Market Synopsis
The Mass Index uses the range of the bars to calculate several values, including exponential averages of the ranges. It then calculates and plots an index of these calculations. The Mass Index is used in trending markets to monitor direction and warn of potential changes in market direction.
The Mass Index indicates a possible price reversal when the Mass Index line crosses above the setup line and subsequently falls below the trigger line. This is known as a reversal bulge. The Mass Index does not identify the trend direction, but rather warns of possible reversals.
