Why it matters
Positioning is never static
Every time price crosses a strike, dealer exposure re-weights. ITMatrixHQ recomputes the full map as the session unfolds, so you read the market as it stands now, not as it closed.
The terminal
Every angle of one market
01GEX Matrix
Exposure, strike by strike
Dealer gamma for every strike across the next several expirations, colored by sign and magnitude. Replay the session or open any past day and watch positioning build.
- Heat or profile, shares or dollars
- Walls, control node, flip
- Alerts on any cell
02Surface
The topology of exposure
Strike and expiration as one surface. See where exposure concentrates, where it inverts, and how the shape changes as flows reach the book.
- Gamma exposure or implied vol
- By strike, moneyness or delta
- Replays with the session
03Charts
Price, in context
Candles drawn over the GEX heatmap and key levels, so every move reads against the positioning beneath it. Replay any session bar by bar.
- GEX pillars and key levels
- Off-exchange zones on price
- Studies, drawings, saved layouts
04Workspace
One workspace, in lockstep
Grid, profile and chart linked to one symbol and one clock. Arrange them your way, then replay any day with every panel moving together.
- Widgets linked by color group
- Saved workspaces and tabs
- Popouts and multi-window
Capabilities
Depth beyond gamma
Volatility, the options tape, off-exchange structure and your own trade record, in one terminal on one clock.
Volatility API
Implied vol from our own engine: the full surface by strike, moneyness or delta, skew and term slices, and the ATM term structure.
Off-exchange API
Large prints with their evidence, persistent zones drawn on the chart, and a market-wide scanner with breadth.
Options Lab
The options tape for the market, a watchlist or one symbol, a scanner that ranks contracts, and each contract charted with its greeks.
Unusual activity
Eleven detectors score each event, from sweeps and blocks to 0DTE bursts, each with its prints.
0DTE
Same-day expiries read on their own: the 0DTE column on the grid and 0DTE bursts in the flow.
Intraday replay
Scrub any past session. Matrix, surface, charts and off-exchange move on one clock.
Journal & watchlists API
Log trades or import a broker statement, then review them by day, ticker and session.
Fundamentals API
Statements, balance sheet, short interest and distributions on the stock page.
News Soon
A per-symbol digest on the dashboard and stock page; the full view with a market brief is next.
Also available through the ITMatrixHQ REST API. Shipping to the terminal next.

What is ITMatrixHQ?
ITMatrixHQ is an options market-structure terminal. It visualizes gamma exposure (GEX) across strikes and expirations, streams live charts and option chains, and lets you build a custom workspace of linked widgets — all in one screen, updating through the trading session.
What is GEX and why does it matter?
GEX, or gamma exposure, estimates how options dealers must hedge as price moves. When dealers are long gamma their hedging dampens volatility and can pin price; when they are short gamma it amplifies moves. Reading that structure helps you understand whether the tape is likely to be sticky or slippery. See our Learn section for a full primer.
What is the difference between the plans?
Charts is the standalone charting app on its own — $29.99 a month, billed monthly, with the GEX overlay included; free accounts can use it on a 15-minute delay. Basic gives you the full set of views as fixed single-page layouts, and includes the charts product. Pro unlocks the modular workspace canvas — add, resize, link and save your own widget layouts — along with streaming data, index data (SPX, NDX, VIX) and the API Explorer. The API plan (API Pro) is the full API on its own, with or without a web plan.
Is there an API?
Yes. The ITMatrixHQ API is plain REST and JSON — one key, one base URL, and the same numbers the terminal shows: GEX by strike, options analytics and implied volatility, off-exchange activity, prices, fundamentals, and your own journal and watchlists. API Explorer is included with Pro; API Pro is its own plan. Official SDKs for Python (itmatrix) and TypeScript (@itmatrixhq/core) wrap it in typed models, with more languages coming soon. Live streaming is coming soon. Index data, news and social feeds, and the options flow tape stay in the terminal. API access is for non-professional use only.
How often does the data update?
On Pro, live data streams into the terminal through the session and the GEX grid refreshes on a short cadence. Free access shows a single daily snapshot, taken at 9am, of the GEX view plus low-frequency charts, for a limited set of symbols; free accounts can also use the charting app on a 15-minute delay. Exact refresh rates depend on your plan.
