Dual-Scale MACD

Dual-Scale MACD is a dual-timeframe momentum indicator that displays a scaled short-term MACD together with a long-term MACD in the same pane.

The short-term MACD can be amplified by a configurable scale ratio, allowing its momentum structure to be visually aligned with the long-term MACD.
All EMA parameters are fully configurable, making this indicator suitable for experimentation with multi-cycle momentum resonance.

Features

Two independent MACD systems (short-term + long-term)

Fully configurable EMA parameters

Adjustable scale ratio for visual alignment

Clean histogram + top-layer signal line

Use cases

Multi-cycle momentum comparison

Trend confirmation & divergence analysis

Studying MACD resonance across time scales

This indicator is intended for analytical and educational purposes.
