This idea is based on the article Time Cycle Oscillators, published in IFTA Journal 2018.
As volumes precede prices, the “period of time cycles” precedes volumes.
Hence, the simple harmonic oscillator SHO (blue) is leading to the volume zone oscillator VZO. The latter is created by Walid Khalil.
Negative and positive divergences between the SHO and VZO help in predicting the direction of the VZO. Also, the SHO confirms and shows the significance of the signals which are generated by the VZO. i.e., the encircled sell signals on the chart.
