Using the Choppiness Index to Distinguish Trends from Ranges

Summary

The document explains the Choppiness Index as a bounded indicator for judging whether price action is trending or moving sideways. It describes the reading inversely to price direction: higher values suggest a greater likelihood of a range, while lower values suggest a trend. It gives thresholds of 38.2 and 61.2 as reference points, and presents a formula using summed average true range relative to the high-low range over a lookback period of 14.

The indicator is presented as a market-regime filter, not a standalone entry or exit system. The document supplies an equation but no examples, backtest, market, timeframe, or evidence that the stated thresholds work consistently. Readings near either boundary may not provide a clear classification, and the explanation does not discuss smoothing or how to combine the measure with other signals. Its remaining text concerns website privacy and does not add trading guidance.
