price-volume-coherence-based

Examine synchronization and divergence between price and volume changes, revealing energy alignment or decoupling.

Examine synchronization and divergence between price movement and trading activity:

• volume-confirmed momentum, where directional returns or candle bodies are supported by above-baseline participation;
• weak-volume breakouts or breakdowns as divergence signals, especially when range expands without participation support;
• up-day versus down-day volume asymmetry that reveals whether participation reinforces or contradicts price direction;
• absolute-return and volume decoupling, such as high turnover with muted movement or strong movement on low volume;
• resilience or absorption after negative pressure, combining abnormal volume, close location, and subsequent range behavior.

Seek compact coherence measures that separate aligned price-volume energy from noisy participation or unstable divergence.
