MACD 4C Pro

MACD 4C Pro — 4-Color MACD Histogram with Momentum Phase Detection

MACD 4C Pro is a refined 4-color MACD histogram for Indie that clearly visualizes momentum phase shifts using a deterministic and noise-controlled logic model.

Unlike the standard MACD that typically shows a line and a signal crossover, this version displays the MACD line itself as a color-coded histogram, allowing traders to instantly see:

• Whether momentum is positive or negative
• Whether momentum is strengthening or weakening
• When the market transitions through the zero line

This makes it especially effective as a trend confirmation and momentum state filter.

What Makes This Version Different

Many traders are confused when MACD histograms differ between platforms.
This indicator removes that ambiguity:

• It uses the true MACD line, not (MACD − Signal).
• Colors represent both polarity and slope.
• Zero-line crossovers are clearly marked.
• A symmetric noise filter prevents false micro color flips.

The logic is deterministic and NaN-safe, meaning no random first-bar artifacts or inconsistent slope comparisons.

4-Color Momentum Logic

Each bar reflects both direction and acceleration:

• Lime → Positive and rising (bullish momentum strengthening)
• Green → Positive but falling (bullish momentum weakening)
• Maroon → Negative and falling (bearish momentum strengthening)
• Red → Negative but rising (bearish momentum weakening)

This transforms MACD into a clear momentum phase visualization tool rather than a simple crossover oscillator.

Key Features

• 4-state color logic (polarity + slope)
• Zero line reference
• Optional Signal Line
• Optional Zero-Cross markers (U/D labels)
• Symmetric Noise Filter (abs MACD threshold)
• Clean deterministic behavior
• Indie-native implementation using Macd.new

Parameters

• Fast EMA (default 12)
• Slow EMA (default 26)
• Signal Length (default 9)
• Noise Filter (abs MACD) — filters small fluctuations
• Toggle: Show Signal Line
• Toggle: Show Zero Cross Markers

Best Use Cases

• Trend-following systems
• Breakout confirmation
• Higher-timeframe momentum bias
• Exit timing refinement
• Psychological momentum phase reading

Works on all timeframes.
Lower timeframes may benefit from a small noise threshold.

Who This Is For

• Traders who prefer histogram-style MACD
• Momentum traders
• Price action traders using phase confirmation
• System builders needing a clean momentum state visualizer

This is not a predictive or zero-lag MACD.
It is a clean momentum state indicator designed for clarity and structural consistency.
