MACD

MACD (Moving Average Convergence Divergence) turns two moving averages into one indicator that reads both the direction and the momentum of a trend.

In one line: MACD (Moving Average Convergence Divergence) turns two moving averages into one indicator that reads both the direction and the momentum of a trend.

What it is

MACD stands for Moving Average Convergence Divergence. It's built from moving averages: the MACD line is the 12-period EMA minus the 26-period EMA, and the signal line is a 9-period EMA of the MACD line. The gap between them is drawn as a histogram. When the two averages converge and diverge, MACD captures shifts in momentum.

How it works

Three readings do the work:

Crossovers: MACD line crossing above the signal line is a bullish momentum cue; crossing below, bearish.
Zero line: MACD above zero means the short-term average is above the long-term one — an uptrend; below zero, a downtrend.
Divergence: if price makes a new high but MACD makes a lower high, upside momentum is fading — an early warning, much like with RSI.

Because it's built from lagging averages, MACD confirms rather than predicts, and it whipsaws in sideways markets.

Worked example

Example

A large-cap has been basing sideways. Its MACD line, sitting just below zero, curls up and crosses above the signal line while the histogram flips from negative to positive — momentum is turning up. Shortly after, the MACD line pushes above the zero line, confirming the short-term trend has overtaken the long-term one. A trader uses this as confirmation for a long already supported by price breaking resistance, not as a lone trigger.

Why it matters

MACD is popular because it folds trend and momentum into one clean visual, smoothing the noise of raw price. Its weakness is lag and false signals in choppy markets — crossovers fire late and flip-flop when there's no trend. Best used to confirm a thesis from price and trend, not to generate trades in isolation.

Common questions

FAQ

Is MACD a leading or lagging indicator?

Lagging. Because it's built from moving averages of past prices, MACD confirms momentum shifts after they begin rather than predicting them. Divergence is its most forward-looking use, but even that is a warning, not a forecast.

What are the standard MACD settings?

The classic settings are 12, 26, and 9 — a 12- and 26-period EMA for the MACD line and a 9-period EMA for the signal line. They're a fine default; changing them mainly trades sensitivity for smoothness. Consistency matters more than the exact numbers.
