TTR (version 0.13-1)

TRIX: Triple Smoothed Exponential Oscillator

Description

The TRIX indicator calculates the rate of change of a triple exponential moving average. Developed by Jack K. Hutson.

Usage

TRIX(price, ma1 = list("EMA", n=20), ma2 = ma1, ma3 = ma1,
              ma.sig = list("EMA", n=9), percent = TRUE)

Arguments

price

Price series to use.

ma1

A list whose first component is a string containing the moving average function name; additional parameters may also be specified as named components.

ma2

See ma1.

ma3

See ma1.

ma.sig

Similar to ma1, but for the signal moving average.

percent

logical; if TRUE, the rate of change is calculated using the ROC function, otherwise the momentum function is used.

Value

• A vector containing the TRIX values.

Details

The TRIX is calculated as follows: 3MA = ma3( ma2( ma1(price) ) ) trix = 100 * [ 3MA(t) / 3MA(t-1) - 1 ]
