MACD divergence occurs when price moves in one direction while the Moving Average Convergence Divergence (MACD) indicator moves in another, showing that momentum is no longer confirming the latest price move. Bullish MACD divergence occurs when price makes a lower low while MACD makes a higher low, while bearish MACD divergence occurs when price makes a higher high but MACD makes a lower high.<\/strong><\/p>\n\n\n\n

MACD divergence can provide an early indication that momentum is weakening, but it does not guarantee a reversal. Traders can analyse divergence using either the MACD line or MACD histogram and then look to price action or market structure for additional confirmation.<\/p>\n\n\n\n

<\/div>\n\n\n\n

What Is MACD Divergence?<\/strong><\/h2>\n\n\n\n

MACD divergence is a disagreement between the direction of price and the direction of the MACD indicator.<\/p>\n\n\n\n

In a strong directional move, price and momentum will often move broadly together. Higher price highs may be accompanied by higher MACD highs, while new price lows can occur alongside lower MACD readings.<\/p>\n\n\n\n

Divergence appears when this relationship changes.<\/p>\n\n\n\n

For example, price might make a new high while MACD produces a lower high. Price has continued upwards, but momentum measured by MACD has not confirmed the latest high.<\/p>\n\n\n\n

The opposite can occur during a decline. Price reaches a new low while MACD forms a higher low, indicating that bearish momentum has weakened relative to the previous price low.<\/p>\n\n\n\n

CME Group<\/a> identifies divergence as one of the main signals traders analyse with oscillators and notes that MACD moving in a different direction from price can indicate a possible change in trend.<\/p>\n\n\n\n

The important word is possible<\/strong>. Divergence measures changing momentum rather than predicting with certainty where price will move next.<\/p>\n\n\n\n

<\/div>\n\n\n\n

How Does MACD Work?<\/strong><\/h2>\n\n\n\n

MACD, or Moving Average Convergence Divergence, is a momentum indicator built from exponential moving averages.<\/p>\n\n\n\n

The standard MACD calculation uses:<\/p>\n\n\n\n

MACD line = 12-period EMA – 26-period EMA<\/strong><\/p>\n\n\n\n

A 9-period exponential moving average of the MACD line is then used to create the signal line<\/strong>.<\/p>\n\n\n\n

Standard MACD therefore consists of:<\/p>\n\n\n\n

MACD line:<\/strong> The difference between the shorter and longer EMA.<\/p>\n\n\n\n

Signal line:<\/strong> A smoothed EMA of the MACD line.<\/p>\n\n\n\n

MACD histogram:<\/strong> The difference between the MACD line and signal line.<\/p>\n\n\n\n

When the shorter EMA moves further above the longer EMA, MACD rises. When the shorter EMA moves further below the longer EMA, MACD falls.<\/p>\n\n\n\n

This means MACD divergence is ultimately showing that the relationship between short and longer-term momentum is changing even though price has continued moving in its existing direction.<\/p>\n\n\n\n

<\/div>\n\n\n\n

MACD Histogram Explained<\/strong><\/h2>\n\n\n\n

The MACD histogram visually represents the difference between the MACD line and the signal line<\/strong>, making it easier to see whether momentum between the two is expanding or contracting.<\/p>\n\n\n\n

The calculation is:<\/p>\n\n\n\n

MACD Histogram = MACD Line – Signal Line<\/strong><\/p>\n\n\n\n

If the MACD line is above the signal line, the histogram is positive and appears above zero.<\/p>\n\n\n\n

If the MACD line is below the signal line, the histogram is negative and appears below zero.<\/p>\n\n\n\n

Charles Schwab<\/a> explains that MACD is commonly interpreted in relation to its signal line, with the distance between the two reflecting changes in momentum. The MACD histogram visualises that relationship by showing the difference between the MACD line and signal line. <\/p>\n\n\n\n

The size and direction of the histogram bars are therefore important.<\/p>\n\n\n\n

Growing positive bars<\/strong> show the MACD line moving further above the signal line.<\/p>\n\n\n\n

Shrinking positive bars<\/strong> show the MACD and signal lines moving closer together.<\/p>\n\n\n\n

Growing negative bars<\/strong> show the MACD line moving further below the signal line.<\/p>\n\n\n\n

Shrinking negative bars<\/strong> show the MACD and signal lines converging.<\/p>\n\n\n\n

