Volume
How many shares (or coins) changed hands — the fuel gauge behind every price move.
What it means
Volume counts executed quantity. Price says what happened; volume says how much conviction was behind it. A breakout on heavy volume and the same breakout on air are different trades.
Intraday, the useful view is volume per unit of time — per second or per minute — rather than the day total, because it shows acceleration: the moment participation actually arrives.
Why traders care
- Confirms or denies price signals — moves without volume revert more often.
- Sudden volume bursts frequently precede the visible price move by seconds.
