The GEX map, native on Sierra Chart.
The same gamma-exposure structure the Chrome extension draws on TradingView — as a native ACSIL study on your Sierra Chart charts. Labeled level lines, zone rectangles, second-order greeks, the NDX institutional set and a live status panel. One subscription, one license key, every platform.
Requires Sierra Chart on Windows and an active GEX Levels Indicator subscription. Built on Sierra's own HTTP layer — no third-party DLL. Already subscribed? Your existing key works.
Everything the extension draws — natively.
No browser, no overlay: a compiled ACSIL study talking directly to the GEX Levels backend over Sierra's own HTTP layer. Levels refresh on your schedule, or lock to the session open.
The full level map
Call and Put Walls, Gamma Flip, Vol Trigger, Max Pain, Focus confluence levels, open-interest walls, Zero DEX, and wall extenders ranked from the dense gamma profile.
Volatility structure
The Daily Volatility Zones — expected-move bands frozen at the session open on the server, so every platform draws the identical geometry — plus the unstable corridor between VT/HVL and Gamma Flip, and the Battle Zone with its value clusters.
Two crowds, one chart
The NDX institutional set draws alongside the QQQ-derived retail map. Where they agree the level is stronger; where they split, the gap itself is information.
Live status panel
Regime, Net GEX, spot-vs-flip, ATM IV, hedging pressure, session flow. In Locked mode the map stays frozen while the panel keeps describing the present.
Zone rectangles & labeled lines
Value zones drawn as rectangles, every level a labeled horizontal line — rendered with Sierra's native drawing tools, not a bitmap overlay.
Locked at open
Anchor the map to the session open — the identical snapshot the Chrome extension and gex-levels.com/levels serve, so every surface tells the same story.
Questions traders actually ask.
Do I need a separate subscription for Sierra Chart?
No. One Indicator subscription covers the Chrome extension on TradingView, the TradingView Pine companion, ATAS, and the native ports. Your existing license key works as-is on Sierra Chart.
Do I need any third-party DLL?
No. The study is built from source with Sierra Chart's own custom-studies compiler and talks over Sierra's built-in HTTP layer. Nothing else is required.
Will the levels match my Chrome extension exactly?
Yes — same backend, same computation, same session snapshot in Locked mode. If two surfaces ever disagree, that is a bug we want to hear about.
Which Sierra Chart package do I need?
Any package that allows custom ACSIL studies. The levels come from the GEX Levels backend over your subscription, not from your Sierra data feed.
Is this a signal tool?
No. GEX Levels describes option-market structure — where dealer hedging concentrates. It never tells you to buy or sell, and nothing in it is a prediction or advice.
Download & install — about five minutes.
- Download the package above and extract it (right-click → Extract All). It
contains a single
GexLevelsStudy.cpp— the study is fully self-contained — plus theREADME. - Copy
GexLevelsStudy.cppinto your Sierra ChartACS_Sourcefolder (Global Settings → General → Data/Trade Data Folder shows the path). If you have afear_percentiles_v1.hleft over from an older download, delete it — it is now built into the.cpp. - In Sierra Chart: Analysis → Build Custom Studies DLL → Build (or
Remote Build if you don't have the local compiler), select
GexLevelsStudy.cppand build. One file is all Remote Build needs. Wait for the “build succeeded” message. - On a chart: Analysis → Studies…, add GEX Levels, paste the license key from your dashboard, set your symbol (NQ, ES, QQQ, SPY…) and click OK.
One map. Every platform.
Subscribe once, draw the same gamma structure on TradingView, ATAS, Sierra Chart and the rest — anchored to the same session open everywhere.
