low_volume_regime

In a sustained quiet stretch — the last 30 minutes traded at or below 30% of this name's usual volume for this time of day.

definition
sum(volume, trailing 30 min) / expected_30min <= 0.30 to turn on; stays on until > 0.60. expected_30min = this bucket's median 15-min volume + the previous bucket's, medians over the last 20 sessions (volume_profile). Regular hours only; null until the name has a profile.

Same grammar on scan and webhooks. This signal lives in intraday state: ?asof= reads carry it at interval=1h with a timestamp, not at daily resolution.
