Congestion Index for Distinguishing Trends from Ranges

Summary

The Congestion Index is presented as a way to characterize whether a market is trending or moving sideways. Its stated construction compares the market’s percentage change over a selected lookback period with the extreme price range over that period. The intended use is to help traders choose tools suited to the prevailing regime: trend-following indicators can generate repeated false signals in congestion, while oscillators can give premature signals during strong trends.

The document describes the index as directional, with the claimed benefit that it can indicate trend direction without requiring a separate directional indicator. It also claims advantages in recognizing reversals and temporary pullbacks compared with the Vertical Horizontal Filter and Wilder’s ADX. These are assertions attributed to a book description; no formula details, thresholds, chart examples, tests, or performance statistics are included. As a result, the excerpt explains the motivation and claimed characteristics, but is not enough to implement or independently evaluate the indicator.

Key ideas

• The index is intended to distinguish trending conditions from trading ranges.
• Its stated calculation relates percentage price change over a lookback to the period’s extreme range.
• The goal is to help select indicators that fit the current market regime.
• The description claims directional readings and improved reversal and pullback recognition versus two alternatives.
• The excerpt provides no detailed formula, thresholds, or empirical validation.
