ChartGEX is an options analytics platform built for traders who want to understand the mechanical forces behind market price movement, not just where price has been, but where it's structurally obligated to go.

At the core of ChartGEX is Gamma Exposure (GEX) analysis. Market makers who sell options are required to delta-hedge their positions, and that hedging creates predictable, repeatable behavior at specific strike levels. ChartGEX quantifies these obligations across every listed strike and expiration, surfacing the gamma walls, flip points, and magnet levels that actually drive intraday price action.

Beyond GEX, the platform tracks Vanna and Charm flows the two Greeks that determine when a slow grind turns into a vol-driven acceleration or a sharp sell-off exhausts itself. These are the signals institutions use to anticipate moves around OpEx and 0DTE expiration cycles.

ChartGEX also includes an ML prediction layer that synthesizes gamma positioning, options flow imbalances, and volatility regime data into calibrated directional forecasts tied to specific strike-level mechanics. It's designed to pressure-test your trade thesis, not replace it.

Data is sourced from institutional-grade feeds (OPRA-level), calculated in real time throughout the session, and presented in a dashboard built for practical use. Whether you're running a 0DTE scalp or managing a multi-day swing, ChartGEX gives you the structural context to size with confidence and filter out low-quality setups.

Questions & Answers

As answered by people managing Chart.js and ChartGEX.

What makes your product unique?

ChartGEX's answer:

Most options tools show you open interest and volume โ€” and stop there. ChartGEX goes a layer deeper by quantifying what dealers are actually forced to do because of that positioning. That's the core difference.

When a market maker sells options, they have to delta-hedge continuously. That hedging isn't random โ€” it creates mechanical buying and selling pressure at specific strikes. ChartGEX maps those obligations in real time, so you can see where price is likely to get pinned, repelled, or accelerated before it happens โ€” not after.

Beyond GEX, the platform layers in Vanna and Charm flow analysis, which tell you how dealer hedging behavior shifts as volatility moves and time decays. That's what drives the 2pm melt-ups, the OpEx pins, the charm-driven drifts that catch most traders off guard. ChartGEX surfaces those dynamics explicitly.

Then there's the ML prediction layer โ€” directional forecasts calibrated to specific strike-level mechanics, not generic trend signals. It synthesizes gamma positioning, flow imbalances, and vol regime data into something actionable: a structural lean that either aligns with your thesis or tells you to wait.

The data is sourced from institutional-grade feeds (OPRA-level), updated continuously throughout the session. That's not standard for retail-facing tools. Most platforms run on delayed snapshots. ChartGEX doesn't.

Why should a person choose your product over its competitors?

ChartGEX's answer:

The alternatives โ€” TradingView, FinViz, OptionCharts.io โ€” are useful tools, but they're built around different assumptions about how markets work. They focus on price history, technical patterns, and static open interest. ChartGEX is built around market structure: specifically, what options dealers are obligated to do based on their current hedging positions.

That distinction matters in practice. GEX walls don't show up on a candlestick chart. The gamma flip level that determines whether dealers suppress or amplify the next move isn't something a moving average will tell you. ChartGEX gives you that structural context as a first-class input โ€” not an afterthought.

A few specific reasons traders choose ChartGEX over the alternatives:

The GEX analysis is calculated from real institutional-grade data, not delayed retail feeds. That matters especially for 0DTE and intraday trading where stale data is worse than no data.

Vanna and Charm flows are included. Most competing tools don't touch these at all, even though they're central to understanding why price accelerates into OpEx or why vol expansion doesn't follow through.

The ML prediction layer adds a directional signal that's tied to structural positioning, not just historical price behavior. It's a pressure test on your thesis, not a replacement for it.

And at $29/month after a free trial, the price point is a fraction of what institutional analytics desks charge for similar data. For independent traders and small prop shops, ChartGEX is the only place this level of analysis is even accessible.

How would you describe the primary audience of your product?

