Letters To S&C by Technical Analysis, Inc. TRIX: TRIPLE EXPONENTIAL SMOOTHING OSCILLATOR Editor, I am very interested in the indicator called TRIX, which was first described and presented by your publisher, Jack Hutson, in his July/August 1983 article in STOCKS & COMMODITIES, “Triple Exponential Smoothing Oscillator: Good TRIX.” I have a question about its calculation. At the website StockCharts.com, there is a graph of a TRIX calculation plotted around what I call a zero baseline with values above zero of 10%, 20%, 30%, and 40%, and values below zero of 10%, 20%, and 30%: http://stockcharts.com/school/doku. php?id=chart_school:technical_indicators:trix My question is simple. How would I plot my own TRIX indicator values for various stocks around a zero baseline by hand? In other words, after doing the TRIX calculations for a given stock using a pen, paper, and handheld calculator, how would I take those values and graph them around a zero baseline? What are the necessary calculations (in layman’s terms, since I am not a mathematician or computer programmer)? I have spent a great deal of time researching this question on the Internet and am only asking you as a last resort. Any help will be greatly appreciated. MARK MCGEE
