Core logic

The Mass Index evaluates changes in price range by comparing two exponential moving averages of the high–low range and summing their ratio over a defined period.

Key principles:

* the high–low range reflects daily price expansion
* a single EMA smooths short-term range fluctuations
* a double EMA further normalizes range behavior
* the ratio between both EMAs highlights volatility shifts
* summing the ratio emphasizes sustained expansion phases

When the Mass Index rises above a predefined trigger level, it signals increased volatility often associated with potential trend reversals. The indicator does not indicate direction and should be combined with other tools for bias confirmation.

Visualization

The script plots:

* the Mass Index line in a separate indicator pane
* a dashed trigger level highlighting reversal-risk zones
* an additional reference level marking potential setup areas
* clean line rendering for clear volatility assessment

This visualization helps identify periods of abnormal range expansion at a glance.

Use case

This indicator is intended for:

* identifying potential trend reversal zones
* detecting volatility expansion phases
* filtering late trend entries during unstable conditions
* supporting reversal and mean-reversion strategies
* complementing directional indicators with volatility insight

It is most effective when combined with trend direction tools, momentum indicators, or AI-assisted chart analysis.
