Unusual Whales Review
Unusual Whales is a real-time options flow and market data platform built around one core product: a live feed of every options trade executed across all US options exchanges, filterable down to execution character. It is the tool to beat in retail flow tracking, priced well below what this data historically cost, and the right buy for an options trader who acts on intraday signals. A trader who does not watch flow live has little reason to pay for it, and anyone trading outside US-listed options has no reason at all.
The Flow Feed
The feed is the platform, and everything else orbits it. According to the platform’s documentation, the flow tool captures trade details for all options orders transacted across every US options exchange, with the core trade data (ticker, contract, bid-ask, spot, size, premium, open interest, volume, flags) supplied directly by the executing exchange. Derived fields like days to expiration and the percentage distance between strike and stock price are calculated by the platform and shown alongside.
The column set is where the depth shows. Each print carries time, side, contract, DTE, stock price at execution, percent difference to strike, the NBBO bid-ask at the time of the trade, the fill price, size, premium, open interest, volume, implied volatility, and the exchange-attached code and flags. Side labeling is rule-based: a fill at or closer to the NBBO ask is marked a buy, a fill at or closer to the bid is marked a sell. That is exactly the raw material needed for the side-of-spread reading described in how to read options flow, presented per print rather than left for the trader to reconstruct.
Two documented quirks deserve attention before anyone trades off the labels. Mid-price fills are currently labeled as buys, and the documentation itself warns that the side markers are an estimation not to be traded on alone, since a buy order is not necessarily an opening buy. Both caveats are honest, and both matter: mid prints resist directional reading in any feed, and a platform that flags its own labeling limits is more trustworthy than one that pretends the tape is unambiguous. There is also a sorting threshold worth knowing: sorting the feed by anything other than size restricts results to trades of at least $25,000 in premium or at least 150 contracts.
Multi-leg orders are identified in the feed, and clicking one preloads the trade into the built-in options profit calculator with a potential profit and loss profile. Small feature, real workflow value: spreads stop looking like confusing pairs of prints.
Screening and Filtering
Around the live feed sits a set of screening tools: a dedicated options screener, a stock screener, an open interest explorer that tracks chain-level OI changes, sector-level flow views, heatmaps, and flow alerts. The unusual-activity workflow the category is named for, filtering by premium, volume against open interest, expiration, and execution type, runs natively here, and the volume-versus-open-interest logic that drives it is the mechanic covered in open interest vs volume. Saved filters turn a tuned screen into a repeatable feed, with the number of savable filters set by the subscription tier.
The platform publishes its aggregate sentiment math openly: bullish premium is defined as ask-side call premium plus bid-side put premium, bearish premium as the reverse. Having the definition documented matters, because tickers and chains throughout the platform carry bullish and bearish percentages, and a trader should know exactly what those numbers count before leaning on them.
Beyond the Flow: Data Sets Most Competitors Do Not Carry
Three inclusions separate the platform from a bare flow feed. Dark pool data runs as its own live feed alongside the options tape. Periscope, included on every paid tier, tracks SPX market maker exposure and delta flow, the gamma-exposure style positioning data usually sold as a separate product, with update speed tiered by plan: standard on Basic, 10-minute intervals on Pro, 1-minute intervals on Retail Max and Professional. And the congressional trading data set, the feature that first made the brand widely known, tracks disclosed trades by US politicians, with portfolio tracking per member.
The subscription also includes daily downloads of option and dark pool data, historical options and equity feeds, institutional and insider trade data, an economic calendar, earnings views, live charting, news flow, and a community layer built around Discord, chat rooms, and bot commands. A mobile app covers iOS and Android, with the documentation noting the full flow experience is built for desktop and the mobile version is abridged.
Pricing
Four platform tiers, all including the real-time options flow feed and Nasdaq real-time equities data. The pricing page currently displays reduced monthly prices against the standard list prices, shown here exactly as listed.
| Tier | Listed monthly | Current monthly | Billed annually | Key limits and additions |
|---|---|---|---|---|
| Retail Basic | $50 | $38 | $454 | 25 custom alerts, 5 options watchlists (50 contracts each), 5 stock watchlists (50 tickers each), 5 dashboards, 10 saved filters per feed |
| Retail Pro | $75 | $57 | $681 | 100 alerts, unlimited watchlists, dashboards, and saved filters, 10-minute Periscope updates |
| Retail Max | $120 | $92 | $1,102 | Everything in Pro with 1-minute Periscope updates |
| Professional | $200 | $153 | $1,836 | Packaged for advisors and anyone registered with the SEC, FINRA, CFTC, or a securities agency or exchange, with enterprise-grade support |
A free account exists and includes limited flow and options data, enough to see the product but not to trade from it. The pricing page states that every product is a separate subscription: the platform, the API, the Discord bot, and the prediction-market screeners are each their own purchase, with bundles combining them at a discount. API access is explicitly not included in any platform tier, and enterprise API plans start at $750 a month. Annual billing saves up to 15% against monthly. Subscriptions auto-renew by default, and the pricing page states plainly that all sales are final.
For what the feed contains, Retail Basic at $50 list is aggressive pricing, and it undercuts most of the flow category. The honest structural criticism is the separate-subscription model: a trader who wants the platform plus API access is buying 2 products or a bundle, and the pricing page makes that clear only in the fine print under each tier.
Restrictions and Practical Mechanics
Coverage is the hard boundary. The feed covers US options exchanges and US-listed equities, full stop. A trader in Europe or Asia can subscribe and use it for US-listed names, but there is no coverage of local options markets, which is true of the entire flow category and still worth stating.
The tier limits bite in specific places. Retail Basic’s caps of 25 alerts, 5 watchlists per type, and 10 saved filters per feed are workable for a focused trader and constraining for anyone running multiple strategies, which is clearly the point: the unlimited tier costs $25 more at list. The free tier is a preview, not a product, and since flow is only a signal while it is printing, the value of this entire platform lives on the live side of the real-time vs delayed data line. Paying for it and then reviewing prints hours later buys the wrong product.
The labeling mechanics covered above are the other practical caution. Mid fills marked as buys, and buys that may be closing rather than opening, mean the feed’s side emojis are a starting point for the interpretive work described in how to screen for unusual options activity, not a verdict. The documentation says as much, which is to its credit.
Bottom Line
Unusual Whales is the strongest single answer in retail options flow: full-exchange trade capture, execution-level detail per print, documented labeling rules, dark pool and dealer-positioning data included rather than upsold, and a base price below most of the category. It earns the top-tier placement it holds in the best options screeners roundup. The buyer it fits is an options trader who watches the tape during the session and acts on it. The buyer it does not fit is a swing or income trader screening on end-of-day criteria, who would be paying for immediacy that the strategy never uses.
Pros
- Captures every options trade across all US options exchanges, with per-print bid-ask, fill price, size, premium, open interest, volume, and IV
- Documented, rule-based side labeling with published definitions for its bullish and bearish premium math
- Dark pool feed, SPX market maker exposure via Periscope, and congressional trading data included in every paid tier
- Retail Basic at $50 a month list price undercuts most dedicated flow platforms
- Free tier allows seeing the real product before paying
Cons
- US-listed options and equities only, with no coverage of any other options market
- Mid-price fills are currently labeled as buys, so the side markers overstate buying and cannot be traded on alone
- API access is excluded from every platform tier and sold as a separate subscription
- Retail Basic’s 25-alert, 5-watchlist, and 10-saved-filter caps push multi-strategy traders toward the $75 tier
- Subscriptions auto-renew by default and all sales are final, an unforgiving combination for anyone testing the platform on a paid tier
