The most active hours in this window were 6:00 PM, 3:00 PM, 2:00 PM ET, and the quietest were 9:00 PM and 6:00 AM ET. A wider bar means each interval covers more ground. The takeaway is purely observational: a fixed number of points represents a very different share of typical movement at different hours — in this window, the most active hour covered roughly 1× the ground of the quietest.
These figures shift with volatility regimes — they describe the recorded window above, not a guarantee of the next session.
