Although I’m not a
mathematician, my appetite for indicators
was stimulated by John
Ehlers’s March 2000
S&C article, "Hilbert
Indicators Tell You When To Trade."
Thanks to the lucid explanation of lag
elimination in exponential moving averages, I have been able to apply the
technique to the Lotus 1-2-3 spreadsheets that I use for stock charting.
However, a similar application of the
Hilbert transform to identifying cycles
within a historical stock-data string
eludes me. I confess to not possessing a
program that uses EasyLanguage and
ask if you can refer me to a suitable
article detailing the use of the transform
with a spreadsheet. I may say I am
averse to taking a black-box approach
when it comes to generating indicators.

Thank you for writing. Sorry, we haven't
published an article on the Hilbert transform with a spreadsheet approach. See
also the next letter. —Editor
