Mass Index
The Mass Index is a range oscillator that uses changes in daily trading price and provides unique market reversal forecasts that other indicators may miss.
Overview
Donald Dorsey's mass index is used to signal an approaching trend reversal. The index is a 25 day moving sum of two moving averages. The first moving average is an exponentially smoothed moving average of the daily close and the second is the first average smoothed a second time. Values over 25 indicate a widening range and those less than 25 indicate a narrowing range.
