Who this entry is for — Readers studying the principle of synchronicity in the post-book Hurst tradition who need to avoid extending it automatically to highs.
In the formulation popularised by David Hickson, cycles of different wavelengths have synchronized troughs wherever possible. Because the durations do not coincide, not every trough of a shorter cycle can align with a trough of the longer cycle.
Peaks are not synchronized. The sum of nested cycles and the underlying trend can shift and deform the highs observed in price.
What it means
| Event | Correct reading |
|---|---|
| Troughs of several cycles align | Consistent with the principle of synchronicity |
| Short-cycle trough without a long-cycle trough | Normal: the shorter cycle completes more iterations |
| Peaks do not align | Expected in Hickson's formulation, not a model error |
| Trough observed in price | May be time-translated relative to the ideal trough of the cycle |
“Synchronized” does not mean that all troughs must fall on the same bar. The source says “wherever possible” and provides no universal tolerance in bars. The window must therefore be an explicit part of the phasing method adopted, not a rule attributed to Hurst or Hickson.
What it does not demonstrate
A visual alignment:
- does not by itself demonstrate that the phasing is correct;
- does not automatically assign a higher probability to a trade;
- does not authorise moving troughs until the model “fits”;
- does not make peaks and troughs symmetrical;
- does not replace an invalidation rule.
The synchronicity trick is a post-book procedure reported by Hickson: it uses signals from shorter cycles as an early indication of a longer trough. It must be distinguished from the plain meaning of the term.
Provenance
This entry was checked against concept 7 of David Hickson's 10 Core Concepts of Hurst Cycles. The document presents the principle as part of Hurst's theory, but it is a later source: Cyclepedia does not treat it as a direct quotation from the Cycles Course, whose primary text is not currently available in the collection.
