TRIX
Momentum oscillator showing the percent change in a triple-smoothed EMA; the extra smoothing filters minor fluctuations and cycles below the signal period.
EMA1 = EMA(Close, n); EMA2 = EMA(EMA1, n); EMA3 = EMA(EMA2, n); TRIX = (EMA3 − EMA3_prev) / EMA3_prev × 100
TRIX applies an EMA three times to closing prices, then calculates the daily percentage change of the final triple-smoothed value. The triple smoothing gives TRIX exceptional noise-filtering properties — short-cycle fluctuations that pollute RSI or MACD are almost completely removed.
A positive TRIX reading means the triple-smoothed EMA is rising; negative means falling. Traders use a signal line (9-period SMA of TRIX) similarly to MACD: crossovers trigger entries, and divergences identify turning points. TRIX works best on longer timeframes where its lag is acceptable.
