TRIX

0th

Percentile

Triple Smoothed Exponential Oscillator

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

Usage
TRIX(price, n = 20, nSig = 9, maType, percent = TRUE, ...)
Arguments
price

Price series that is coercible to xts or matrix.

n

Number of periods for moving average.

nSig

Number of periods for signal line moving average.

maType

Either:

  1. A function or a string naming the function to be called.

  2. A list with the first component like (1) above, and additional parameters specified as named components. See Examples.

percent

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

Other arguments to be passed to the maType function in case (1) above.

Details

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

Value

A object of the same class as price or a vector (if try.xts fails) containing the TRIX values.

Note

Buy/sell signals are generated when the TRIX crosses above/below zero. A nine-period EMA of the TRIX is used as a default signal line. Buy/sell signals are generated when the TRIX crosses above/below the signal line and is also above/below zero.
