    Mass Index is an indicator that helps identify trend reversals. It is calculated as the sum of 9-bar Exponential Moving Average (EMA) for daily price changes (high - low) divided by 9-bar EMA applied twice to that range. The indicator provides setup and trigger lines which are used to identify trend reversal: the index line should surpass the setup line and then drop below the trigger line.
