TRIX {TTR} | R Documentation |
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 |
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:
|
percent |
logical; if |
... |
Other arguments to be passed to the |
The TRIX is calculated as follows:
3MA = MA
( MA
(
MA
(price
) ) )
trix = 100 * [ 3MA(t) / 3MA(t-1) - 1 ]
A object of the same class as price
or a vector (if
try.xts
fails) containing the TRIX values.
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.
