The TRIX indicator calculates the rate of change of a triple exponential moving average. The values oscillate around zero. Buy/sell signals are generated when the TRIX crosses above/below zero. A (typically) 9 period exponential moving average of the TRIX can be used as a signal line. A buy/sell signals are generated when the TRIX crosses above/below the signal line and is also above/below zero.
The TRIX was developed by Jack K. Hutson, publisher of Technical Analysis of Stocks & Commodities magazine, and was introduced in Volume 1, Number 5 of that magazine.
