Triple EMA Oscillator (TRIX)

Created by Jack Hutson, TRIX is the rate of change for a 3 EMA smoothing of the price over a lookback window. TRIX is often confused with TEMA. [Discuss] 💬

chart for Triple EMA Oscillator (TRIX)

// C# usage syntax for Trix
IEnumerable<TrixResult> results =
  quotes.GetTrix(lookbackPeriods);

// usage for Trix with Signal Line (shown above)
IEnumerable<TrixResult> results =
  quotes.GetTrix(lookbackPeriods, signalPeriods);

Parameters

lookbackPeriods int - Number of periods (N) in each of the the exponential moving averages. Must be greater than 0.

signalPeriods int - Optional. Number of periods in the moving average of TRIX. Must be greater than 0, if specified.

Historical quotes requirements

You must have at least 4×N or 3×N+100 periods of quotes, whichever is more, to cover the warmup and convergence periods. Since this uses a smoothing technique, we recommend you use at least 3×N+250 data points prior to the intended usage date for better precision.

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<TrixResult>

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 3×N-3 periods will have null values since there’s not enough data to calculate.

⚞ Convergence warning: The first 3×N+250 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

TrixResult

Date DateTime - Date from evaluated TQuote

Ema3 decimal - 3 EMAs of the price

Trix decimal - Rate of Change of 3 EMAs

Signal decimal - SMA of Trix based on signalPeriods periods, if specified

Chaining

This indicator may be generated from any chain-enabled indicator or method.

// example
var results = quotes
    .Use(CandlePart.HL2)
    .GetTrix(..);

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

// example
var results = quotes
    .GetTrix(..)
    .GetRsi(..);
