Decode dealer gamma.

What you're seeing

Dealer gamma is the gravity of the market.

Every option you trade has a counter-party — usually a market maker. To stay neutral they hedge with the underlying. That hedging activity creates a measurable pull on price. If you can see where that pull is strongest, you can predict where price will chop, where it'll break out, and where it'll pin into the close.

GEX — Gamma Exposure

The total dealer hedging pressure at every strike. Positive GEX dampens volatility (price gets pulled toward big strikes). Negative GEX amplifies it (every move feeds itself).

VEX — Vanna Exposure

How dealer delta-hedging changes when implied vol shifts. Big vanna walls predict where IV expansion will accelerate or fade a move.

The Flip Point

The strike where net dealer gamma crosses zero. Above it: mean-reverting tape. Below it: trending tape. Knowing which regime you're in changes everything.

The Heatseeker

One screen. Every strike. Every expiry.

A strike × expiry grid showing dealer GEX or VEX in real dollars. Green is positive (dealers long gamma — mean-reverting). Purple is negative (dealers short gamma — trending). The yellow row is your spot. Toggle between GEX and VEX with one click.

Illustrative snapshot. Live data shows ~200 strikes × 8 expiries refreshed every 60 seconds.
Why it works

From gut-feel to data-driven.

Most SPX traders read price action and hope. The desks read the option chain and know. Heatseeker shows you the same gamma map the institutional desks see — refreshed every 60 seconds.

Avoid the chop zones

When dealers are long gamma above spot, expect mean-reversion. Stop fighting the pin — sell premium into it instead.

Catch the flip

When negative GEX flips above spot, hedging flows reverse and ranges expand. Long gamma + directional bias = your best risk/reward.

Trade with the magnets

The biggest GEX strike acts like a magnet into expiry. SPX 0DTE traders use this to time entries minutes before pin events.

Don't get blindsided

When VEX spikes negative below spot, an IV crush rip is loaded. Most retail traders are short premium into this. Don't be them.

FAQ

Common questions.

What exactly does Heatseeker show me?+

A strike × expiry grid showing dealer Gamma Exposure (GEX) or Vanna Exposure (VEX) in dollar terms for SPX, SPY, and QQQ. Green = positive, purple = negative. The brighter the cell, the more weight at that strike/expiry combination.

How fresh is the data?+

60-second refresh during market hours. Off-hours we keep the previous close cached so you can study positioning without waiting for the bell.

What's the data source?+

Real Polygon.io option chain snapshots. We compute every Greek (gamma, vanna, charm, vega) ourselves using Black-Scholes — no third-party black box.

Do I need to know what GEX is to use it?+

No. The site has a built-in primer (read above), and the heatmap is designed so the colors tell the story: bright green = pin level, bright purple = breakout level.

How do I get in?+

Buy on Whop (link above). Whop emails you a license key. Paste it on the sign-in page and you're in immediately.

What's coming next?+

Indicators for TradingView/ThinkOrSwim, Discord + phone alerts on key levels, full 0DTE expiry mode, and a multi-account dashboard for prop firms. All included for active subscribers.
