Choppiness Index


The Choppiness Index is a technical analysis tool developed by Australian commodity trader Bill Dreiss to help traders determine whether a market is trending or ranging. The index measures the volatility of price movements, which can be a helpful indicator for traders and investors to assess the strength and direction of market trends. This article will explain the calculation of the Choppiness Index, its interpretation, and its applications in trading.

Choppiness Index

Calculation of the Index

The Choppiness Index is calculated using the Average True Range (ATR) and the natural logarithm (ln) of price movements over a specific period, usually 14 days. The formula for the index is:

Choppiness Index = 100 * ln (Sum of ATR over n periods / (Highest Price – Lowest Price)) / ln(n)


  • ATR is the Average True Range
  • n is the number of periods (typically 14)

The Choppiness Index ranges between 0 and 100, with lower values indicating a trending market and higher values suggesting a ranging market.

Interpreting the Index

Trending Markets

When the Choppiness Index value is low (usually below 38.2), it suggests the market is experiencing strong directional movement, which could be either upward or downward. This is considered a trending market, where traders can potentially benefit from taking positions in the direction of the trend.

Ranging Markets

When the Choppiness Index value is high (usually above 61.8), it suggests that the market is experiencing a period of consolidation or sideways price movement. This is considered a ranging market, where traders may find it more challenging to identify clear entry and exit points based on price movements alone.

Applications in Trading

Identifying Trade Setups

The Choppiness Index can help traders identify potential trade setups by providing insights into the current market environment. For instance, in a trending market, traders can look for opportunities to enter trades in the direction of the trend, using other technical indicators or price action analysis to refine entry points. In a ranging market, traders might focus on range-bound strategies, such as buying near support levels and selling near resistance levels.

Limitations of the Index

While the Choppiness Index can provide helpful information about market conditions, it’s essential to recognize its limitations. The index does not provide information about the direction of the trend, only its strength.

Additionally, the Choppiness Index is based on historical price data and may not accurately predict future market behavior. It’s essential for traders to use the Choppiness Index in conjunction with other technical analysis tools and fundamental analysis to gain a comprehensive understanding of market conditions and potential trading opportunities.

The Bottom Line

The Choppiness Index is a valuable tool for traders and investors looking to gauge market volatility and identify whether a market is trending or ranging. By understanding the calculation and interpretation of the index, traders can better adapt their strategies to current market conditions and potentially improve their overall trading performance. However, using the Choppiness Index alongside other analytical methods and recognizing its limitations is crucial to make well-informed trading decisions. As with any trading tool or indicator, practice, and experience will help refine the use of the Choppiness Index, allowing traders to navigate various market environments more effectively. By incorporating the Choppiness Index into a comprehensive trading strategy, investors and traders can better understand market dynamics and capitalize on potential opportunities in both trending and ranging market conditions.
