TRIX Indicator: Filtering Out the Market Noise
The Logic of Triple Smoothing: Understanding TRIX
Developed by Jack Hutson in the 1980s, the TRIX (Triple Exponential Average) is a momentum oscillator that uses a unique three-layer smoothing process. Most moving averages suffer from a choice: they are either too fast and noisy, or too slow and lagging.
TRIX solves this by calculating a 1-period rate-of-change of a triple-smoothed EMA. This process filters out 'insignificant' price movements while keeping the core direction of the trend intact. It's especially powerful for trend traders who want to stay in a trade through minor pullbacks.
TRIX vs MACD: Which Has Less Lag?
While the MACD is a 'Difference' of two EMAs, the TRIX is the 'Rate of Change' of one triple-smoothed EMA. This makes the TRIX mathematically 'Steeper' and faster to respond to trend changes compared to the MACD.
In professional day trading, the TRIX is prized for its ability to filter out 'False Crossovers' that frequently occur with the standard MACD. It identifies structural momentum regimes rather than just simple price interaction.
{ TRIX Execution Checklist }
Primary Setup: Triple Exponential Smoothing
Bullish: TRIX crosses above Signal Line
Bearish: TRIX crosses below Signal Line
Avoid: Trading crossovers near the Zero-line (Noisy)
Zero-Line Rule: Higher than 0 means bullish regime
Stop-Loss: Place beyond most recent swing fractal
Strategy: Signal Line Crossovers and Zero-Line Rejections
Signal Crossovers: Similar to other oscillators, we use a 'Signal Line' (usually a 9-period EMA of the TRIX). A cross above the signal line is a bullish trigger. The Zero-Line Rejection: In a strong uptrend, the TRIX will stay above zero. If it pulls back but 'Rejects' (bounces) off the zero-line without crossing into negative territory, it’s a high-probability continuation signal.
Optimization: Settings for Day Trading vs. Swing Trading
For Day Traders, a 14-period TRIX is the standard. It provides a balanced view of intraday momentum. For Swing Traders, extending the period to 30 or 50 helps identifies major cycle shifts, ensuring you only enter when the 'Big Money' is moving in one direction.
