Unusual Whales is a leading options-flow analytics platform. astrostock pairs the same families of institutional data — dark pool prints, unusual options flow, dealer gamma — with a full technical-analysis workspace, so the flow you read and the chart you trade live in one place.
Options-market analytics in depth: exchange-wide flow aggregation, Greek-exposure dashboards, political-trade tracking, heatmaps, and a research feed built around what institutions are doing in the options market.
A complete charting workspace around the flow: 153 indicators, 132+ drawing tools, saved layouts, a 34-recipe scanner, alerts, and specialist Gann, astrology, cycle and statistical suites — plus AI that analyzes the chart you actually configured.
