  Stephane,you may see now the comparison of my AFL 
  Elementary Fourier analysis and the usual FFT. There is a significant 
  error decreament but, the most important, a much better fundamental period 
  approximation.The sample was 921 bars of the Nikkei C1=MA(RSI(50),100); 
  and the FFT analysis was executed in DaDisp_SE2000.Any suggestion to 
  make my analysis faster would improve the sinusoidal approximation and 
  would give an interesting T/A toolDimitris Tsokakis--- In
