Letters to Technical Analysis
I have an understanding of Fourier analysis from being an old-time EE. Not a lot of depth. I would like
more information on the Volume 1 and Volume 2 disks. I have Volumes 1 and 2 of Technical Analysis of
Stocks & Commodities; also an IBM PC.
Do you have any further literature or a phone number I can use to call you?

Dear Mr. Vilas
Volumes 1 and 2 computer disks are currently only available in Apple II computer format. We intend to
supply them as subroutines for IBM DOS at a later date.
Fourier analysis has proven to be an excellent method for optimizing or tuning filters such as moving
averages or momentum that are commonly used to smooth out daily stock or commodity data. In late
1980, I obtained some software that purported to implement a Fourier analysis designed for stock and
commodity data. I found that it was sorely lacking in all respects a my understanding of Fourier spectral
analysis. Therefore, in early 1982, Dr. Warren and I implemented a preprocessed and optimized Fast
Fourier Transform specifically designed for use with stock or commodity data. These routines are
published in Volumes 1 and 2 of Technical Analysis of Stocks & Commodities magazine and have been
proven to be both accurate and reliable over time. - EDITOR
