Donald Bradley Stock Market Astrology Predictions 4


Donald Bradley, who also wrote under the pseudonym “Garth Allen,” is most widely known for having developed the Bradley Siderograph stock market indicator (i.e., the “Bradley Barometer“).  The Bradley Siderograph takes into account a variety of planetary aspects rather than looking at one in isolation.  This is important because although there may be one planetary aspect that is negative, there could simultaneously be several significant planetary aspects that are very positive and outweigh the one negative aspect.  Under the name Donald Bradley, he wrote several books including those listed below.

Solar and Lunar Returns – An Exercise in Sidereal Astrology

Donald Bradley wrote this book expressly for the beginner.  The book covers all the planetary aspects and positions to provide a new perspective on the underlying meanings of planetary vibrations in everyday life.  It also contains illustrations with examples of how Solunar Returns have predicted events in the lives of ordinary people.

The book provides instructions on how to cast and interpret Solar Returns and Lunar Returns based on the Sidereal Zodiac of the Constellations.  It is based on the Sidereal Zodiac because, in Bradley’s view, it is the most accurate system of predicting future events.  Click here to watch a short YouTube video on the difference between solar time and sidereal time.

Stock Market Prediction – The Planetary Barometer and How to Use It

This work is probably the best known of the books Donald Bradley published during his lifetime.  The Bradley Siderograph mentioned in this book is a unique forecasting tool that takes into account all of the major planetary aspects rather than focusing on only one or two at a time.  This provides a richer view, and Bradley should be commended given that he did his work without the use of a computer.  BradleySiderograph.com should provide more than enough of an overview of this book to give you a good sense for they key knowledge it contains.

    I am a follower of JM Hurst’s cycle work. He, and a number of his predecessors, mentioned briefly the cause of cycles in markets as potentially being due to planetary/magnetic relationships. Where Hurst measured the actual cyclic price movement, you are measuring the cause of the price movement. The real question is, how do you know if it works? Are there backtest results available?

    Nice Bradley chart.
    I have a copy of his book and built my own version a long time ago.
    Needless to say, my dates vary slightly from yours.
    I am curious. What is your input data source?
    I used a NASA JPL website, and calculated both Astrometric and Observed positions.
    I am also curious about your scaling methodology from 0 to 100.

    Thanks
    Jim

      Hi Jim,

      Thanks for your kind words. The Bradley Siderograph charts on this site are based on the JPL Planetary and Lunar Ephemeris DE406. In my view here are a few items that could be leading to differences. I believe the last item mentioned below, Weighting, could be one of the driving forces behind any differences. (1) Rounding — If in the intermediate calculations numbers are rounded to a fewer or greater number of decimal places, it could result in a difference. I used 2 decimal places for rounding. (2) Time of Day and Location — I used noon for New York City. Using a different time of day/location could result in differences. (3) Orb of Aspect — Donald Bradley recommends using a 15 degree orb of aspect based on the sine curve, which he found to be more accurate than an “isosceles triangle” type of weighting. For this site I used the orb of aspect values published at the end of his book in Table IV: “Sine Curve Values for Natural Orb of Aspect.” Different orbs of aspect could lead to different results. (4) Weighting — In “Stock Market Prediction,” Donald Bradley wrote that the Long Terms “may be given considerably more weight by multiplying it 3, 4, or 5 times, depending upon choice after experimentation.” I used a multiplier of 5 for the Long Terms for this site, but the use of a 3, 4, or other multiplier could have contributed to a different result.

      The methodology of the Bradley Bars assigns a value between 0 and 100 for each day depending on the “strength” of the Turn Date. I developed this to provide an indication of the significance of each Turn Date. The methodology to arrive at these values is somewhat complex, but overall the objective is to identify Turn Dates from an objective mathematical methodology as compared to judgmentally.

      I hope this helped, and congratulations on producing your own version of the Bradley Indicator. It is not an easy endeavor, and I commend you for taking the time and effort necessary to put it together.

      Regards,
      Matt
