Vendor disclosure: GEX Levels sells the Education Library and GEX Indicator — neither of which is an options flow scanner. This article compares flow scanners and explains where GEX Levels fits alongside them. We have an obvious interest in positioning our products favorably.

Best Options Flow Scanners in 2026: Prices, Features, and Honest Comparisons
An options flow scanner shows you live transactions — sweeps, blocks, unusual prints — as they happen. It's one of the most common tools in active options traders' workflows. But the products in this category vary enormously in price, depth, and focus. Here's how the main scanners compare, and how GEX Levels fits alongside (or instead of) them.
What an Options Flow Scanner Actually Does
An options flow scanner monitors the real-time tape of options transactions and surfaces prints that match filtering criteria — typically size (premium threshold), type (sweep vs. block), or statistical unusualness (activity relative to average daily volume).
What scanners show:
- Individual transactions — ticker, contract (strike + expiry), direction (call/put), size, premium paid
- Order type classification — sweep (multi-exchange, fast fill), block (single large order), split (one order broken into pieces)
- "Unusual" flags — when volume significantly exceeds OI or average daily volume
- Some scanners show sentiment scores, historical frequency, and "smart money" labels
What scanners don't inherently tell you:
- Whether the trade is opening or closing (critical for interpretation — a large put buy could be a bearish bet or a hedge being removed)
- The GEX context — where are dealers positioned, and does this flow confirm or contradict the structural level?
- The IV rank at the time of print (expensive options vs. cheap options changes the interpretation)
Main Options Flow Scanners in 2026
Unusual Whales
One of the most popular flow platforms. Shows live options flow, dark pool prints, political trading disclosures, and sector analysis. Published pricing starts at ~$50/month for the Pro tier. Broad platform — you may be paying for features you don't use. Strong community and social following. Good coverage of unusual OTM sweep activity.
Best for: Traders who want a comprehensive flow platform with broad feature coverage and social elements. Price: ~$50–70/month (public tiers).
Cheddar Flow
Focused specifically on options flow with a clean, minimal interface. Shows premium thresholds, sweep identification, and a heat map of activity by sector. Published pricing around $49–99/month depending on tier. Fewer features than Unusual Whales but more focused on the flow data itself without extras.
Best for: Traders who want clean flow data without noise. Price: ~$49–99/month.
Flowalgo
Real-time flow scanner with alerts, multi-leg detection, and a "whales" filter for large-premium prints. Also includes dark pool data. Published pricing ~$97/month. Known for its real-time alert system — useful for traders who want to be notified of prints matching specific criteria rather than monitoring a feed.
Best for: Alert-driven traders who want notifications on matching flow rather than continuous feed monitoring. Price: ~$97/month.
Market Chameleon
Broader market analysis platform that includes options analytics, flow data, earnings volatility data, and IV history. More data-heavy and analytics-focused than a pure flow scanner. Freemium model with paid tiers. Good for traders who want IV context, historical volatility analysis, and flow in one place.
Best for: Analytically inclined traders who want flow data plus deep IV and volatility analysis. Price: Freemium, paid tiers vary.
SpotGamma HIRO
Not a traditional flow scanner but worth including: SpotGamma's HIRO product shows real-time options flow aggregated and displayed as a directional indicator, with gamma exposure context. Different from transaction-level scanners — it shows the net effect of flow on dealer positioning rather than individual prints. Higher price point (~$49–149/month depending on tier).
Best for: Traders who want flow data contextualized within gamma positioning rather than raw transaction feeds. Price: From ~$49/month.

Where GEX Levels Fits
GEX Levels doesn't compete directly with any of these scanners — we don't show individual transaction prints. What we offer is different and complementary:
- GEX Indicator ($6.99/month) — draws the structural levels derived from gamma exposure (Call Wall, Put Wall, Gamma Flip) directly on your TradingView chart. Gives the structural context that tells you where to pay attention when reading flow prints. A scanner tells you a sweep happened at a certain strike; the GEX Indicator tells you whether that strike is near a key structural level or in the middle of nowhere.
- Education Library ($249.99 one-time) — explains how to interpret flow data correctly, including the GEX structural context, IV rank context, opening vs. closing interpretation, multi-leg detection, and the full analytical framework. If you're spending $50–100/month on a flow scanner but can't consistently interpret what you're seeing, the Library addresses the underlying problem.
The typical advanced 0DTE or options flow trader uses: a flow scanner (one of the above) + GEX structural levels (Indicator) together. The scanner shows you what's happening; the GEX context shows you where it's happening relative to the structural framework.
