Who is moving right now: the price path over the last 1, 5 and 15 minutes, the cumulative session path and the day's shape. A swing is set against a fresh spread, so the symbols fit for scalping stand out from the merely noisy ones.

How the page is built
The scanner covers a liquid universe, not every US listing: the three ETFs and the 300 leaders by today's dollar turnover. The base is the official regular-session open, or the first close of another selected session. On Auto, regular hours replace pre-market after 09:31; before pre-market the latest archived regular session is shown. Path = Σ|Pᵢ − Pᵢ₋₁| / P₀. A minute with no eligible trade is flat, while rates and swings per hour divide by actual elapsed clock time, not by the number of emitted bars. Only completed minute bars enter the cumulative calculations; the current trade is added to the 1 / 5 / 15-minute activity and current net columns.
A swing ends when price reverses by the selected threshold; its unfinished last leg is not counted. Shape appears after 15 clock minutes. Real-time bid-ask and per-second prices are subscribed for the first 100 turnover leaders and the ETFs; the other rows use minute bars and periodic trade snapshots but intentionally show no spread while the stream is connected. A quote that is too old is removed from spread and scalp calculations. The market-event time and the bars/elapsed-minutes cell expose stale or sparse data. Hover a row (tap on touch) for its completed minute closes and zigzag.
