Crossover vs Moving Average Convergence Divergence

A crossover occurs when one technical line passes through another on a chart — such as the MACD line crossing the signal line or two moving averages crossing — generating a buy or sell signal based on the direction of the cross.

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.
