MACD Explained: Crossovers, Divergence and Zero-Line Crosses

MACD (Moving Average Convergence Divergence) is a trend-following momentum indicator. It tells you both the direction of the trend and whether it is gaining or losing momentum.

The Three Components

MACD is typically displayed as two lines and a histogram:

MACD Line — the difference between the 12-period EMA and the 26-period EMA.
Signal Line — a 9-period EMA of the MACD line itself.
Histogram — the gap between the MACD line and the Signal line, shown as bars. Growing bars = momentum increasing; shrinking bars = momentum fading.

The Two Main Signals

Where MACD stands right now on each pair
Pair	Signal	MACD
AUD/USD	SELL ★	above signal
EUR/USD	SELL ★★	below signal
GBP/USD	SELL ★	above signal
NZD/USD	SELL ★	above signal
USD/CAD	BUY ★	below signal
USD/CHF	BUY ★★	below signal
USD/INR	BUY ★★	above signal

1. Crossover

When the MACD line crosses above the Signal line, it is a bullish crossover — a potential BUY signal. When it crosses below, it is a bearish crossover — a potential SELL signal.

Crossovers that happen below the zero line are stronger bullish setups (the market is recovering from bearish territory). Crossovers above the zero line in a downtrend are stronger bearish setups.

2. Zero-Line Cross

When the MACD line crosses from negative to positive (crosses zero), the short-term average has overtaken the long-term average — a sign of bullish trend change. The reverse (positive to negative) signals a bearish shift.

How we use it: In our engine, we vote BUY when the MACD line is above the Signal line AND the MACD line is positive (above zero). We vote SELL when the MACD line is below Signal AND negative. This combines both the crossover and the zero-line condition for higher reliability.

MACD Settings We Use

What each reading means to this signal engine
Indicator	Reading	Called	What the engine does with it
MACD	above its signal line	bullish	casts a BUY vote
MACD	below its signal line	bearish	casts a SELL vote

Standard MACD: 12, 26, 9 — this is the universal default and the setting used in our engine on all timeframes and all pairs.

Limitations of MACD

MACD outvoted: the rows where it disagrees with the trend reading
Pair	RSI vote	MACD vote	EMA vote	Tally	Published	Decided by
AUD/USD	no vote	BUY	SELL	1 BUY / 1 SELL	SELL ★	votes tied
EUR/USD	BUY	SELL	SELL	1 BUY / 2 SELL	SELL ★★	majority
GBP/USD	no vote	BUY	SELL	1 BUY / 1 SELL	SELL ★	votes tied
NZD/USD	no vote	BUY	SELL	1 BUY / 1 SELL	SELL ★	votes tied
USD/CAD	no vote	SELL	BUY	1 BUY / 1 SELL	BUY ★	votes tied
USD/CHF	BUY	SELL	BUY	2 BUY / 1 SELL	BUY ★★	majority
USD/INR	SELL	BUY	BUY	2 BUY / 1 SELL	BUY ★★	majority

Lagging indicator. Because MACD is based on moving averages, it is always behind price. By the time MACD crosses, the move may already be partially complete. This is why we combine it with RSI and EMA for earlier confirmation.
Whipsaw in ranging markets. In a sideways market, MACD crosses back and forth frequently, generating false signals. Always check if the pair is trending before acting on a MACD signal.
Signal strength varies by timeframe. A MACD crossover on H1 is much less significant than one on the Daily chart. We show signals on H1, H4, and Daily — weight the Daily more heavily for your own analysis.

MACD Divergence

MACD divergence is one of the most powerful setups in technical analysis. It occurs when price moves in one direction but MACD moves in the opposite direction:

Bullish divergence: Price makes lower lows but MACD makes higher lows — a sign that bearish momentum is weakening.
Bearish divergence: Price makes higher highs but MACD makes lower highs — a sign that bullish momentum is fading.

We do not currently include divergence in the automated signal engine, but it is valuable context when reviewing the H4 and Daily charts.
