"When Time and Price square, Change is bound to happen"

W.D Gann






W.D. Gann, “The Tunnel Thru the Air” (1927)

A highly coded book, that W.D. Gann advised to read three times, and in which he said he has concealed some of his secrets. For those who have a lot of time to invest in research ! Many people have embarked in the adventure. Bonnie Lee Hill made very interesting discoveries on weather cycles ( Uranus / Neptune) that Gann mastered well it seems , Ivan Petter Amundsen made some on the title of the book itself. Others have spent a fortune on expensive and often unnecessary seminars, sometimes taught by people who themselves had taken these courses and seeked revenge ... Those who found and published something interesting are listed below ( P.Mikula, J.Long, Bradley Cowan and a few others ). Gann is probably one of the first to have applied astrology to finance in such a detailed way. See the article on WD Gann for more ... but not all!



And for the Brave who want to read W.D.Gann’s original writings, this is a good place to start:

 Gustave Lambert Brahy, « La clef de la prévision des évènements mondiaux et des fluctuations économiques et boursières » (1932) – Editions Traditionnelles (translated in english by Norm Winski).

This is the first and maybe the only basic financial astrology manual still available today. Lambert Bragy is THE precursor of what will become the Siderograph Bradley.

A short book (77 pages) analysing US economic cycles.


John Mars Langham, “Planetary Effects on Stock Markets” (1936)

Louise Mc Whirter, “ Astrology And Stock Market Forecasting” (1938)

Un des classiques de l’astrologie financière, très souvent cité pour l’analyse du cycle des nœuds lunaires (voir dans la rubrique « Test »). L’ouvrage contient aussi une analyse en détail de la période 1850-1950 et une méthode de prévision basée sur la Nouvelle Lune précédant le mois à analyser, qui est mise en relation avec le thème du NYSE, ainsi que des règles d’analyse des thèmes d'incorporation de sociétés (ceux incorporés dans le Delaware ayant l'avantage d'être horodatés).

 A classic of Finacial astrology, often quoted for the cycle analysis of the Lunar nodes (see the "Test"). The book also contains a detailed analysis of the period 1850-1950 and a forecasting method based on the New Moon preceding the month to be analyzed, which is using with the chart of the NYSE, as well as some rules of analysis for incorporation chart of companies (those incorporated in Delaware having the advantage of being time-stamped).


G. Bayer

Bayer was also as a prolific author as W.D. Gann, also publishing his roman à clef and famous for its 48 trading rules, very precise in their definition, but which have not been studied comprehensively to check if they really worked consistenly.

A good site for those who want to dig deeper:


And for those who want to read Bayer’s original writings :

  • "Bible Interpretation” (1937)
  •  “A complete Course in Astrology” (1937)
  • “Time Factors in the stock market” (1937)

Finally, a Classic :


Donald Bradley, “Stock_Market_Prediction” (1950)

The basis of many models and softwares... His book is easily found on the internet.

It starts with chapters on Jupiter / Uranus and Venus / Uranus cycle but the real interest sits with the description of an arithmetic model of planetary influences: the Siderograph, which uses Mundane transits of the main planets (excluding the Moon) and using the only aspects of 0°, 60 ° and 120 ° ( defined as positive ), and 90 ° angles of 180 ° and defined as negative . A combination of two planets is given a value that begins to grow with a 15 ° orb to reach its maximum at 0 ° and go down again as the aspect separates to 15° . Declinations of Mars and Venus are also taken into account.

This simplistic model has had its heyday, it works on some years and has seen countless attempts to improve it: adding planets ( asteroids, dwarf planets), and all the missing angles. Its main drawback is that it gives more points of inflection that the direction of the market . It can not account for the complexity of interactions with 4, 5 or 6 planets that are not the sum of their values, but can switch from the positive to the negative, a phenomenon also known as “Inverted signal”.
