Change Angle
The slope of the day-change line over a window — how steeply the move is climbing, in one number.
What it means
Two stocks can both be +6%: one drifted there over three hours, the other did it in four minutes. Change angle measures the slope of the change-percent line over a lookback window, so steepness — the thing your eye reads instantly on a chart — becomes a comparable number.
It behaves like a rate-of-change indicator anchored to the day narrative: high positive angles mark acceleration phases, flattening angles mark stalls before the chart makes them obvious.
Why traders care
- Filters "fresh, accelerating" movers from stale ones at the same day change.
- A falling angle on a rising stock is an early fade warning.