ChartGEX's answer:

ChartGEX is built for traders who already have a baseline understanding of options markets and want to go deeper into the mechanics of price movement. It's not a beginner platform โ€” and it doesn't try to be.

The core audience breaks down into a few groups:

Active retail traders who trade SPX, SPY, QQQ, or individual equities with options exposure. They're typically running 0DTE or short-dated strategies and need real-time structural levels โ€” gamma walls, flip points, magnet strikes โ€” rather than lagging indicators.

Independent professionals and prop traders who manage meaningful position sizes and need data that holds up under pressure. For them, the cost of a bad read on market structure far exceeds a $29/month subscription.

Systematic traders who are building edge into their process. ChartGEX's API access makes it straightforward to pull GEX, Vanna, and Charm data directly into a trading model or alerting system.

What ties them all together is a frustration with tools that explain what happened after the fact. ChartGEX is specifically for traders who want to understand the structural forces shaping price before the move develops โ€” not after it's already played out on the tape.

What's the story behind your product?

ChartGEX's answer:

ChartGEX started from a pretty simple observation: the options market is the most information-rich market in the world, and most traders are using maybe 5% of what's actually in there.

The tools that existed were either too basic โ€” open interest charts, put/call ratios โ€” or locked behind institutional infrastructure that costs thousands of dollars a month. The analytics that serious options desks rely on, things like gamma exposure mapping, Vanna flow modeling, charm decay โ€” those just weren't accessible to independent traders.

The goal was to change that. Not by dumbing the data down, but by building an interface that makes complex positioning data actually usable in a live trading session. You shouldn't need a quant background to know whether the current gamma regime favors fading moves or riding them. That answer should be visible in under a minute.

So ChartGEX was built with that constraint in mind: institutional-grade data, engineered for practical daily use. The ML layer came later, as a way to synthesize the positioning signals into something that pressure-tests your existing thesis rather than replacing your judgment entirely.

It's still early. The platform keeps evolving based on direct feedback from the traders using it. But the core belief hasn't changed โ€” every trader deserves access to the same structural intelligence that institutions use to make decisions.

Which are the primary technologies used for building your product?

ChartGEX's answer:

The frontend is built on Next.js, which gives us server-side rendering where it matters for performance and a clean component structure for the dashboard UI. The charting layer handles real-time data visualization across multiple instruments and expiration cycles simultaneously, so responsiveness under load was a key design constraint from the start.

On the data side, the platform ingests options chain data from institutional-grade feeds โ€” open interest, volume, implied volatility surfaces, and Greeks across every listed strike. The GEX, Vanna, and Charm calculations run continuously throughout the session, which requires a backend infrastructure that can process and serve that data with minimal latency.

The ML prediction layer is a separate model pipeline trained on gamma positioning, options flow, and volatility regime data. It's designed to output calibrated directional forecasts rather than binary signals โ€” which means the model architecture prioritizes reliability over novelty.

The API is built to be developer-friendly for systematic traders who want to pull positioning data directly into their own workflows or alerting systems.

    A must-have tool for options traders who want a real edge

    ChartGEX has genuinely changed how I approach trading decisions. Before using it, understanding gamma exposure and options flow felt like trying to read a map without a legend. ChartGEX makes all of that visual, intuitive, and actionable.

    The GEX and DEX visualizations are clear and update in a way that actually helps you understand where key price levels are and how market makers are positioned. The options flow data is particularly useful, being able to see unusual activity and large orders in real time gives you context that most retail traders simply don't have access to.

    The UI is clean and well-organized. Everything loads quickly, and the charting tools are responsive. I appreciate that the platform doesn't overwhelm you with unnecessary noise; it surfaces what matters most for making smarter entries and exits.

    The learning curve is minimal if you already have a basic understanding of options Greeks. For newer traders, there are enough contextual cues to build that understanding over time. I've found myself relying on ChartGEX before nearly every major trade to sanity-check my thesis against the options market structure.

    Overall, this is one of the most practical analytics tools I've added to my workflow. It fills a gap that most charting platforms completely ignore.
