Know if dealer hedging fights the move — or fuels it.
Every day, options dealers are forced to buy and sell the index your future tracks — not because they want to, but to stay hedged. GEX maps that pressure, strike by strike, before you enter. This is the dashboard, running below on simulated data.
The forced flows behind the tape
When traders buy options, dealers take the other side — and dealers do not gamble. They hedge, mechanically, all session long. Gamma exposure (GEX) aggregates that obligation across every strike: above the zero-gamma level their hedging absorbs moves; below it, it amplifies them.
For a futures trader, that is one piece of context worth having before every session: is today a mean-reversion tape or a trend tape — and where are the walls likely to slow it down?
The full theory, in plain words → our GEX guideFrom the options chain to three lines on your chart
Read the chain
The app pulls the full CBOE options chain — open interest and gamma for every strike and expiry, refreshed automatically.
Aggregate the exposure
Per-strike dealer gamma is summed into a profile: net GEX, plus VEX, CEX and DEX if you want the other Greeks.
Draw the levels that matter
Call wall, put wall, zero-gamma flip — three lines, straight on the dashboard, updated as the chain moves.
Move the price. Watch dealers switch sides.
This is the core read, in your hands: drag the price across the profile and watch the regime flip at zero-gamma — from a tape where hedging absorbs your moves to one where it chases them.
On the desktop, it runs on the real chain
Everything on this page is simulated — deliberately. In the app, the same dashboard runs on the live CBOE chain (about 15 minutes delayed, which for a structural read like dealer positioning changes little — we would rather tell you that than let you find out), refreshes on its own, and adds VEX, CEX and DEX next to GEX. It ships in the one $29/mo plan with the footprint, the heatmap and the DOM — not as an add-on.
Frequently asked questions
Is the GEX dashboard included in the $29 plan?
Yes. Senzoukria has one plan — footprint, heatmap, DOM and the GEX suite (GEX, VEX, CEX, DEX) are all in it, on the desktop app. The 14-day trial includes everything too.
Where does the options data come from?
From the CBOE options chain, refreshed automatically in the app. Options data is roughly 15 minutes delayed — which matters little for GEX: dealer positioning is a structural read that shifts over hours, not ticks. We say this upfront because you would notice it anyway.
Do I need an options broker account to use GEX?
No. GEX is context for your futures trading — it tells you where dealer hedging sits on the index your future tracks. Your Rithmic / Apex / NinjaTrader futures setup stays exactly as it is; no options account is involved.
Is the data on this page real?
No — every chart on this page runs on simulated data, and says so on its badge. We never show numbers a visitor could mistake for real levels. The desktop app runs the same renderers on the real, auto-refreshing chain.
