Mass Index

Calcutation:
Mass Index= sum [EMA 9 days on (high-low)/EMA 9 days on (High-low)].

Interpretation:
This indicator can detect trend reversals.
It is based on the difference between high and low. When volatility increases the MASS INDEX increases and when volatility decreases the MASS INDEX decreases too.
To use this indicator it is worth plotting an (9 days) exponential moving average on the price.
A (25- period) Indicator MASS INDEX becomes interesting when it rises above the 27 level. In this case, one should wait until the indicator falls below the 26.5 level.
Then observe the behaviour of the moving average. If the moving average rises, a sell signal is produced.
If the moving average decreases, then it is a buy signal.
