MACD Indicator Explained: A Practical Guide

MACD, short for Moving Average Convergence Divergence, is built from two exponential moving averages: a faster one and a slower one. The MACD line is the difference between them, and a signal line (a moving average of the MACD line itself) is plotted alongside it to help spot turning points.

The histogram is the gap between the MACD line and the signal line, plotted as bars. Growing bars mean the gap is widening (momentum accelerating in the current direction), shrinking bars mean it is narrowing (momentum fading), often before a crossover actually happens.

The most commonly watched signal is a crossover: when the MACD line crosses above the signal line, it is read as bullish momentum building, and the reverse is read as bearish. Crossovers happen often though, especially in choppy, sideways markets, and treating every single one as a trade signal is a common way new traders overtrade.

MACD is a lagging indicator by construction, since it is built from moving averages, so it confirms a shift more often than it predicts one.
