James Marsden Hurst 1924—2005

After the book — Hurst post-1970

The mature method: from the Cycles Course (Cyclitec, ≈1973) to the Hickson tradition — phasing analysis, the FLD, the eight principles and the diamond notation. With one rule: book first.

A quién sirve esta entrada — The 1970 book is not all of Hurst: a few years later, with the Cycles Course, the method matured into a different form — fewer formulas, more chart reading. This is the index of the complementary path: what is there, where it comes from, and why it belongs after the book's eight stages.

Fuente: JM Hurst's Cycles Course (Cyclitec Services, ≈1973) and the modern teaching tradition — David Hickson, Sentient Trader, hurstcycles.com. None of this page is in The Profit Magic of Stock Transaction Timing (1970): whenever Cyclepedia draws on the course or the tradition, it says so.


The three layers of the Hurst corpus

Layer Source What it holds
1 · The book Profit Magic (Prentice-Hall, 1970)
2 · The course Cycles Course (Cyclitec, ≈1973) The mature graphical method: phasing analysis, FLD, eight principles, diamond notation
3 · The tradition Hickson / Sentient Trader / hurstcycles.com Operational FLD, software, intraday extensions, modern teaching

Hurst himself regarded the course as the method behind his operating results; the book is its public ancestor — and the theoretical foundation stays the same (the appendices hold for both).


  1. The eight principles — the book's five plus the course's three (harmonicity, synchronicity, cyclicality)
  2. Phasing analysis — dating every component's lows: entry, extension, completion
  3. The diamond notation — phasing's handwriting on the chart
  4. The underlying trend — the longer cycles' direction as a filter
  5. Time translation — why peaks slide and troughs do not
  6. The FLD — the line displaced half a cycle forward, with its ruler
  7. The synchronicity trick — confirming the long trough with the short cycles

Book and course, side by side

Profit Magic (1970) Cycles Course (≈1973)
Method Mathematical: nested envelopes, centred averages Pattern recognition: phasing of troughs
Projections Extrapolated crossings and averages Full cyclic model, FLD
Strength Objective rules, well-defined cyclicality Complex markets, variation and skew
Limit Fragile when cyclicality dries up Requires practice and chart judgement

Book first — The course assumes everything the book proves: the model, the principles, the discipline of the barriers. Tackling phasing and FLD without the recorrido de oro's eight stages is learning calligraphy before the alphabet.
