Quick Definition

A triple-smoothed exponential moving average oscillator that filters market noise and identifies trend direction and momentum changes.

Key Takeaways

  • TRIX applies three layers of exponential smoothing to filter market noise
  • Zero-line crossovers indicate trend direction changes
  • The triple smoothing reduces false signals but introduces more lag than single-smoothed indicators
  • Signal line crossovers and divergences provide additional trading signals

What Is TRIX?

TRIX (Triple Exponential Average) is a momentum oscillator that displays the percentage rate of change of a triple-smoothed exponential moving average (EMA). The indicator applies three successive EMAs to the closing price, then calculates the one-period percentage change of the final smoothed value. This triple smoothing process effectively filters out short-term market noise, making TRIX useful for identifying the underlying trend direction and significant momentum shifts. TRIX oscillates above and below a zero line — positive values indicate bullish momentum, negative values indicate bearish momentum. Trading signals include: zero-line crossovers (TRIX crossing above zero is bullish, below zero is bearish), signal line crossovers (TRIX crossing its signal line, similar to MACD), and divergences between TRIX and price. The default period is typically 15, though this can be adjusted based on the trading timeframe. TRIX is particularly valued for its smooth nature, which reduces whipsaws compared to other momentum oscillators, though this smoothness comes at the cost of a slight lag in signal generation.

TRIX Example

  • 1TRIX crosses above zero after spending three months in negative territory, signaling a long-term trend change from bearish to bullish.
  • 2A bearish divergence between price making new highs and TRIX making lower highs warns of an impending trend reversal.
