TRIX Momentum Oscillator and Triple Exponential Smoothing

Summary

TRIX is described as a momentum oscillator calculated from the percentage rate of change of a triple exponentially smoothed moving average. The repeated smoothing is intended to reduce the influence of small, insignificant price movements and emphasize broader movement in the underlying series.

The document attributes the indicator to Jack Hutson in the early 1980s and notes that Hutson’s original approach applies the calculation to logarithmic prices. It says some versions omit this step, while the version described follows the original method. No calculation settings, signal rules, market examples, or performance evidence are provided, so the text explains the indicator’s premise but does not establish when it is useful or how it should be traded.

Key ideas

• TRIX measures the percentage rate of change of a triple-smoothed moving average.
• Triple smoothing is intended to filter minor price fluctuations.
• The original method applies the calculation to logarithmic prices.
• The document gives no trading rules or performance evidence for the indicator.
