Choppiness Index

Created by E.W. Dreiss, the Choppiness Index measures the trendiness or choppiness on a scale of 0 to 100, to depict steady trends versus conditions of choppiness. [Discuss] 💬

// C# usage syntax
IEnumerable<ChopResult> results =
  quotes.GetChop(lookbackPeriods);

Parameters

lookbackPeriods int - Number of periods (N) for the lookback evaluation. Must be greater than 1. Default is 14.

Historical quotes requirements

You must have at least N+1 periods of quotes to cover the warmup periods.

quotes is a collection of generic TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Response

IEnumerable<ChopResult>

• This method returns a time series of all available indicator values for the quotes provided.
• It always returns the same number of elements as there are in the historical quotes.
• It does not return a single incremental indicator value.
• The first N periods will have null values since there’s not enough data to calculate.

ChopResult

Date DateTime - Date from evaluated TQuote

Chop double - Choppiness Index

Utilities

• .Condense()
• .Find(lookupDate)
• .RemoveWarmupPeriods()
• .RemoveWarmupPeriods(qty)

See Utilities and helpers for more information.

Chaining

Results can be further processed on Chop with additional chain-enabled indicators.

// example
var results = quotes
    .GetChop(..)
    .GetEma(..);

This indicator must be generated from quotes and cannot be generated from results of another chain-enabled indicator or method.
