Two traders spot the same ascending triangle on ETH/USDT. One profits. The other gets stopped out on a false breakout. Same pattern. Same pair. Different outcomes.
The difference? Volume.
Most traders learn to identify patterns but never learn to read what volume reveals about those patterns. They're reading half the story.
Why Volume Confirms Patterns
Price shows what happened. Volume shows how real it is.
Volume represents conviction. When price moves on high volume, many market participants agree with that direction. When price moves on low volume, few participants are involved making the move suspect.
As Charles Dow put it: "Volume should expand in the direction of the trend."
This relationship forms a simple but powerful matrix:
Price up + Volume up → Bullish, buyers stepping inPrice up + Volume down → Warning, weak convictionPrice down + Volume up → Bearish, sellers in controlPrice down + Volume down → Warning, selling exhausted
Chart patterns are consolidation zones where buyers and sellers battle. Volume tells you who is winning and when one side is about to give up.
The Universal Rule: Contraction and Expansion
Nearly all chart patterns share one volume characteristic: volume decreases as the pattern develops, then surges when price breaks out.
During formation, uncertainty grows. Traders wait on the sidelines. Smart money accumulates or distributes quietly. At breakout, uncertainty resolves sidelined traders enter, stops trigger, momentum traders pile in.
Thomas Bulkowski's research confirms this: breakouts with above-average volume show better follow-through. For crypto specifically, aim for 2–3x the 20-period average to filter out noise.
Volume Signatures by Pattern
Bullish patterns follow a consistent logic:
Ascending triangles, double bottoms, bull flags, and triple bottoms all show declining volume during formationThe second bottom of a double bottom should show lower volume than the first this signals selling exhaustionBreakout volume should expand sharply; pullbacks should happen on diminished volume
Bearish patterns mirror this:
Head and shoulders, descending triangles, rising wedges, and double tops all form on declining volumeThe right shoulder of a head and shoulders forms on noticeably lower volume than the head the classic tellNeckline breakdowns must occur on expanding volume to be valid
Volume Divergence: The Early Warning
Volume divergence when price and volume move in opposite directions often signals a reversal before price confirms it.
Bullish divergence: Price makes lower lows, but volume makes higher lows → selling pressure exhaustingBearish divergence: Price makes higher highs, but volume makes lower highs → buying pressure weakening
This is most powerful when it appears at pattern boundaries, like the second bottom of a double bottom or the second top of a double top.
How to Avoid False Breakouts
False breakouts fool traders every day. Volume filters them out:
Low volume breakout (below 1.5x average) → likely a fakeoutQuick reversal within 1–3 bars → confirms the trapNo follow-through on the second bar → exit or stay out
Always wait for the candle close, not an intrabar spike. Require minimum 1.5–2x average volume before acting.
Putting It Together
Volume isn't a secondary indicator it is the fuel driving price. A technically perfect pattern without volume confirmation fails far more often than one with it. Combine raw volume with On-Balance Volume (OBV) and Accumulation/Distribution for the strongest confirmation signals.
