SquawkFlow and Unusual Whales in detail
Unusual Whales is one of the best-known retail options-flow platforms. Its pricing page lists a "Real-Time Options Flow Feed" described as "Full Tape, 100% market coverage, with unusual activity indicators and custom alerts", a GEX heatmap for all US tickers, downloadable daily options and dark pool data, politician trade information, institutional holders and insider trade data, and Discord community access. Every one of those is a category SquawkFlow does not cover, or covers only as modeled or inferred data.
The two products treat dealer positioning differently, and this is where the table is least flattering to SquawkFlow. Unusual Whales sells Periscope, described in its FAQ as "based on a unique SPX data set, updated every 10 minutes" that "reveals actual Market Maker net positioning and net greek exposure in SPX", drawn from what the same page calls "exchange-verified Market Maker positioning data". Checked October 17, 2026, its pricing page lists SPX Market Maker Exposure with 10-minute updates on both Retail Basic ($50/mo) and Retail Pro ($75/mo), and 1-minute updates on Retail Max ($120/mo); and the free tier sees options flow two trading days late. SquawkFlow has no positioning feed of that kind. Its gamma comes from settled open interest crossed with recent implied volatility from a delayed chain, and the method note on every gamma page states that dealer positioning is an assumption rather than an observable.
The cadence follows from the data source. Unusual Whales publishes an intraday positioning series measured in minutes. SquawkFlow reads a daily settlement file, so the strike-level gamma structure changes once per session and the page refreshes through the day as spot and implied volatility move. Those are different products answering different questions, and the table states both cadences with the page they were read from rather than an ambiguous speed label.
What SquawkFlow does have is open on the web today at no cost and with no account, because signup is paused: SPX dealer gamma, a strike-by-expiration gamma heatmap for SPX, SPY and QQQ, sector rotation, SPX max pain, VIX term structure, an unusual options activity scanner built on delayed chains, an MCP server at mcp.squawkflow.com that needs no key, and embeddable widgets. Its options tape is not full-market and delayed, its dark-pool rows are modeled rather than reported, and it has no mobile app, no community, no custom alerts, and no insider or congressional pages. Its 13F coverage is a nine-manager ledger at /institutions, traceable to SEC accession numbers, not a market-wide database.
Neither platform turns flow into a certainty. Large flow rows can be spreads, hedges, rolls, or closing transactions, and every published gamma figure inherits the same positioning assumption.
