About this app

Watch the market's pulse the way a cardiac monitor watches a patient: a scrolling ECG trace whose beat rate, amplitude and colour are driven by real computed volatility — 20-day realised vol, expansion vs baseline, volume surges, sigma shocks, abnormal sessions and beta vs SPY. Defaults to SPY and QQQ, but any symbol can be admitted to the ward, each with its own BPM and stress score. Includes a 90-day rhythm strip, arrhythmia log of abnormal sessions, diagnostic score breakdown, and one-click watchlist, journal and dashboard publishing.
