Volume & Short Interest
Where today's volume is running far above normal (an unusualness ratio above 1 means heavier-than-usual trading) and which names carry the highest short interest, a setup for potential squeezes.
Options Flow
Where the options market is busiest, and where volume is unusually high versus open interest (the Vol/OI ratio) — a common positioning signal ahead of catalysts.
Insider Activity
Open-market buying and selling by company insiders. Cluster buying is often read as a confidence signal; switch the window to compare the last day, week, or month.
