TRIX, developed by Jack Hutson, is a momentum oscillator that filters short-term price fluctuations and market noise through triple exponential smoothing. TRIX shows the rate of change of the rate of change, identifying trend direction, momentum, and potential reversal points.
EMA1 = N-period EMA(Close) EMA2 = N-period EMA(EMA1) EMA3 = N-period EMA(EMA2) TRIX = [(EMA3(today) - EMA3(yesterday)) / EMA3(yesterday)] × 100 Or: TRIX = (EMA3(today) - EMA3(yesterday)) / EMA3(yesterday) × 10000 Standard period: N = 14 or 15 TRIX Signal Line = M-period moving average of TRIX (typically M = 9)
Standard TRIX (14 periods): Most commonly used
Short-term TRIX (9-12 periods): More sensitive, suitable for short-term trading
Long-term TRIX (18-21 periods): Smoother, suitable for long-term trend analysis
TRIX Signal Line: Applies moving average to TRIX, generates crossover signals
TRIX > 0: Upward momentum, bullish
TRIX < 0: Downward momentum, bearish
TRIX Crosses Above Zero: Changing from decline to rise, buy signal
TRIX Crosses Below Zero: Changing from rise to decline, sell signal
TRIX Crosses Above Signal Line: Buy signal
TRIX Crosses Below Signal Line: Sell signal
Bearish Divergence: Price makes new high but TRIX doesn't, signals weakening upward momentum
Bullish Divergence: Price makes new low but TRIX doesn't, signals weakening downward momentum
TRIX Slope: Increasing slope indicates strengthening momentum, decreasing slope indicates weakening momentum
TRIX effectively filters market noise through triple smoothing, generating more reliable but lagging signals. TRIX is best used for identifying medium to long-term trends and trend reversals. Zero line crossovers are important trend signals; TRIX above zero indicates uptrend, below indicates downtrend. TRIX divergence is powerful reversal signal, especially when occurring near key support/resistance. Many traders combine TRIX with price action analysis, entering when TRIX confirms trend.
Effectively filters market noise, more reliable signals, strong divergence prediction capability, suitable for medium to long-term trend analysis, simple and intuitive
Very significant lag, not suitable for short-term trading, fewer signals in ranging markets, may miss early trend, requires patience waiting for signals
