Best Dark Pool Scanner 2026: Complete Comparison

The dark pool scanner market has matured significantly. In 2026, retail traders have more options than ever for tracking institutional stock flow — and more confusion about which tool actually fits their workflow.

This comparison covers the five most relevant dark pool scanners: MobyTick, Unusual Whales, FlowAlgo, Cheddar Flow, and DarkPoolHeatmap.com. We evaluated each platform based on dark pool coverage, historical depth, whether the product is actually built around institutional stock flow instead of general trading chatter, pricing, and how useful the workflow is for a retail trader trying to understand where large money is active.

Disclosure: This comparison includes MobyTick as one of the products reviewed. MobyTick is a tool in this space, and we present its strengths and limitations alongside the alternatives.

How We Evaluated

Each platform was assessed on five criteria:

1. Dark Pool Coverage — Number of stocks tracked and breadth of dark pool data sources
2. Historical Depth — How far back the data goes for clustering and trend analysis
3. Specialization — Whether the product is built around institutional stock flow or is a general trading platform with dark pool data as an add-on
4. Pricing — Value relative to features and the target trader
5. Workflow Fit — How well the tool integrates into a practical retail trading process

Dark Pool Scanner Comparison Table

1. MobyTick — Best Overall for Dark Pool Research

Rating: 4.8 / 5 | Price: $19.99–$99.99/month

MobyTick is purpose-built for retail traders who want dark-pool-focused research. It tracks over 10,000 stocks with six-plus years of historical dark pool data, making it the deepest dedicated dark pool scanner on the market.

Where most tools stop at a data feed and leave you to map the levels yourself, MobyTick plots the top 10 dark pool prints directly on each ticker’s chart automatically, with full control over what’s shown. That means the institutional levels are visible the moment you open a name — you read them instead of rebuilding them by hand each session.

Strengths:

• 10,000+ stocks tracked with institutional print data
• 6+ years of historical dark pool data for clustering and trend analysis
• Built specifically around institutional prints, levels, and recurring price clusters
• Strong value pricing starting at $19.99/month
• Built-in charts that automatically plot the top 10 dark pool prints on each ticker by default, with full control over what’s displayed — no manual line-drawing required
• Full sector-level scan feature for identifying which industries have elevated institutional activity

Limitations:

• More specialized than broad all-in-one trading communities
• Best used alongside your normal charting workflow rather than as a social platform

Best for: Traders who want a dedicated dark pool research tool with wide coverage, historical depth, and a practical workflow — not just a general flow dashboard.

2. Unusual Whales — Broad Market Intelligence Platform

Rating: 4.1 / 5 | Price: $50/month

Unusual Whales is a well-known platform that includes dark pool data as part of a broader set of features covering options flow, unusual activity, and general market intelligence.

Strengths:

• Popular platform with strong brand recognition among retail traders
• Comprehensive options-flow tracking alongside dark pool data
• Useful for traders who want multiple data surfaces in one subscription

Limitations:

• Dark pool workflow is less specialized than a dedicated product like MobyTick
• At $50/month, it is not the cheapest option if dark pool research is your primary use case

Best for: Traders who want dark pool data alongside robust options-flow tracking in a single platform and don’t mind paying for broader features they may or may not use.

3. DarkPoolHeatmap.com — Best Free Starting Point

Rating: 3.9 / 5 | Price: Free

DarkPoolHeatmap.com offers a free, fast way to see which sectors and individual tickers are showing active dark pool flow. DarkPoolHeatmap.com is owned and operated by MobyTick, serving as a free entry point into the MobyTick ecosystem.

Limitations:

• Not a full premium research workflow
• Less historical depth and fewer advanced features than paid alternatives
• No alerts, watchlists, or charts with the prints plotted on them

Best for: Newcomers to dark pool data and traders who want a free starting point before upgrading to a deeper research tool.

4. FlowAlgo — Premium Alert-Focused Platform

Rating: 3.9 / 5 | Price: $149/month

FlowAlgo is a premium platform that delivers real-time flow alerts with dark pool data included in its feature stack. It appeals to traders who want an alert-driven workflow and are willing to pay for a premium experience.

Strengths:

• Established brand in the flow-data category
• Real-time-style alerting for active traders
• Premium user interface and experience

Limitations:

• At $149/month, it is significantly more expensive than alternatives
• Less compelling value if your primary interest is dark pool stock-level context rather than general flow monitoring

Best for: Traders with larger budgets who want a premium, alert-driven workflow and don’t mind paying a premium for the brand and interface.

5. Cheddar Flow — Options and Chart-Oriented Platform

Rating: 3.8 / 5 | Price: $85–$99/month

Cheddar Flow combines dark pool data with options flow tracking in a chart-oriented interface. It is useful for traders who want both data types in one platform.

Strengths:

• Recognized among retail flow traders
• Combines dark pool and options context in a single tool
• Solid chart integration

Limitations:

• Less specialized if your core use case is institutional print analysis
• More expensive than MobyTick despite offering less dedicated dark pool depth

Best for: Traders who want dark pool and options data together and prefer a more general trading platform.

Stock Coverage and Sector Scan Comparison

One of the most practical differences between these platforms is how many stocks they track and whether they offer dedicated sector-level scans:

Stock coverage matters because many scanners only track the most liquid names. If you watch small-caps, mid-caps, or less-followed sectors, the actual ticker coverage of your chosen platform becomes a practical constraint. MobyTick leads with 10,000+ stocks and is one of the few platforms where the coverage extends meaningfully beyond mega-cap and large-cap names into mid-caps and smaller names.

For sector scanning, MobyTick and DarkPoolHeatmap.com offer the most usable sector-level views. MobyTick provides a full color-coded sector heatmap with per-sector ticker drill-down. DarkPoolHeatmap.com gives a free, simplified version of the same data. Unusual Whales includes sector filters but the workflow is less visual and more list-based. FlowAlgo and Cheddar Flow have limited sector categorization — useful for finding major sector activity but less effective for identifying specific sub-sector rotation.
