MACD indicator
Also called: MACD, Moving Average Convergence Divergence, MACD histogram, Signal line, MACD indikatörü, MACD göstergesi
A trend and momentum indicator built from the gap between two exponential moving averages; standard settings are 12, 26 and 9, and it lags price.

What does MACD measure?
MACD is the 12-period exponential moving average minus the 26-period exponential moving average. The result is the MACD line. When the fast average is above the slow one, MACD is above zero; when it is below, MACD is below zero.
The second line is the signal line, a 9-period exponential average of the MACD line. The third part is the histogram, which draws the gap between the MACD line and the signal line as bars. All three come from the same source: candle closes.
MACD tells you two things at once. Whether it sits above or below zero shows which side of the slow average the fast one is on, roughly the trend's direction. The histogram growing or shrinking shows that gap opening or closing, meaning the move is speeding up or slowing down.
Because everything is built from averages, MACD walks behind price. Price turns first, MACD later. That lag is not a flaw, it is how the indicator works, and using it well means accounting for it.
How to read MACD on a chart
Say EUR/USD is in a downtrend. Price fell from 1.0920 to 1.0820, the MACD line is at −0.0018 and the signal line at −0.0012. MACD is below both zero and the signal: the fast average is 18 pips under the slow one and the gap is widening.
Then price corrects up to 1.0865. The histogram shrinks and MACD crosses above the signal line, a bullish crossover. But MACD is still below zero. The decline has slowed; the averages have not changed direction. That is a breather inside the trend, not a reversal.
The real information comes from price. If the correction stalls at 1.0865, in a supply zone where sellers pushed before, and price turns down and closes below the last candle's low, the structure is still making lower highs. MACD crossing back under its signal confirms this later, often a few candles late.
The stop goes to structure again. If you consider selling, it belongs a little above the correction's high at 1.0865. Entry 1.0845, stop 1.0870 gives 25 pips of risk; that is 1R. The MACD reading doesn't change that distance.
Try it on a chart
This chart has no MACD line, only candles and a marked zone. What MACD measures is how far the short-term average has pulled away from the long-term one; you can read that from the order of highs and lows and the size of recent candles. Look at the trend's structure first, then at where price sits relative to the zone.
The downtrend structure holds; price corrected higher and turned back from the supply zone. What do you do?
No sign-up needed. Take a guess; when the chart opens, you'll see why.
The most common MACD mistake
Treating every crossover as a buy or sell signal. In a sideways market MACD and its signal line cross constantly. Someone trading each cross gets thrown back and forth inside the range and is late every time.
Reading a crossover below zero as a reversal. In a downtrend, MACD crossing above its signal usually just marks the start of a correction. If the trend holds, that correction tends to end at resistance or in a supply zone.
Forgetting the lag. By the time the cross arrives, part of the move has happened. Waiting for the cross and then a candle close means chasing price from far away; when you place the stop on structure, the distance grows and you have to trade smaller.
When does MACD fail?
In ranges. When price chops in a tight band the two averages stick together, MACD wobbles around zero and crossovers lose meaning. The range edges tell you far more than MACD does.
In sudden moves. When a news candle moves price 60 pips at once, MACD only shows it over the following candles. Sharp reversals are the same: price has turned while MACD still points the old way.
When comparing markets. MACD is measured in price units. A value of 0.0015 on EUR/USD might be 4 dollars on gold. A fixed rule like buy above a certain number won't fit every chart; compare a chart with its own history instead.
Frequently asked questions
Why are the MACD settings 12, 26, 9?
They are the settings used by Gerald Appel, who developed the indicator, and they became the standard over time. Nearly every platform uses them by default. Shorter settings make MACD faster but noisier; longer ones make it slower but calmer. Changing the settings doesn't remove the lag, it only shifts the balance between lag and false signals.
What does the MACD histogram show?
The histogram is the difference between the MACD line and the signal line. Growing bars mean MACD is pulling away from its signal, so the move is accelerating. Shrinking bars mean it is slowing. The histogram crossing zero is the same moment as the MACD and signal lines crossing. A shrinking histogram isn't a reversal; it usually marks a pause or a correction.
Is MACD better than RSI?
They answer different questions. MACD measures the gap between two averages, focuses on trend direction and speed, and has no upper limit. RSI moves between 0 and 100 and measures how one-sided recent moves have been. Both come from closing prices, so using both on one chart often shows the same thing twice. Whichever you use, the decision still comes from structure and the stop.
