Relative Volume (RVOL)
Also called: RVOL
Today's trading volume compared to the stock's normal volume — a 3x RVOL means three times the usual activity, flagging unusual interest.
Relative volume divides current volume by an average (often the 20-day). It's one of the most useful 'something is happening here' signals: institutions and catalysts show up as volume long before they show up in the news.
High RVOL gives moves conviction — a breakout on 4x volume is far more meaningful than the same breakout on average volume. Day traders use RVOL to find the few names actually in play each session.
