TRIX
The percentage rate of change of a triple-smoothed exponential moving average of price.
Formula
TRIX = Percentage change of EMA(EMA(EMA(Close, n), n), n)
Unit
%
In depth
Triple smoothing removes almost all short-term movement, so TRIX produces very few signals and lags heavily — it is deliberately at the far end of the noise-versus-lag trade-off. The zero line matters most in practice, since it marks where the triple-smoothed average stops rising or falling. Because it is expressed as a percentage change it is comparable across securities, unlike MACD. Its rarity of signals is the point; whether those signals are useful is an empirical question this dictionary does not answer.
Worked example
A triple-smoothed EMA moves from 498.20 to 499.10. TRIX = (499.10 - 498.20) / 498.20 x 100 = 0.18%. Readings this small are normal, because three rounds of smoothing leave very little variation.
