All of Trendsetter Software's Mac products include the ability to plot TRIXTRIX was developed by Jack Hutson, editor of Stocks and Commodities Magazine. It is a one day rate of change of a triple exponentially smoothed moving average of closing prices. Its triple exponential smoothing is designed to filter out "insignificant" cycles. Triple smoothing involves repeating the exponential smoothing process an additional two times. The result is a very smooth curve that filters out all cycles that are less than the time span chosen for the smoothing.
Trades should be placed when the indicator changes direction. You also can also plot a moving average of the TRIX to create a "signal" line (similar to the MACD indicator) and then buy when the TRIX rises above its signal line, and sell when it falls below its signal line.
