Using the Choppiness Index to Classify Market Regimes

Summary

The Choppiness Index is presented as an oscillator for distinguishing trending conditions, flat markets, and unstable consolidation. Its calculation compares the sum of one-period average true ranges over a lookback window with the high-to-low range across that window, then applies a logarithmic scaling based on the period.

The document gives suggested interpretation boundaries: readings below 38.2 indicate a trend, readings above 61.8 indicate a flat market, and values near 100 indicate unstable consolidation. The indicator exposes configurable settings for the calculation period and the three regime boundaries. These are classification heuristics rather than a tested trading rule; the source provides no performance evidence, asset-specific calibration, or guidance for acting on a regime signal. The material is a translated indicator description and does not establish that the thresholds generalize across markets or timeframes.

Key ideas

• The indicator uses a lookback comparison of summed true range and the full high-low span.
• It classifies conditions as trending, flat, or unstable consolidation.
• The document identifies readings below 38.2 with trends and readings above 61.8 with flat markets.
• Thresholds and period are configurable, and the source offers no validation of their generality.
