TRIX: the one-bar percent change of a triple-smoothed 18-bar EMA, plotted with a 9-bar signal line.
Overview
TRIX shows momentum with heavy smoothing, in its own pane around zero, with a signal line in orange.
Colors are green while TRIX is above its signal and red while below.
How it works
Smooth the close three times with an 18-bar EMA. TRIX = one-bar percent change of that triple EMA. Signal = 9-bar EMA of TRIX.
The triple smoothing filters out small moves. Because it is a percent change, TRIX readings can be compared across symbols.
How to use it
- Some traders watch TRIX crossing its signal line.
- Use zero-line crosses as trend changes in the smoothed price.
- Look for divergence between TRIX and price.
- Use it to ignore short noise and focus on larger swings.
These are ways some traders read it, for learning. They are not trade signals.

Notes and limits
- Works on any symbol and timeframe; it only needs candle data.
- It lags because of the triple smoothing.
- Its zero line marks where the triple-smoothed average stops rising or falling.
