TRIX¶
Indicators · Momentum
Triple-EMA smoothed rate of change, ×10000 for readability.
TRIX is a momentum oscillator that's been put through a noise filter three times over. It measures the rate of change of a triple-smoothed moving average, so the random tick-to-tick wiggle that plagues raw momentum is almost entirely scrubbed out. What's left is a clean, slow-turning line that crosses zero on trend changes and gives high-quality divergence reads — momentum with the static removed.
How it works¶
The block smooths the Source with an EMA three times in succession over the Period (default 15), then takes the one-bar rate of change of that triple-smoothed series and scales it (×10000) so the small numbers are readable. That's the TRIX line. A Signal line — an EMA of TRIX over Signal period (default 9) — gives you a crossover trigger, and the block exposes ready-made Bull ↑ / Bear ↓ arrows for when TRIX crosses its signal. TRIX oscillates around a zero line in a sub-pane: above zero, triple-smoothed momentum is positive; below, negative.
When to use it¶
TRIX is for traders who want momentum signals without the whipsaw. Use the zero-line cross as a slow, high-conviction trend-change signal, and the signal-line cross for earlier (still filtered) entries. Its triple smoothing makes it one of the better tools for divergence — because the line is so clean, a disagreement between price and TRIX stands out clearly. The trade-off is lag: all that smoothing means TRIX confirms turns late, so it's a confirmation tool, not a leading one.
Example¶
A filtered momentum entry: wire bars into TRIX and feed the Bull ↑ crossover into a Buy Signal, but only while a 200-EMA bias is up (combine through an And gate). The triple smoothing keeps you out of the noise that a raw Momentum or MACD would react to. Protect with a Fixed Stop-Loss and backtest in the Tester.
Tips & gotchas¶
- Smoothest momentum here — and the laggiest. Great for cutting noise, poor for catching the exact turn.
- Zero-line cross = trend, signal cross = timing. Use them together, like MACD.
- Excellent for divergence thanks to the clean line — one of its strongest uses.
- Longer Period = even smoother and slower. Don't shorten it so far that you reintroduce the noise it exists to remove.
