The Mass Index indicator is designed to identify potential trend reversals by measuring the changes in the average range between the highest and lowest prices over a specified period, typically 25 periods. When the price range widens, the Mass Index increases, and when the range narrows, it decreases.Also recommended: institutional fractal dimension index (regime detector) - similar indicator with strong performance on MetaTrader 5.
A common application involves using a 9-period setting to signal potential buy or sell opportunities. The indicator aims to predict trend reversals; therefore, a long position might be considered if the moving average indicates a downtrend, and a short position if it indicates an uptrend.
The indicator utilizes various smoothing algorithms, including:
- Simple Moving Average
- Exponential Moving Average
- Smoothed Moving Average
- Linear Weighted Moving Average
- JMA Adaptive Average
- Ultralinear Smoothing
- Parabolic Smoothing
- Tillson's Multiple Exponential Smoothing
- Smoothing with Tushar Chande's Algorithm
- Smoothing with Perry Kaufman's Algorithm
It is important to note that the phase type parameters for different smoothing algorithms can have distinct meanings. For JMA, it's an external phase variable ranging from -100 to +100. For T3, it's a smoothing ratio multiplied by 100 for visualization. For VIDYA, it's a CMO oscillator period, and for AMA, it's the slow EMA period. In other algorithms, these parameters may not influence smoothing. For AMA, the fast EMA period is fixed at 2 by default, and the exponent ratio is also 2.
The indicator relies on classes from the smoothalgorithms.mqh library, which must be placed in the terminal_data_folder\mql5\include directory. The usage of these classes is detailed in the associated article.
