The TRIX indicator calculates the rate of change of a triple exponential moving average. Developed by Jack K. Hutson.
TRIX(price, n = 20, nSig = 9, maType, percent = TRUE, ...)
Price series that is coercible to xts or matrix.
Number of periods for moving average.
Number of periods for signal line moving average.
Either:
A function or a string naming the function to be called.
A list with the first component like (1) above, and additional parameters specified as named components. See Examples.
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.
A object of the same class as price
or a vector (if
try.xts
fails) containing the TRIX values.
The TRIX is calculated as follows: 3MA = MA
( MA
(
MA
(price
) ) ) trix = 100 * [ 3MA(t) / 3MA(t-1) - 1 ]
