signal.confluence

10 crread-only

The moat join — where do informed INSIDERS (Form 4 open-market buys), institutional SMART MONEY (13F cluster-buys), and CONGRESS (US House STOCK Act trades) AGREE? Pass a `ticker` for all three legs on one name (insider + fund + congress net buy/sell + a verdict that escalates to triple_confluence_buy when all three are buying). Omit `ticker` for the market-wide ranked list — insider×fund names, surfaced first when Congress is buying too (triple_confluence). Joined on ticker — never a fuzzy name match. Each leg carries source provenance; congress $ are amount-range midpoints (approximate).

Parameters#
