Response

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).
