CCollins:
The so called FFT in MS is a loser. The dominant cycle always comes up as
the length of the time period of the data. The so called cycles bear little
resemblance to anything useable. Excel spreadsheets supports FFT.
Parenthetically I have never come across anyone who uses MS FFT for trading.
I have met many people who collectively use almost all the rest of the
functionality of MS,
Since the movements in the stockmarket are not truely periodic, is there any
evidence that linear or non-linear Fourier analysis can be applied to the
stockmarket?
