## Triple Exponential Moving Average Oscillator (TRIX)

### Description

The Triple Exponential Moving Average Oscillator (TRIX) by Jack Hutson is a momentum indicator that oscillates around zero. It displays the percentage rate of change between two triple smoothed exponential moving averages.

### Formula

$EMA_{1} = EMA1_{n-1} + \frac{2}{(n + 1)} \times (P_{n} - EMA1_{n-1})$

\(EMA2 = EMA2n-1 + ((2 / (n + 1)) * (EMA1n - EMA2n-1)))\

\(EMA3 = EMA3n-1 + ((2 / (n + 1)) * (EMA2n - EMA3n-1)))\

\(TRIX = (EMA3n - EMA3n-1 ) / EMA3n-1)\

Where:

• Pn =the current price.
• EMA1n-1 = the exponential moving average value of n periods back
• EMA2n-1 = the exponential moving average value of n periods back
• EMA3n-1 = the exponential moving average value of n periods back
