What It Is
Volume divergence occurs when price and volume move in opposite directions. It's a warning signal that the current price trend lacks the participation needed to sustain itself and may be approaching a reversal or significant pullback.
Key insight: In healthy trends, price and volume move together. When they diverge, something is wrong beneath the surface. The market is moving on less and less conviction, even as price continues in its trend direction. This is unsustainable.
Volume divergence is particularly powerful because it reveals institutional behavior. When institutions stop participating in a rally (volume declines), retail traders are often the last ones buying — and they're about to become exit liquidity.
Trading Volume Divergence
Price makes a new high but volume on the push is lower than the previous high. Each new high has less fuel behind it. Don't immediately short — tighten stops on longs and watch for a structural break.
Price makes a new low but volume is declining. Sellers are exhausting themselves. Watch for a reversal candle with a volume spike — that's the signal that buyers have arrived.
When price makes a new high on declining volume AND RSI/MACD show bearish divergence, you have triple confirmation. This confluence significantly increases the probability of a reversal.
Apply this concept in combination with others. No single concept tells the whole story - confluence is key.
