# MACD Engine

<mark style="color:$info;">The MACD Engine is the core computational logic of the suite, normalizing the MACD values and signal line for all other components (signals, divergences, histogram, etc.).</mark>&#x20;

<mark style="color:$info;">It visualizes the MACD oscillator using a normalized range from -100 to +100 and enables gradient-based color mapping to enhance trend clarity.</mark>

### **MACD Line:** Rendered with dynamic coloring:
