dollar_volume_21d

Mean close x volume over the trailing 21 sessions. A LEVEL, NOT A STATISTIC: price times shares, so its percentile against its own history rises with the price alone - a name that tripled reads 'high liquidity' on unchanged volume. Used across names at one date (tradability), never ranked against its past.
