Dimitri,
is it really important to keep lastvalue in
error=LastValue(<FONT
color=#0000ff>Cum(abs(y-detrend)));
because in c++ I can write the code without lastvalue,
but of course the result s different

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
