Jurik Moving Average (JMA)

Overview

Jurik Moving Average (JMA) is an adaptive moving average developed by Mark Jurik, widely regarded as one of the most powerful moving averages available to traders. This implementation provides a direct Pine Script translation of the reverse-engineered JMA algorithm

What Makes JMA Special
Unlike traditional moving averages, JMA adapts to market volatility in real-time. This "triple adaptive" approach allows JMA to:

Reduce lag significantly while maintaining exceptional smoothness
React quickly during trending markets
Filter out noise during consolidation phases
Provide clearer trend signals with fewer whipsaws

The Triple Adaptive Edge

JMA employs a three-stage smoothing process:

Preliminary smoothing via an adaptive EMA
Secondary smoothing using a Kalman filter with phase adjustment
Final smoothing through a unique Jurik adaptive filter

Positive values reduce lag but may cause overshoot
Negative values increase smoothness but reduce responsiveness

Power: Smoothing factor (0.1-0.9, default 0.45)

Higher values create smoother curves
Lower values create more responsive but choppy curves

Jurik Moving Average (JMA) is an adaptive moving average developed by Mark Jurik, widely regarded as one of the most powerful moving averages available to traders. This implementation provides a direct Pine Script translation of the reverse-engineered JMA algorithm. Original proprietary algorithm was never published.

Unlike traditional moving averages, JMA adapts to market volatility in real-time. This "triple adaptive" approach allows JMA to:

Reduce lag significantly while maintaining exceptional smoothness
React quickly during trending markets
Filter out noise during consolidation phases
Provide clearer trend signals with fewer whipsaws

JMA employs a three-stage smoothing process:

Preliminary smoothing via an adaptive EMA
Secondary smoothing using a Kalman filter with phase adjustment
Final smoothing through a unique Jurik adaptive filter

This approach combines with a dynamic volatility-based factor (alpha) that adapts to market conditions, making JMA superior to traditional moving averages in most situations.
