Definition

TRIX is a momentum oscillator based on the rate of change of a triple-smoothed exponential moving average.

Why Triple Smoothing Is Used

Applying exponential smoothing three times removes much of the short-term noise before momentum is calculated. The result usually oscillates around a zero line.

How to Read It

A rising positive TRIX supports positive momentum, while a falling negative reading supports negative momentum. Zero-line crosses, signal-line crosses, and divergence can be used as supporting evidence, but the extra smoothing creates lag.

Key Takeaway

TRIX is a heavily smoothed momentum indicator. It filters noise well but reacts more slowly than raw price.

Practical forex example

An index is already in an uptrend. TRIX crosses above zero and continues rising while price holds above support. The indicator supports positive momentum, but a trader still uses price structure to judge whether the trend remains intact.

Why TRIX matters

Understanding TRIX helps traders interpret market information, plan decisions, and manage risk with more context.
