TRIX (Triple EMA Rate of Change, period 15)Momentum

Timeframe M1 · unit %

What it measures

TRIX computes the percentage 1-bar change in the triple-smoothed EMA (EMA applied three times, each with period 15) of the close price. The triple smoothing removes cycles shorter than the EMA period, leaving only the dominant momentum direction. Centered on 0 by construction.

How Janira reads it (bullish vs bearish)

A positive TRIX means the triple-EMA is rising - the dominant smoothed trend is pointing upward. A negative TRIX means it is falling. Because of the extreme smoothing, TRIX filters out almost all short-term noise; only sustained momentum registers. Small movements near zero are genuinely indeterminate.

In plain language

TRIX applies the EMA formula three times - first to prices, then to that result, then again. It is like hearing a melody after triple noise cancellation. The result changes slowly but when it does change direction, it reflects a genuine momentum shift rather than random jitter.

Scenarios

TRIX positive and accelerating: the triple-smoothed trend is not only rising but rising faster - a deep, confirmed upward momentum state.
TRIX positive but decelerating toward zero: the triple-smoothed trend is still upward but slowing down - upward momentum is fading at the highest level of smoothing.
TRIX crossing zero: the triple-EMA has changed direction - a significant but delayed signal that the dominant trend has shifted. False signals are very rare here because of the extreme smoothing.
TRIX diverging from price for multiple bars: price has made new extremes, but the triple-smoothed trend has not - the most noise-filtered view of momentum disagrees with raw price action.

Janira computes TRIX (Triple EMA Rate of Change, period 15) deterministically from live price action, the same way for every reading - no discretion, no hidden weighting. This page explains the method; it is not a live reading and not advice.
