Composite Momentum Index

The Composite Momentum Index indicator is a technical oscillator designed to capture market momentum by aggregating multiple timeframes of volatility-adjusted Chande Momentum values into a single, cohesive reading. It helps traders identify potential trend reversals, overbought or oversold conditions, and momentum shifts through a smoothed composite signal.

Usage

The Composite Momentum Index is primarily used to identify market extremes and trend strength. Traders can interpret the indicator using several methods:

• Overbought/Oversold (OB/OS) Levels: The oscillator includes horizontal levels at ±30 and ±70. Values exceeding ±70 typically indicate extreme momentum conditions where a reversal might be imminent.
• Signal Line Crossovers: The indicator features a smoothed index line and a trigger line. A crossover where the index moves above the trigger (indicated by a green ribbon) suggests bullish momentum, while a move below (red ribbon) suggests bearish momentum.
• Divergences: By comparing price action to the peaks and troughs of the index, traders can look for bullish or bearish divergences to anticipate potential trend exhaustion.
• Zero-Line Crosses: Movement around the zero line helps determine the overall bias of the momentum.

Details

The script is a derivative of Chande's Dynamic Momentum Index (DMI), but instead of using a single timeframe, it calculates modified 5, 10, and 20-period values. Each component is calculated using a Double Exponential Moving Average (DEMA) to reduce lag.

A unique feature of this composite version is that it weights each timeframe based on its respective standard deviation (volatility). This ensures that timeframes experiencing higher relative volatility have a greater impact on the final index value, providing a more responsive and context-aware momentum reading compared to traditional static oscillators.

Settings

• Source: Determines the price data used for the momentum calculations (default is Close).
• Composite Smoothing Length: Sets the length of the EMA used to smooth the final composite index.
• Signal Length: Defines the length of the Simple Moving Average (SMA) used to create the trigger/signal line.

FAQ

What are the main levels to watch on the Composite Momentum Index?

The key levels are 70 and -70 for extreme momentum conditions, and 30 and -30 for initial overbought/oversold thresholds.

How does volatility affect the script?

The script uses standard deviation to weight the different momentum periods. Higher volatility in a specific timeframe increases its influence on the total composite score.
