Volume Indicators Explained
Understand how volume indicators help confirm price moves, spot unusual participation, and add context to breakouts or reversals.
Common Formula
Volume indicators compare current traded shares or contracts against prior activity, averages, or price direction
What volume indicators measure
Volume indicators study participation. They can show whether a price move happened with expanding activity, normal activity, or weak participation that deserves more caution.
How traders read them
Rising price with above-average volume can suggest stronger demand, while falling price with heavy volume can show aggressive selling. Low-volume moves can still matter, but they are easier to question without confirmation.
Why context matters
Volume should be compared with the instrument's normal liquidity, market session, news cycle, and broader trend. A volume spike near earnings, ETF rebalance dates, or major macro news may carry a different meaning than ordinary trading.
