Native study — Sierra Chart

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.

  1. Pick a package above. The DLL is precompiled for 64-bit Sierra Chart — fastest path, nothing to build. The source package is the always-works path: it compiles on your own Sierra Chart, whatever the version.
  2. DLL route: close Sierra Chart, copy GexLevelsStudy_64.dll into your Data folder (Global Settings → General → Paths shows it), restart. Skip to the last step.
  3. Source route: copy GexLevelsStudy.cpp into your ACS_Source folder, then Analysis → Build Custom Studies DLL → Build (or Remote Build if you don't have the local compiler — one file is all it needs). Wait for the “build succeeded” message. If you have a fear_percentiles_v1.h left over from an older download, delete it — it is now built into the .cpp.
  4. 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.
The DLL is compiled against a current 64-bit Sierra Chart; a much older or 32-bit install may refuse it — in that case use the source package, same study, same features. If neither path works on your setup, open a ticket and we will help.

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.
