What is this indicator?
Examines days when trading volume has risen compared to the previous day, to gauge the market's crowd behavior. It's usually interpreted alongside NVI and a long-term moving average on top of it.
How to read the chart
A rise happening alongside price movement confirms that move's validity; a divergence between volume and price is often a sign of a weakening trend.
Practical tip
Always check volume alongside price movement; volume on its own, without regard to the price trend, isn't a reliable signal.
