Dealer gravity bends price

Gamma, delta, vanna and charm, strike by strike: the walls dealers defend and the flip where their hedging turns.

Heat Tracker · Flow

Every print, in orbit

The option tape read minute by minute: where premium lands, which side it is on, and where the pressure builds.

THE TERMINAL

Read the levels before price finds them

The walls, the heat, the positioning and the skew behind every move. Six views from the live dashboard.

See where dealers have to hedge

Net gamma, delta, vanna and charm mapped strike by strike from the whole chain — not a sampled snapshot. The walls that pin price and the flip level that ends the pinning, both on one profile.

HOW IT WORKS

One session, start to finish

A trading day with the terminal, in the order it happens. Every number on these screens is computed here, from the full option chain — in time to use it, not after.

  1. 01 Before the open

    Start with the map

    Open Exposure and the walls are already drawn: dealer gamma, delta, vanna and charm, summed strike by strike from the whole chain, with IV solved from each contract's own bid/ask mid. Call wall, put wall, flip. For QQQ, the Daily Trade Plan writes the session up before the bell.

  2. 02 At the bell

    Watch the walls get hit

    The Heat Tracker lights every strike where contracts print, minute by minute, with price running across it. A wall that holds and a wall that gives way look nothing alike — and you see which it is while it is happening, not in the recap.

    • Heat Tracker
    • Heat Ladder
    • Scanner
  3. 03 Through the session

    Read what the tape is paying for

    Every print with its size and the side it hit. Money piling into puts under spot, the flip shifting, the wings bidding up: the flow and skew views say where the pressure is building and how much the market is paying for protection.

  4. 04 After the close

    Carry it to tomorrow

    The closed session settles into the book you open the next morning. Export its levels as a DeepChart file (QQQ → NQ, SPX → ES), run our invite-only scripts on TradingView, and set an alert on the level you care about — it fires when spot crosses it.

FAQ

Questions, answered

GEX (gamma exposure) estimates how much dealers must buy or sell to stay hedged as price moves. It reveals the levels where the market gets "pinned" or accelerates — one of the most reliable maps of intraday behaviour.

No. The signals are readable at a glance, and our Knowledge Base walks you from the basics to advanced positioning. Most users are trading with the data within their first session.

Index products (SPX, SPY, NDX, QQQ) plus every US-listed equity and ETF with listed options — any symbol, on every plan.

Yes. Premium is free to try for 7 days — the live terminal, every Premium module. Choose Premium on the monthly term in the pricing table to start; after the seven days it renews at the monthly Premium price unless you cancel from your Whop account.

Premium is real time — the entire option chain, every strike and every expiry, recomputed every two seconds for the whole session. What you read is the book as it stands, not a snapshot from a minute ago. Basic reads the market-data views at the last close; the 7-day trial is full Premium, live.

You can stop your subscription renewing at any time from your Whop account, where it is billed. It then runs to the end of the period you have paid for, and payments are non-refundable — including unused time on an annual plan. The 7-day Premium trial is there to try the product first.

No. Quantdecay provides market data and analytics for research and education. Nothing here is a recommendation to buy or sell any security. You are responsible for your own trading decisions.
