Homodyne Discriminator
Estimates the dominant cycle period using a homodyne approach.
Usage
Use to measure the instantaneous dominant cycle period from price data. Feed its output into adaptive indicators as the dynamic period parameter.
Background
Described in Rocket Science for Traders (2001), the Homodyne Discriminator borrows from radio engineering to measure instantaneous frequency by multiplying the analytic signal by its one-bar-delayed conjugate, giving cycle period without DFT latency.
Formula
\[
\text{Period} = \frac{360}{\text{atan}(Im / Re)}
\]
