ProBors vs Quiver: sample research day
Question: "What are politicians buying in energy tickers this month, and are whales aligned?"
On Quiver: jump between congress module and other screens; export or screenshot; chart elsewhere.
On ProBors: congress filter → whale filter on same tickers → AI table combining both → chart from Polygon inside the stack.
