The Mass Index was designed to serve as an indicator of upcoming price reversals by quantifying the difference between the high and low prices of a stock over time. The mass index represents an n period sum of a ratio of an exponential moving average of high-low price divided by an exponential moving average of the first average. The input parameters are (1) the period for the first exponential moving average; (2) the period for the EMA of the first average and (3) the summation period for the ratio.
A reversal bulge occurs when a 25-period mass index rises over 27 and then falls below 26.5. Go long when the reversal bulge occurs and 9-period EMA of prices is trending down Go short when the reversal bulge occurs and 9-period EMA of prices is trending up.
