Hi Tragapips,

Regarding Fourier:

1-There is some of the ANG indicators which is basically a Fast Fourier transform applied to price,If I can find it in one of my computers I will post here for you.

2-I do not think Fourier is very useful for live trading..Due to the fact that Fourier constantly self evaluates,the Fourier transforms for any moment in time can be subsequently changed.
It is not that it repaints,it is that the nature of Fourier transforms is repainting

Regarding Cyles:

1-If you have not already done so,buy/download/whatever JMHURST "The profit magic of stock transaction timing"..in spite of the title this book is the bible of anybody that wants to apply cycles to any market..I started making money the moment I understood it.
Hurst wrote it in 1973,and believe me,33 years later you can make a ton of money by just understanding its principles and applying them to any market.

2-Download the digital filter generator(posted by newdigital somewhere in this Forum,just do a search).There are 2 versions,English and Russian,choose the one that suits you and play with it for your favorite currency pairs and timeframes..enjoy the results

3-If you are able to apply what Hurst teaches for moving averages using digital filters instead of smas..well someday you will post your own Tragapips con man
