tema
Syntax
tema(X, window)
Please see TA-Lib Functions for the parameters and windowing logic.
Details
Calculate the Triple Exponential Moving Average (tema) for X in a sliding window of the given length.
The formula is:
\(ema1 = ema(x, window)\)
\(ema2 = ema(ema1, window)\)
\(tema = 3 * ema1 - 3 * ema2 + ema(ema2, window)\)
Examples
$ x=12.1 12.2 12.6 12.8 11.9 11.6 11.2
$ tema(x,3);
[,,,,,,11.24444444444444]
$ x=matrix(12.1 12.2 12.6 12.8 11.9 11.6 11.2, 14 15 18 19 21 12 10)
$ tema(x,3);
