The TRIX indicator, short for "Triple Exponential Average," is a momentum oscillator used in technical analysis to identify trends and potential reversals in price movements of financial assets. Developed by Jack Hutson in the 1980s, TRIX is designed to filter out market noise and emphasize underlying trends by applying triple smoothing to the price data.

The TRIX indicator calculates a series of exponential moving averages (EMA) of the price data, with each subsequent EMA representing a different level of smoothing. By taking the difference between these EMAs, TRIX generates a single line that oscillates around zero. Traders typically interpret TRIX signals based on crossovers above or below the zero line, as well as divergences between TRIX and the price of the asset.

One of the primary applications of TRIX is to identify trend reversals or confirm existing trends. When TRIX crosses above zero, it suggests bullish momentum, while a cross below zero indicates bearish momentum. Additionally, divergence between TRIX and price movements can signal potential trend reversals, providing traders with early warnings of shifts in market sentiment.

Despite its popularity, traders often use TRIX in conjunction with other technical indicators to validate signals and reduce false positives. Like any technical tool, TRIX has its limitations and should be used in conjunction with other forms of analysis and risk management strategies.
