What is TRIX?
TRIX is the one-bar rate of change of a triple-smoothed exponential moving average. Introduced by Jack Hutson in Technical Analysis of Stocks & Commodities magazine in the early 1980s, it runs the close through an EMA three times with the same length, then plots the percentage change of that heavily filtered series from one bar to the next. The line oscillates around zero: positive while the triple-smoothed trend is rising, negative while it is falling.
The triple pass is the point. Each smoothing stage suppresses cycles shorter than the chosen length, so TRIX ignores fluctuations the filter deems noise, at the cost of lag. Common published settings run the same length (15 bars is typical) through all three passes, with a shorter EMA of the TRIX line itself serving as a signal line.
How traders use it
- As a trend-regime read: the zero line separates a rising filtered trend from a falling one, and staying on one side of zero defines regime the way centerline rules do on faster oscillators.
- For signal-line crossovers: TRIX crossing its own EMA turns earlier than the zero cross, mirroring MACD signal-line practice with more smoothing behind it.
- For divergence against price at swing extremes, where the heavy filtering makes divergences rarer but less prone to one-bar noise.

TRIX FAQ
What does the TRIX indicator measure?
TRIX measures the percent change, bar to bar, of an exponential moving average that has been smoothed three times with the same length. In effect it is the slope of a very smooth trend proxy: positive readings mean the filtered trend is still rising, and a cross below zero means it has turned down. The triple smoothing is designed to filter out cycles shorter than the chosen length.
What is the difference between TRIX and MACD?
MACD is the spread between two EMAs of different lengths, so it reacts whenever the fast average pulls away from the slow one. TRIX is the rate of change of a single triple-smoothed EMA, so it reacts only when the filtered trend itself changes slope. Both oscillate around zero and pair with signal lines; TRIX trades responsiveness for noise suppression.
