Why is volume important in trading?
Quick Answer
Volume confirms price movements - high volume validates breakouts and trends, while low volume suggests weak moves that may fail.
Detailed Explanation
Volume represents the number of shares or contracts traded in a period. It's crucial because it validates price action. Strong moves on high volume are more likely to continue than moves on low volume. Breakouts should occur on above-average volume to be considered valid. Volume divergences (price rising on declining volume) often precede reversals.

Example
Stock breaks above $100 resistance on 3x average volume = strong breakout. Same break on 0.5x volume = suspect, likely to fail.
