MACD indicator explained: lines, histogram and crossovers
MACD watches two moving averages – a fast one and a slow one – and measures the gap between them. When the gap grows, the move is speeding up. When it shrinks, the move is slowing down. It sounds complicated, but it is really just “are the averages pulling apart or coming together?”

MACD on the live Bitcoin chart
The live Bitcoin chart with only MACD switched on. The bars under the price are the MACD histogram: green when MACD is above its signal line, coral when it is below.
What is MACD?
MACD stands for Moving Average Convergence Divergence. Convergence means coming together; divergence means moving apart. The indicator tracks exactly that: two exponential moving averages of the price (a 12-day and a 26-day one) and whether they are moving toward or away from each other.
It is made of three parts. The MACD line is the fast average minus the slow average. The signal line is a 9-day average of the MACD line itself – a slower copy that trails behind. The histogram is the bars: the gap between the MACD line and the signal line.
Unlike RSI, MACD has no top or bottom. It is measured in the same units as the price, so Bitcoin’s MACD might be $1,500 while EUR/USD’s is 0.002. That means you cannot compare MACD values between markets – only the shape and direction.
MACD mixes two ideas in one tool: trend (is the fast average above the slow one?) and momentum (is the gap growing or shrinking?). That is why it is so popular – and why it can give mixed messages.
Where it comes from: MACD was created by Gerald Appel, an American money manager and newsletter writer, in the late 1970s. The histogram was added in 1986 by Thomas Aspray, to show crossings earlier. The classic 12, 26 and 9 settings come from Appel.
How MACD is calculated
MACD is built from exponential moving averages (EMAs) – averages that give more weight to recent candles. If you have read our moving averages lesson, you already know the hard part.
- Step 1MACD line = EMA 12 − EMA 26Positive when the fast average is above the slow one.
- Step 2Signal = EMA 9 of the MACD lineA slower, smoother copy of the MACD line.
- Step 3Histogram = MACD − signalThe bars. Above zero when MACD is above its signal line.
| 12-day EMA of the price | 101.50 |
|---|---|
| 26-day EMA of the price | 100.00 |
| MACD line = 101.50 − 100.00 | +1.50 |
| Signal line (9-day EMA of MACD) | +1.20 |
| Histogram = 1.50 − 1.20 | +0.30 |
Here the fast average is above the slow one (MACD positive) and MACD is above its signal line (histogram positive). If tomorrow the histogram drops to +0.10, the gap is shrinking: the upward push is losing speed, even though MACD is still positive.
How to read MACD
The pictures are simple example shapes, so the idea is easy to see. Real charts are messier.
The MACD line crosses above the signal line and later above zero; the bars show the gap between them. Example drawing, not real data. Signal line crossings
When the MACD line crosses above the signal line (histogram turns green), short-term momentum has turned up. Crossing below (histogram turns coral) means it has turned down. These are the most watched MACD events – and also the ones that give the most false alarms in sideways markets.
The zero line
MACD above zero means the 12-day average is above the 26-day average – the short-term trend is up. Below zero means it is down. A crossing of the zero line is slower than a signal crossing but often more meaningful.
Price keeps rising while the MACD bars get shorter: the push is slowing down. Example drawing, not real data. Shrinking bars
When price keeps rising but the histogram bars get shorter, the push is slowing. It does not mean the price will fall – sometimes it just pauses. But it is a sign that the easy part of the move may be over.
Divergence
Like RSI, MACD can disagree with price: a higher price high with a lower MACD high is bearish divergence; a lower price low with a higher MACD low is bullish divergence. On weekly charts these are rare and closely watched.
Common mistakes beginners make
Almost everyone makes these at first. Knowing them saves a lot of frustration.
- Trading every crossingOn a 15-minute chart MACD can cross ten times a day. Most of those are noise. Many traders only pay attention to crossings in the direction of the bigger trend.
- Comparing MACD values between marketsA MACD of 500 on Bitcoin and 2 on Solana says nothing about which one is stronger. The number is in price units. Compare shapes, not sizes.
- Forgetting that it lagsMACD is built from averages of averages. By the time the lines cross, the price has often already moved a good part of the way.
- Ignoring the zero lineAn upward crossing far below zero is a bounce in a downtrend. An upward crossing above zero is a push in an uptrend. They are not the same.
Settings most people use
The numbers in brackets you see on charts – explained in plain words.
- Fast EMA12The quick average. On a daily chart, about two and a half trading weeks.
- Slow EMA26The slow average, about a month of trading days. 12 and 26 are often said to come from the old six-day trading week (two weeks and a month).
- Signal9The average of the MACD line. Some traders use 5 for a faster signal, but 12-26-9 is the standard almost everywhere.
How to use MACD (for beginners)
Six small steps. None of them tells you to buy or sell – they help you read the chart.
- 1Check the zero lineIs MACD above zero (fast average above slow) or below?
- 2Check the barsGreen and growing = the push up is speeding up. Coral and growing = the push down is speeding up.
- 3Watch for shrinking barsBars getting shorter mean the move is losing speed.
- 4Note the crossingsA cross of the signal line is a change in short-term momentum, not a promise.
- 5Zoom outCheck MACD on the daily or weekly chart before trusting a 1-hour signal.
- 6Confirm with priceLook at support and resistance: a crossing next to a big level tells you more.

MACD FAQ
What does MACD stand for?
Moving Average Convergence Divergence. It measures whether a fast and a slow moving average are coming together (converging) or moving apart (diverging).
What do the MACD histogram colours mean?
On Kumocast, green bars mean the MACD line is above its signal line and coral bars mean it is below. Taller bars mean a bigger gap, so a stronger push in that direction.
What are the best MACD settings?
The classic 12, 26 and 9 are by far the most used, which also means most traders are looking at the same lines. Changing them rarely helps beginners.
Is MACD better than RSI?
They answer slightly different questions. RSI shows whether recent moves were stretched on a 0–100 scale. MACD shows whether momentum is speeding up or slowing down and which way the short trend points. Many traders look at both.
Why is MACD negative?
MACD is negative when the 12-day average is below the 26-day average, which happens when prices have been falling recently. It does not mean anything is broken.
Who created MACD?
Gerald Appel developed MACD in the late 1970s. Thomas Aspray added the histogram in 1986.
