TRIX - Triple Exponential Average

Printer-friendly versionPDF version
The TRIX indicator is a momentum indicator designed to calculate the percent rate of change of a triple exponentially smoothed moving average. It is very similar in the way the MACD indicator works. Both indicators provide basically the same methodology behind generating market momentum and directional movement.

TRIX was designed to filter out the minor, less significant moves within a market trend. This is done, just as other traditional indicators have done in the past, by utilizing multiple moving averages.

Convergence and Divergence are common uses of the TRIX indicator. Adding the trigger line crossover provides the trader with a Buy/Sell Signal generated from the crossing of the two moving averages.

Calculation

To calculate TRIX, first pick a period with which to create an exponential moving average of the closing prices. For a 15-day period the calculations would look like this:

Calculate the 15-day exponential moving average of the closing price.

Calculate the 15-day exponential moving average of the moving average calculated in step #1.

Calculate the 15-day exponential moving average of the moving average calculated in step #2.

The result is triple exponentially smoothing the moving average of closing prices, greatly reducing volatility.

Finally, calculate the 1-day percent change of the moving average calculated in step #3.

Buy/Sell Signals

A buy signal occurs when the TRIX value crosses from below the trigger line to above the trigger line. A sell signal occurs when the TRIX value crosses from above the trigger line to below the trigger line.
