[amibroker] Help with Tomasz's Example on FFT

[Paul Ho]

Hello, I’ve been going over Tomasz’s example on FFT that he published on with the release of 4.87 beta. So far so good with the exception of the last plot statement   Plot( cos( phase[ sbar * 2 ] + (sbar) * x1 * 2 * 3.1415926 / Len ), " dominant cycle "+ Len/(sbar) + "(" + sbar + " bin) bars", colorBlue, styleOwnScale );   It seems that this statement is plotting the weighting factor of the fourier transform   Wk = cos(2πk/N + φ) Where φ is the phase angle and k is the no of harmonics in the series. If this is the case, how is it related to the dominant cycle.   Any explanations will be greatly appreacriated.   Thanks Paul. __._,_.___ Please note that this group is for discussion between users only.
