Hilbert Transform Timing from Smoothed and Detrended Price Data

Article BigQuant

Summary

The document presents a short-term timing approach based on the Hilbert transform. It assumes price movements contain a long-term trend, shorter cyclical fluctuations, and noise. The proposed process first smooths the data with a 20-period moving average, then differences it to reduce the long-term trend, and applies the transform to estimate the signal’s phase. A positive imaginary component is interpreted as bullish and a negative one as bearish.

The explanation describes the transform as shifting phase by 90 degrees and uses rotation in the complex plane as an intuition for reading cyclical behavior. It cites a securities research report as background, but includes no performance figures, test design, or risk controls. The signal may be unreliable when the assumed cycles are weak or unstable; the text itself notes occasional jumps between neighboring quadrants and invites further refinement.

Key ideas

  • The method assumes price can be separated into trend, shorter cycles, and noise.
  • It smooths prices with a 20-period moving average and differences the result before applying the Hilbert transform.
  • A positive imaginary component is treated as bullish, while a negative component is treated as bearish.
  • The document offers a conceptual rationale but no empirical performance evidence or risk management rules.
