Gamma Exposure (GEX)

The dealers' map of the day.
Now you read it too.

Every option position has to be hedged, and the sum of those hedges shapes how the tape moves. GEX opens on the read — bullish, bearish or neutral, and why — then shows the levels underneath it: where dealers buy, where they sell, where the regime flips, and how far today is expected to travel.

Open on the read

The read first. Then the levels.

The panel opens with the AI market read for the ticker — its bias in the card, a sentence on what dealers are positioned to do, and a note that it re-runs when you refresh. Underneath: call wall, put wall, gamma flip, the expected move as a full range, net GEX, the biggest positive and negative strikes, and put/call sentiment. Each level has a plain-English tooltip and a switch that draws it on the chart.

  • Bias carried in the card, re-run on refresh
  • Eight levels, each explained on hover
  • Toggle any level onto the price chart
Call wall · Put wall

Mechanical support and resistance.

The call wall is the strike carrying the most dealer call gamma — the ceiling they sell into. The put wall is the floor they buy. Both draw on the candle chart, both sit flagged in the strike table with their gamma in dollars, and the heatmap and strike profile centre on them, so the part of the chain that matters is on screen without hunting for it.

  • Walls drawn on the candle chart, 1m to 1d
  • Heatmap, profile and table auto-centre on the walls
  • Focus window: walls ± 5 strikes, or the whole chain
Gamma flip · Expected move

The regime line, and how far today can travel.

Above the flip, dealer hedging dampens moves and the tape grinds. Below it, hedging amplifies them. GEX interpolates the flip across the exact strike where cumulative gamma crosses zero, with a noise floor so it doesn't flicker on quiet strikes. The expected move shows the full implied one-day range, high to low, and draws both bands on the chart.

  • Flip interpolated between strikes, with a noise floor
  • Expected move as a full range, both bands on the chart
  • Expirations by class — All, 0DTE, Weekly, Monthly — or a single date
Strike × expiration heatmap

See the whole term structure at once.

Every strike and every expiration in one diverging-colour grid: green where dealers are long gamma, red where they're short. Wall rows carry their chips, the grid centres on the walls, and any cell shows net GEX, open interest and volume on hover. Free on SPY and QQQ; every ticker on Trader.

  • Sticky headers, same focus window as the table
  • Wall rows flagged CW and PW
  • Free on SPY and QQQ, every ticker on Trader
Share the read

Send the map, not a screenshot.

The Share button on every GEX read makes a public snapshot page with a proper preview card, a ready-made post for X, or the chart as an image. Drop the link in a group chat and it unfurls with the levels.

Then act on it

Explain it. Or scan it.

Two buttons under the levels. Explain this setup sends the walls, the flip, net GEX and the expected move to the AI Advisor, which tells you what the regime means today and which structures fit it. Scan for plays at these levels opens the Scanner on the same ticker with the read already applied. And every weekday at 9:00 ET a briefing with the SPY, QQQ and IWM picture lands in your inbox, on every plan.

  • Explain this setup → the Advisor, context filled in
  • Scan for plays at these levels → the Scanner
  • 9:00 ET gamma briefing for SPY, QQQ and IWM, every plan
On your phone

GEX in your hand.

A slim header, the expiration row, the read, and a 2×2 board that shows which levels are on the chart. Explain this setup sits one tap down, the compact metrics strip carries net GEX and sentiment, and the app tab bar keeps the Scanner and the Advisor one tap away.
