# 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]

```
// usage 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 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### Utilities

See Utilities and helpers for more information.

## 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(..);
```
