Volume Unusualness
How unusual the ticker’s volume is today vs its own trailing ~90 trading days, as a percentile (0-100) and decile (1-10) for both regular-session stock volume and total (call + put) option volume. This is outlier-robust and comparable across names, unlike a raw volume-vs-average ratio. A metric is null when fewer than 30 trailing days of history are available. Defaults to the last market day.

Volume Unusualness Response
How unusual a ticker's volume is today, standardised against its own trailing ~90 trading days.
Each metric is expressed as a percentile (0-100) and a decile (1-10) — outlier-robust and comparable
across names, unlike a raw volume-vs-average ratio. stock covers regular-session share volume;
option covers total (call + put) option volume. samples is the number of trailing days used
(a metric is null when fewer than 30 days of history are available).
