GEX Tools Compared: Platforms, Scanners and Chart Indicators
Search for a gamma-exposure tool and you meet several shapes at once: subscription research platforms, web-based scanners, data APIs, and chart-native indicators. They overlap on the concept — mapping where options dealers are positioned — but differ sharply in where the levels live and how you work with them. This page compares those categories plainly, and shows where GEX Levels fits, without quoting any competitor's prices or exact specs, which change over time.
This page explains the concept. It shows no live numbers — the live map lives in the indicator, on TradingView and ATAS. Educational context only, not a signal.
Four shapes of the same job
A research platform is a destination: you open it to study positioning and read analysis inside its own dashboard. A scanner is a breadth tool for sweeping many tickers at once. A data feed or API is raw material you program against and render yourself. A chart-native indicator draws the levels directly on the chart you already trade. None is universally best — they suit different desks and routines, and many traders combine them.
GEX Levels is the chart-native indicator in that lineup. It reads the live options chain, computes dealer-positioning levels — Call Wall, Put Wall, Gamma Flip, Vol Trigger (zero-gamma), Zero DEX, Max Pain, Focus strikes, cluster and Battle zones, Vanna, Charm and Vega walls, a GEX profile, an Expected Move band and an NDX institutional set — and draws them, with a live context panel, on TradingView and natively on Sierra Chart, NinjaTrader, Quantower, MotiveWave and ATAS. One subscription and one access key cover every platform, and a free Morning Map publishes the prior session's index levels for NQ and ES daily.
How to choose by workflow
Start from where you want the levels to live. If you prefer one hub to read positioning and commentary, a research platform is built for that. If you screen dozens of symbols first, a scanner earns its place. If you want to own the pipeline and build your own visuals, an API is the right primitive. If you would rather see the levels on the exact chart you execute from, refreshed each session, a chart-native indicator fits that habit — that is the seat GEX Levels is designed for.
Whatever the shape, the levels themselves are a snapshot of the options chain and drift as it trades, so any honest tool treats them as evolving context rather than a fixed line. GEX Levels refreshes each session and is explicit that the levels are structure to interpret, not signals, forecasts, or trade instructions.
The categories side by side
| Tool | What it is | Where the levels live | Draws on your chart | Free way to see levels |
|---|---|---|---|---|
| GEX Levels | Chart-native gamma indicator | On the chart you trade | Yes — TradingView, Sierra, NinjaTrader, Quantower, MotiveWave, ATAS | Yes — free Morning Map (NQ & ES daily) |
| SpotGamma | Options-analytics research platform | Its own dashboard | No — read in its platform | See their site |
| MenthorQ | Options-levels / data service | Its own platform | Varies | See their site |
| GEXRadar | Web-based multi-asset gamma scanner | Its own web app | No — read in its app | See their site |
| TrendSpider | Charting platform with a gamma feature | Inside TrendSpider | Inside TrendSpider only | See their site |
| FlashAlpha | Gamma data / developer API | API or its own app | Only if you build it | See their site |
How to read this comparison honestly
This is a comparison of shapes, not a ranking that declares a winner. A research platform, a scanner, an API and an indicator each do something the others do not. The right choice is the one that matches your routine.
We do not state any competitor's current prices or exact feature set, because those change and we will not guess. The category labels reflect public positioning; verify specifics on each provider's own site.
Gamma levels describe where dealer positioning sits in the options chain. From any provider, they are a snapshot that goes stale as the chain trades — context to interpret, never a buy or sell instruction or a promise of a result.
Questions traders ask.
What is the best GEX indicator?
There is no single best — it depends on where you want the levels to live. Research platforms suit reading positioning in one hub, scanners suit sweeping many tickers, APIs suit building your own tooling, and chart-native indicators suit seeing the levels on the chart you already trade. GEX Levels is a chart-native indicator that draws dealer-positioning levels on TradingView and natively on Sierra Chart, NinjaTrader, Quantower, MotiveWave and ATAS, refreshed each session.
How is GEX Levels different from a research platform or scanner?
Delivery. A platform or scanner is a destination you open to read positioning; GEX Levels renders the levels on your execution chart and refreshes each session, so the context is in front of you at the price you are watching rather than in a separate window.
Do these tools tell you when to buy or sell?
No honest gamma tool does. The levels describe dealer positioning in the options chain — context, not signals. They are a snapshot that changes as the chain trades, which is why GEX Levels refreshes each session and leaves interpretation to you.
Can I see GEX Levels output before paying?
Yes. The free Morning Map publishes the prior completed session's index levels for NQ and ES every day, so you can see the shape and behaviour of the levels before deciding whether the live indicator fits your workflow.
Is this a buy or sell signal?
No. Everything on this page describes option-market structure — where dealer hedging concentrates — which is context on how a session is likely to behave, not a recommendation to buy or sell and not a prediction of direction. Educational and informational only; trading involves substantial risk of loss.
Where do the live levels come from?
The GEX Levels indicator computes them from the live options chain and draws them on your TradingView or ATAS chart, refreshed each session. This page explains the concept; the live map lives in the indicator, and the free Morning Map shows the prior session's index levels each day.

The concept is free to read. The live levels — call wall, put wall, gamma flip, the second-order greeks, the regime and more, refreshed every session — are built into the GEX Levels indicator for TradingView and ATAS. The free Morning Map shows the prior session's index levels each day.
