The Triple Exponential Moving Average (TRIX) is a powerful technical analysis tool designed to help traders determine the momentum of a price as well as identify overbought and oversold conditions in an underlying financial asset. TRIX was developed by Jack Hutson in the early 1980s, and as its name suggests, it is used to show the rate of change in a triple exponentially smoothed moving average. Functionally, TRIX can be used as an oscillator as well as a momentum indicator. When used as an oscillator, it shows potential peak and trough price zones; and when used as a momentum (or trend following) indicator, it can filter out spikes in the price that are irrelevant to the overall dominant trend. TRIX has also been described as the ‘impulse indicator’ that is capable of pointing out when there is a growing or sinking impulse in the market. Broadly, TRIX belongs to the Oscillators group of indicators. Other indicators similar to TRIX include the MACD (Moving Average Convergence Divergence) and RVI (Relative Vigour Index).
TRIX, which is a triple smoothed EMA, is essentially an EMA, of an EMA, of an EMA, hence the “triple”. Exponential moving averages usually place more weight on current price data as opposed to simple moving averages that just calculate the average of prices, with equal weighting to all price data. Most trading platforms use a default 14-period when calculating TRIX, but the parameters can be adjusted according to the needs of the trader.
Here are the steps followed when calculating a 14-period TRIX:
The calculation above will compute a TRIX indicator that swings above and below 0, generating positive and negative values.
TRIX is built on a triple-smoothed exponential moving average (EMA) of closing prices, which helps filter out market noise while highlighting underlying momentum. Two key parameters control its behaviour:
Tailoring TRIX settings to your preferred timeframe and volatility tolerance helps ensure signals land when you’re ready to act—so you’re not constantly second-guessing minor price wobbles.

As mentioned above, TRIX can be used as both a trend following indicator and as an oscillator. As a trend following indicator, positive TRIX values imply that an uptrend is in place whereas negative TRIX values denote that a downtrend is in place in the market. When TRIX values run along the 0 value (centreline), it implies that the market stance is neutral. As an oscillator, TRIX is used to watch out for overbought and oversold conditions in the market. Extreme positive values denote overbought conditions, while extreme negative values denote oversold conditions in the market.
Here is how to trade the different types of TRIX signals:
As mentioned above, TRIX can help determine the ‘impulse’ of the market. With the 0 value as a centreline, if it crosses from below, it will be an indication that the impulse is growing in the market and traders can seek opportunities to place buy orders in the market. In the same manner, a cross of the centreline from above will signal a shrinking impulse in the market and traders can seek opportunities to place sell orders in the market.
To pick out optimal entry points, traders add a signal line on the TRIX indicator. The signal line is basically a moving average of the TRIX indicator, and as such, it will always lag behind the TRIX. A signal to place a buy order will occur when the TRIX crosses the signal line from below. Similarly, a signal to place a sell order will occur when the TRIX crosses the signal line from above. This is applicable in both trending and ranging markets. In trending markets, a signal line cross will signal that a price retracement is over, and the main trend will resume. In ranging markets, a signal line will confirm that resistance and support zones have been upheld in the market.
Divergence between price and TRIX can signal a looming reversal before it shows on the chart itself. There are two main types:
How to Use Divergence
Rationale
Divergence spots hidden shifts in momentum that pure price analysis can miss. By combining TRIX readings with chart structure, you gain early warning of reversals—so you can prepare your entries or exits ahead of the crowd.
Analysing TRIX across several timeframes helps you filter noise and align entries with the dominant trend. Follow this workflow to balance responsiveness with reliability:
Aligning TRIX signals across multiple horizons cuts down on false alarms—so you trade with greater confidence, knowing you’re riding the main trend.
Enhancing TRIX signals with complementary tools helps you filter noise and confirm momentum before committing to a trade.
Layering TRIX with oscillators or trend-defining moving averages sharpens signal quality—so you’re more likely to act on moves that have both momentum and structural support.
Even a robust indicator like TRIX can give misleading signals if you don’t account for its limitations. Here are two frequent pitfalls—and simple fixes:
Acknowledging TRIX’s sensitivity to market structure helps you pre-filter unlikely signals—so your trades reflect genuine momentum shifts rather than random fluctuations.
By now, you’ve seen how TRIX’s triple-smoothed EMA design cuts through market noise and highlights true momentum shifts. You’ve learned to:
Consistent, disciplined use of TRIX in varied market conditions builds both statistical edge and trader confidence—so you can act decisively when opportunities arise.

Start with the default 14-period and single smoothing—this balances signal speed and noise reduction so you can focus on learning momentum basics.
Use daily charts to spot major trends and 4-hour or 1-hour charts to fine-tune entries once you’re comfortable with the indicator.
Look for divergence at key support/resistance or confirmation from a secondary tool (e.g. RSI above 50 for bullish signals).
Yes—TRIX adapts to forex, stocks, commodities, and indices, but always adjust period length to match each market’s typical volatility.
A cross above zero signals growing upside momentum, while a cross below zero suggests increasing downside strength.
