What is 3 Color MACD?
3 Color MACD displays a MACD histogram with three color states, a signal line, and a zero-level reference in a separate MT4 pane. The colors make changes in histogram state easier to compare across the selected history.
The package includes an .ex4 file. The indicator keeps the familiar MACD components together while adding a color-coded presentation for chart review.
How to use 3 Color MACD
Compare histogram color, bar height, signal-line position, and the zero level with the main price chart. The combined view helps organize several MACD references without switching panes.
FastEMA, SlowEMA, SignalSMA, CountBars, Line, and Zero_level control the display. The defaults shown in the Inputs image are 12, 26, 9, 300, 3, and 0.0.
Where it helps
Histogram, signal line, and zero level share one pane.
Color changes make the histogram easier to scan.
Fast, slow, signal, history, and line inputs are exposed.
