maps those obligations — recomputed from live greeks every 60 seconds on SPX, SPY, QQQ and major indices — with 90+ additional tickers on 5-minute cycles. Not predictions. Not patterns. The structural reality of dealer positioning.

What is Gamma Exposure?

Every option trade has a dealer on the other side. To stay neutral, dealers must continuously buy or sell shares as price moves. How much they must trade is driven by gamma — and that creates two very different market environments.

Positive Gamma

Dealers hedge against the direction of price. Stock rises → they sell. Stock falls → they buy. Moves get dampened. Ranges tighten. Volatility compresses.

↓ Price drops → Dealers BUY → Price stabilizes

Negative Gamma

Dealers hedge with the direction of price. Stock rises → they buy more. Stock falls → they sell more. Moves accelerate. Ranges expand. Volatility spikes.

↓ Price drops → Dealers SELL → Price accelerates down

Gamma Sonar maps this exposure across every strike and every expiration. The result is a structural view that reveals where mechanical buying and selling pressure is estimated to concentrate — independent of opinions, fundamentals, or chart patterns.

16+ Live Analytical Tools

Every tool answers one question: what are dealers mechanically obligated to do — and where?

Pressure Field

Strike-by-strike GEX with 7-layer stack. Chart overlay. 0DTE through LEAPS expiry filtering.

Flow Tape

Server-side enriched flow. Sweep/block detection, OI exceedance, dealer side inference. $25K+ floor.

Regime Classifier

7-state model with hysteresis. Compression, Negative Gamma, Cascade Risk, Escape Velocity, Pinned, Trending.

SSSORIGINAL

15-feature regime transition detection. Trained on 120 days. WATCH → CAUTION → IMMINENT → CONFIRMED.

Term Structure

Strike × expiry heatmap. GEX, OI, delta, gamma, vanna clustering across the full surface.

Vanna / Charm

Per-expiry second-order greek exposure. Time decay and volatility forces driving dealer re-hedging.

IV Surface

Full implied volatility heatmap across strikes and expirations. Call and put IV.

Skew Dynamics

Live 25-delta, 10-delta, ATM skew. Intraday session history shows how tail risk pricing evolves.

Max Pain

Multi-expiry computation. Daily, weekly, monthly, quarterly. Intraday drift timeline.

RVX Spread

Realized vol vs. implied vol. Options priced rich or cheap relative to actual movement.

Pin Risk

Per-expiry OI + gamma concentration. Gaussian pin probability near key expiration strikes.

Cross-Asset

95-ticker simultaneous view. Spot, GEX, regime, ATM IV across every name at a glance.

5 Proprietary Signals

Built from years of watching how dealer mechanics actually move price. These metrics exist on no other platform.

SSS
Structural Stress Score

15-feature composite model monitoring structural stress indicators simultaneously. Outputs a 0-100 score. Trained on 3,096 snapshots across 120 trading days. Detects the conditions that have historically preceded regime transitions — the moments when forced dealer behavior creates the fastest moves.

NO COMPETITOR EQUIVALENT
FPI
Flow Pressure Index

Delta-weighted, proximity-scaled flow oscillator. Distills live options activity into a -1 to +1 directional reading — weighted by proximity to structural levels.

REGD
Regime Divergence

Measures the gap between actual price behavior and what the gamma structure implies. When the model and reality disagree, something outside the structure is driving price.

GVWAP
Gamma Volume-Weighted Avg Price

The center of gravity of the gamma positioning structure. Shows where most exposure is concentrated — a structural reversion reference level.

HV
Hedging Velocity

Compares actual hedging flow to theoretical requirements. Under-hedged dealers produce catch-up flow. Over-hedged conditions precede exhaustion.

Built on the Real Feed

OPRA Consolidated

All 18 US options exchanges. Same feed institutional desks use. Not sampled. Not delayed.

Live Greeks

Recomputed every 60 seconds on major indices, 5 minutes across 95 tickers. Not stale overnight snapshots most platforms rely on.

0DTE From Open

Same-day expiry gamma included from market open. The most important intraday structural factor.

Pre-Market

Frequently Asked

What is Gamma Exposure and why does it matter for day trading?
Gamma Exposure (GEX) measures how much buying or selling options dealers may need to do as price moves. Dealers must continuously hedge their positions to stay neutral. These hedging flows are mechanical — driven by math, not opinion — and they can meaningfully influence price. GEX maps where these flows are estimated to be strongest at each strike price, giving you a structural view of support and resistance that has nothing to do with chart patterns.
How often does Gamma Sonar update?
Index GEX — SPX, SPY, QQQ, and major indices — is recomputed from live greeks every 60 seconds during market hours (9:30 AM – 4:00 PM ET). All other tickers refresh on 5-minute cycles. Pre-market structural levels are available by 6:35 AM ET. The Flow Tape updates in real-time via WebSocket as trades arrive. All subscribers receive the same update frequency — there is no throttled or delayed feed.
What tickers does Gamma Sonar cover?
95 tickers spanning major indices (SPX, NDX, RUT, DJI), mega-cap tech (AAPL, MSFT, NVDA, AMZN, GOOGL, META, TSLA), high-beta names (COIN, MSTR, PLTR), sector ETFs (XLF, XLE, GLD, TLT), and high-activity options names. All expirations from 0DTE through LEAPS are included.
Where does the data come from?
Consolidated OPRA data from all 18 US options exchanges, delivered via ThetaData. Greeks are computed from live options data — not stale overnight snapshots. This is the same consolidated feed used by institutional trading desks.
Is this financial advice?
No. Gamma Sonar provides structural market analytics for educational purposes. Nothing on the platform constitutes investment advice, a trading signal, or a recommendation. We describe estimated mechanical dealer obligations — not predictions. All models involve assumptions that may not hold. You are solely responsible for your trading decisions.
What is the Structural Stress Score (SSS)?
A proprietary 15-feature composite metric monitoring structural stress indicators. It outputs a 0-100 score that rises as precursor conditions activate. Trained on 3,096 snapshots across 120 trading days. Higher readings have historically been associated with conditions preceding regime transitions. SSS is observational — it does not predict direction or guarantee outcomes.
What is the Founding Member offer?
All subscriptions start with a 7-day free trial — no charge until the trial ends. The next 100 subscribers get 30% off — forever, as long as the subscription is active. That is $174.30/mo instead of $249/mo. Use code FOUNDING100 at checkout. Once all 100 founding spots are claimed, the offer closes permanently.
How is this different from other GEX platforms?
Most platforms compute GEX from overnight snapshots with stale greeks. Gamma Sonar recomputes index GEX from live greeks every 60 seconds, with 90+ additional tickers on 5-minute cycles. Beyond update speed, we offer 5 original signals (SSS, FPI, REGD, GVWAP, Hedging Velocity) that exist on no other platform, a 7-state regime classifier with hysteresis, and server-side Flow Tape with sweep/block detection and dealer side inference — computed at trade arrival, not in your browser.
Can I cancel anytime?
Yes. Month-to-month, no contract. Cancel from your account settings. Access continues through the end of your billing period.
