# MACD Histogram

### What is the MACD Histogram?

The MACD Histogram measures the difference between the MACD line and the signal line. It visualizes **momentum shifts** with a clear color-coded bar chart that makes it easy to spot transitions in trend strength.

### Histogram

This version of the histogram uses dynamic color gradients to show trend strength. Positive (above-zero) bars are typically green or teal, and negative (below-zero) bars are red. The color intensity adjusts based on momentum:

Stronger momentum shows in more saturated colors.

Weaker momentum fades into lighter tones.

### Histogram Signals

To help identify turning points more easily, the module can also display **signal markers** as small plus signs (+). These appear when the histogram changes direction:

* A green (+) marks a bullish reversal in the histogram.
* A red (+) marks a bearish reversal in the histogram.

These signals are filtered to appear only at meaningful points, avoiding noise and keeping the chart clean.&#x20;

They're especially useful when momentum turns at extreme levels or when used in combination with MACD Signals or Divergence detection.
