The TRIX oscillator was developed by Jack Hutson in the 1980s. The TRIX displays, the percent rate of change, of 3 iterations of an exponentially smoothed moving average of an instrument. Oscillating around the zero line, TRIX is designed to filter out stock movements that are insignificant to the larger trend. The user may change the input (close) and period lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below. Click here for more information.


How To Trade Using TRIX

If the TRIX crosses above the SIG a sell signal will be generated, Conversely, if the TRIX crosses below the SIG a buy signal will be given.
