Description

Dreiss Choppiness Index is an oscillator developed by an Australian trader E.W. "Bill" Dreiss. It measures the trendiness of a market versus its choppiness and is used to distinguish a trending market from a choppy/rangebound movement.

The Choppiness Index varies from 0 to 100. The standard lookback period is 14 bars with a level of Fibonacci numbers 61.8 or higher being an indication of choppy market and 38.2 or lower marking a trending market. As Dreiss said, "Low readings in the CI correspond closely with the end of strong impulsive movements either up or down, while high readings occur after significant consolidations in the price."

Notice that much like ADX, the oscillator does not recognize between bullish or bearish direction of the trend.
