What is Billy?
Heavy Money compares money share with bet share. System Play contrasts public positioning with money and line movement; Sharp Signal uses public Polymarket wallets scored against closing prices. Analyst agreement, attributed historical trends and modeled true-price comparisons add distinct perspectives.
An Alpha read requires at least three signals on the same pick, not simply the same game. Snapshots refresh about every five minutes. Live signals have not launched, and the API's live tool currently returns an empty live-signal state; desk quotes, fills, positions, order flow and historical records/scorecards are excluded.
