FourierSeriesIndicator

The Fourier Series Indicator performs the Fourier transform on the price data based on the first three harmonics extracted by the Bandpass Filter. The output data is a waveshape plot synthesized from the extracted harmonics. The recreated waveshape can help identify price cycles.

In addition to the primary waveshape plot, the Fourier Series Indicator calculates its rate of change. When the rate of change crosses the zero level, the wave could be taking a turn signifying a possible trend reversal.

Input Parameters

Parameter Description
length The amount of bars in the primary cyclic component in the data.
bandwidth The tolerance of the measurement of the cycle period.

Plots

Plot Description
Wave The Fourier series-synthesized waveshape.
ROC The waveshape's rate of change.
ZeroLine The zero level.
