Volume,
how much participation sat behind the move?
Volume records how much trading activity occurred during a period. Learn how to compare current activity with a stock’s own history, what unusual volume can mean, why breakout participation matters and why one dramatic spike can still mislead.
Volume tells you how much traded. It does not tell you, by itself, whether the buyers or sellers were “right”.
How to use this library
Volume becomes useful when you compare it.
Ten million shares can be enormous for one company and completely ordinary for another. The number only gains context when you compare it with that security’s normal trading activity, liquidity and the price move happening alongside it.

Start with participation, then connect it to price.
What Is Trading Volume?
What volume records, what it does not record and why context matters more than a raw number.
Relative Volume & Average Volume
How to compare today’s activity with what is normal for the same stock.
Volume Spikes
What unusually high activity can tell you — and why news, rebalancing or one-off prints can distort the story.
Volume & Breakouts
Why expanding participation can add evidence to a break without making the break immune to failure.
Volume Dry-Up
What contracting activity during consolidation can mean — and why “quiet” is not automatically bullish.
The BowerLine rule
Volume is evidence, not a verdict.
A price move on unusually high participation can be more informative than the same move on thin activity. But high volume can accompany buying, selling, panic, news, index changes, capital raisings and failed breakouts. Ask what caused it and what price did with it.
