Features and specs

What each product offers, as listed by its team.

Dokku 5 features
ChartGEX 5 features
  • Ease of Use
    Dokku provides simple commands and clear documentation, making it straightforward to deploy, manage, and scale applications using a process similar to Heroku.
  • Heroku Compatibility
    Dokku uses a Heroku-like buildpack system, which allows users to deploy applications with ease if they are already familiar with Heroku.
  • Cost-Effective
    Being an open-source project, Dokku itself is free to use, which can significantly reduce the cost of deploying applications compared to using premium services.
  • Customizability
    As an open-source tool, Dokku allows for extensive customization according to user needs, offering flexibility in deployment settings and configurations.
  • Plugin System
    Dokku supports a wide range of plugins, enabling users to extend its functionality easily, such as adding database support, monitoring capabilities, and more.

Possible disadvantages

  • Initial Setup Complexity
    Setting up Dokku for the first time might be challenging, especially for users with limited experience in server management and Linux administration.
  • Limited Built-In Features
    Compared to fully-managed PaaS solutions, Dokku has fewer built-in features, potentially requiring more effort to implement certain functionalities such as load balancing and extensive monitoring.
  • Scalability Challenges
    While Dokku supports basic scaling, it might not handle extensive scaling needs as efficiently as more robust enterprise-level solutions.
  • Resource Management
    Dokku's resource management capabilities are limited compared to dedicated orchestration tools like Kubernetes, making it less suitable for complex and large-scale application deployments.
  • Community Support
    Even though Dokku has a growing community, it is not as large or as active as some of the more popular platforms, which can limit the availability of community-driven support and resources.
  • Visual Chart Pattern Recognition
    ChartGEX provides automated chart pattern recognition for stocks and other financial instruments, helping traders quickly identify technical patterns without manually scanning through hundreds of charts.
  • Time-Saving for Technical Traders
    By automating the process of detecting chart patterns such as triangles, wedges, head and shoulders, and other formations, ChartGEX saves traders significant time that would otherwise be spent on manual chart analysis.
  • User-Friendly Interface
    The platform is designed to be accessible and easy to navigate, making it suitable for both beginner and experienced traders who want to incorporate technical pattern analysis into their trading strategies.
  • Multiple Pattern Detection
    ChartGEX can identify a variety of classic chart patterns across different timeframes, giving traders a broader view of potential trading opportunities based on well-known technical formations.
  • Screening and Filtering Capabilities
    The tool allows users to screen and filter stocks based on specific chart patterns, enabling traders to focus on the setups that match their particular trading style and criteria.

Possible disadvantages

  • Reliance on Technical Patterns Alone
    ChartGEX focuses primarily on chart pattern recognition, which may give traders a false sense of certainty. Technical patterns do not guarantee future price movements and should ideally be combined with fundamental analysis and other indicators.
  • Limited Free Features
    Like many trading tools, ChartGEX may restrict access to advanced features behind a paid subscription, which can be a barrier for casual traders or those just starting out who want to fully evaluate the platform.
  • Pattern Detection Accuracy Concerns
    Automated pattern recognition is not always perfectly accurate. The algorithm may occasionally identify patterns that experienced traders would not consider valid, potentially leading to false signals and poor trading decisions.
  • Niche Tool with Limited Broader Analysis
    ChartGEX is specialized in chart pattern detection and may lack comprehensive features found in more full-featured trading platforms, such as fundamental data, news integration, backtesting, or portfolio management tools.
  • Relatively Lesser-Known Platform
    Compared to established platforms like TradingView or Finviz, ChartGEX has a smaller user community, which means fewer user-generated resources, tutorials, and peer discussions to help new users get the most out of the tool.

Questions & Answers

As answered by people managing Dokku and ChartGEX.

What makes your product unique?

ChartGEX's answer:

Most options tools show you open interest and volume — 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 — 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 — 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 — 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 — TradingView, FinViz, OptionCharts.io — 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 — 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 — 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 — gamma walls, flip points, magnet strikes — 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 — 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 — open interest charts, put/call ratios — 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 — 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 — 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 — 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 — 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.
