Volatility outlier

A bar far larger than this instrument usually prints at this hour. The hour is the whole point: the same range is unremarkable at the London open and extraordinary at 03:00.

What it looks like on a chart

A mark under the bar. No level.

Settings, as they are actually applied on each timeframe. A dash means this scanner emits no settings string. Where a number differs by timeframe, that is a span of chart time resolved into bars.
Timeframe	Bars of history it reads	Settings	Events, last 30 days
M15	2880	median 15-minute range per UTC hour, built from the last 30 days; threshold 4x	436
M30	2880	median 15-minute range per UTC hour, built from the last 30 days; threshold 4x	215
H1	2880	median 15-minute range per UTC hour, built from the last 30 days; threshold 4x	63
H4	2880	median 15-minute range per UTC hour, built from the last 30 days; threshold 4x	11

Not on D1. It keys its baseline on the UTC hour, which needs more than one bar per hour to mean anything.
