DAS-Style RVOL

DAS RVOL compares the current 1-minute volume to the average volume of that same minute over the past 14 trading days.

Example:

Current 10:00 AM 1-minute volume = 10M

Avg 10:00 AM 1-min volume over last 14 days = 1M

→ RVOL = 10.0 (or 1000%)

So this is time-of-day specific — not just average volume across the whole day.