A shrinking histogram can therefore show that momentum is changing before the MACD and signal lines actually cross.<\/p>\n\n\n\n

However, a shrinking histogram is not automatically a reversal signal. The lines can begin separating again and the existing trend can continue.<\/p>\n\n\n\n

<\/div>\n\n\n\n

What Is MACD Histogram Divergence?<\/strong><\/h2>\n\n\n\n

MACD histogram divergence occurs when price makes a new high or low but the corresponding peak or trough in the MACD histogram moves in the opposite direction.<\/p>\n\n\n\n

For example:<\/p>\n\n\n\n

Price:<\/strong> higher high
MACD histogram:<\/strong> lower positive peak<\/p>\n\n\n\n

This is bearish MACD histogram divergence.<\/p>\n\n\n\n

Alternatively:<\/p>\n\n\n\n

Price:<\/strong> lower low
MACD histogram:<\/strong> higher negative trough<\/p>\n\n\n\n

This is bullish MACD histogram divergence.<\/p>\n\n\n\n

Histogram divergence is slightly different from comparing price directly with the MACD line.<\/p>\n\n\n\n

The MACD line represents the difference between two exponential moving averages. The histogram represents the difference between the MACD line and its signal line.<\/p>\n\n\n\n

Histogram divergence therefore focuses specifically on changes in the momentum of MACD itself<\/strong>.<\/p>\n\n\n\n

This can make the histogram particularly useful for visualising when momentum is contracting even though price is still moving in its original direction.<\/p>\n\n\n\n

Quantifying Bullish MACD Histogram Divergence<\/strong><\/h2>\n\n\n\n

Bullish MACD histogram divergence can be quantified by comparing two corresponding price lows with the MACD histogram values recorded around those lows.<\/p>\n\n\n\n

The basic condition is:<\/p>\n\n\n\n

Price Low 2 < Price Low 1<\/strong><\/p>\n\n\n\n

while:<\/p>\n\n\n\n

MACD Histogram Low 2 > MACD Histogram Low 1<\/strong><\/p>\n\n\n\n

Price has therefore fallen further, but the MACD histogram has become less negative.<\/p>\n\n\n\n

For example:<\/p>\n\n\n\n

Measurement<\/strong><\/td>First low<\/strong><\/td>Second low<\/strong><\/td><\/tr>
Price<\/td>$100<\/td>$95<\/td><\/tr>
MACD histogram<\/td>-2.0<\/td>-1.2<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Price has declined by another 5%, producing a lower low.<\/p>\n\n\n\n

The MACD histogram has moved from -2.0 to -1.2<\/strong>, creating a higher low.<\/p>\n\n\n\n

This can be quantified in several ways.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Absolute histogram difference<\/strong><\/h3>\n\n\n\n

The simplest measurement is:<\/p>\n\n\n\n

Histogram divergence = Histogram Low 2 – Histogram Low 1<\/strong><\/p>\n\n\n\n

Using the example:<\/p>\n\n\n\n

-1.2 – (-2.0) = +0.8<\/strong><\/p>\n\n\n\n

The histogram has improved by 0.8 units while price has made a lower low.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Percentage change in histogram magnitude<\/strong><\/h3>\n\n\n\n

The contraction in negative histogram magnitude can also be expressed as a percentage:<\/p>\n\n\n\n

(|First Histogram Low| – |Second Histogram Low|) \/ |First Histogram Low| \u00d7 100<\/strong><\/p>\n\n\n\n

Using the example:<\/p>\n\n\n\n

(2.0 – 1.2) \/ 2.0 \u00d7 100 = 40%<\/strong><\/p>\n\n\n\n

The magnitude of the negative histogram has therefore contracted by 40%.<\/p>\n\n\n\n

That provides a numerical description of the divergence, but it does not mean that a 40% contraction has a fixed probability of producing a reversal<\/strong>.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Price change alongside histogram change<\/strong><\/h3>\n\n\n\n

A trader or analyst can also record both variables:<\/p>\n\n\n\n

Price:<\/strong> -5%
Histogram magnitude:<\/strong> -40%<\/p>\n\n\n\n

This shows that price has continued lower while bearish MACD histogram momentum has contracted substantially.<\/p>\n\n\n\n

Quantifying the relationship can be useful when backtesting because it replaces a subjective observation such as \u201cthe second histogram trough looks higher\u201d with predefined rules.<\/p>\n\n\n\n

For example, a test could require:<\/p>\n\n\n\n
