Histogram vs Moving Average Convergence Divergence

The histogram in MACD is a bar chart displayed below the price chart that visualizes the distance between the MACD line and signal line, showing whether momentum is accelerating or decelerating in the current trend direction.

Moving Average Convergence Divergence is the full name of the MACD indicator, describing how two exponential moving averages move toward each other, apart from each other, and in opposing directions to signal trend momentum changes.
