The Bradley Siderograph is one of the most valuable tools of stock market prediction in the field of financial astrology, and I’m excited you’re here to learn more about it. This site provides a general overview of this stock market turning point indicator as well as advanced applications that go beyond the scope contemplated by Bradley’s book.
Origins of the Donald Bradley Siderograph
In 1948 Donald Bradley wrote a book called “Stock Market Prediction: The Planetary Barometer and How to Use It.” This book presented a tool known as the Donald Bradley Siderograph, which is intended to leverage “the potency of major planetary aspects…to prove the correspondence between planetary operations and market responses.” The term “siderograph” means star graph. The ancients saw planets as “wandering stars,” which is how they developed the predecessor word for “planet” in ancient Greek (i.e., “astēr planētēs”).
The Bradley Siderograph is one of the most interesting and popular forecasting methodologies in the field of Financial Astrology. This field involves leveraging astronomical and astrological data to understand and forecast activity in the financial markets. However, Financial Astrology is far broader and richer than this methodology alone, and its origins date back several thousand years.
How to Use the Donald Bradley Siderograph
The siderograph is typically used to identify turning points (i.e., trend reversals) in the market over the medium- to long-term rather than predicting the exact movement of the market across time. Turning points include inversions, which occur when the stock market bottoms when the siderograph tops, or vice versa. Therefore, turning points in the siderograph can indicate both tops and bottoms in the stock market. It is important to not place undue influence on the amplitude of the siderograph. Turning points taking place at the top or bottom of a large crest do not necessarily imply a more significant market turning point. Also, siderograph turning points typically indicate market turning points within 4-7 calendar days rather than being exact to the day of the turning point. Sophisticated market professionals use the Bradley siderograph in conjunction with other fundamental and technical market factors rather than using it alone to inform their trading decisions
The Calculations Behind the Donald Bradley Siderograph
Donald Bradley’s siderograph is based on major planetary aspects and the declinations of Mars and Venus. The siderograph assigns varying weights to each planetary aspect depending on its exactness. For example, if two planets are 90 degrees apart they will receive the full weight for a square aspect (i.e., an aspect of 90 degrees). The siderograph allocates a lower weight to aspects that are close but not exact (e.g., an aspect of 88 degrees, which is close to a square aspect but is not exact).
