Thanks Fred, I found a number of articles by Anthony Warren in S&C  with some codes in Basic which is frankly rather difficult to comprehend.
but the description was good enough to be able to code it in afl/scripts.
 
What I found of interest was his mentioning of perfiltering using moving averages and resampling, aiming to remove high frequency noises, but no mentioning of detrending ( = removing low frequency components)
 
any thoughts on that?
 
Paul.

Yes ... I have had it running in AFL / VBS for quite awhile ...

If you look at old ( 83 - 84 ) issues of TASC you'll note that there
were others using maximum entropy years before Ehler's first
mentioning it in public.
