Theory :
TRIX (triple exponential average (TRIX) indicator is an oscillator used to identify oversold and overbought markets, and it can also be used as a momentum indicator. It is using EMA for calculation
This version :
Is using the “Double smoothed Wilder’s EMA” variation instead of using “regular” EMA for TRIX calculation. That makes it faster in response to market changes than the original TRIX indicator
Usage :
You can use this version the usual way – change of color can be used as a signal
