Mass Index

Sums the ratio of a single- to a double-smoothed high-low range over 25 bars, so widening ranges inflate the reading regardless of direction. Donald Dorsey’s "reversal bulge" — a rise above 27 followed by a drop below 26.5 — flags a likely trend change, while the direction of the new trend must be read from a companion indicator.
