The Bradley siderograph was developed in the 1940ies by Donald Bradley to forecast the stock markets (link book). Bradley assigned numerical values to certain planetary constellations for every day, and the sum is the siderograph. It was originally intended to predict the stock markets. The noted technical analyst William Eng singled out the Bradley model as the only 'excellent' Timing Indicator in his book, "Technical Analysis of Stocks, Options, and Futures" (source: Astrikos).
It is crucial to understand what the siderograph is about since many traders (and even financial astrologers) misunderstand it. Over the decades it has been observed that the siderograph can NOT (!!!) reliably predict the direction but only turning points in the financial markets (stocks, bonds, bonds, commodities) within a time window of +/- 4 calendar days (in some cases up to +/- 1 week). Inversions (i.e. a high instead of a low and vice versa) are quite common.
The Bradley siderograph is still the favorite of site visitors, below please find the standard model for 2013.
It's eye-catching in the chart 2013 that there are many tiny spikes. Actually one could mark 11 dates in the standard model between February & June 2013. With a window of +/- 1 week almost every day would be marked as a potential turn - which is meaningless. Moreover, with such flat counter-trends even a tiny change in the formula leads to date change, making the turning dates not statistically not robust at all.
- The multi-year Bradley highs in March-June 2008 (triple top) nailed the all-time highs in EUR/USD & oil as well as bull market highs in gold, silver, wheat, soybeans & corn.
- The 2-year siderograph low on 12/14/08 nailed the 12/18/08 low of the 70% oil bear market, as well as bear market lows in gold, silver & euro.
- The 1.5 year low in the summer of 2010 coincided with the annual lows in equities, oil & precious metals.
- The 4-year high on 3/16/12 coincided with very important tops or bull market tops in equities, oil, precious metals & euro.
- In December 2012/ January 2013 we have a 2-year low, and in June 2013 the highest printing since mid-2000 (inflation-adjusted equity highs). Therefore the first half of 2013 should see the final (weak?) rally in the inflation markets, before the decline into the 4-year low in late 2014.
From Q2/2009 until early 2012 we had a strong negative correlation of intermediate-term reversals, i.e. ‘normal' Bradley highs were lows in stocks & the other inflation markets (and vice versa). This ‘paradoxical' reaction seems to be correlated with the crack-up boom that started in the second quarter of 2009. ‘Crack-up boom' is a paradoxical oxymoron (like ‘irregular pattern') for a paradoxical time. With the fading out of the crack-up boom in late 2011/ early 2012 this correlation is also fading now. In the period of transition 2012/13 we presumably neither have a reliable positive nor negative correlation, i.e. only the dates count (without a polarity).
In 2011 the Bradley siderograph could not beat random probabilities by much, when taking all turning points into considerations. Only the major turning points (bold & large in the chart) continue to be valuable timing tools *today*.
Strictly speaking the siderograph dates are potential turning dates, bifurcation points in the language of chaos theory. In addition to the standard model there are 3 other models in the premium area, which may be quite different. All Bradley analyses in the free area since 2007 can be found here.
Raw data for your own research
Premium subscribers of Amanita Market Forecasting get the data of the four Bradley models for the period 1990-2020 as a .txt file (click here to subscribe). Another possibility: you calculate the data yourself with the aid of a financial astrology software - please go to the software-page. I mainly use the Market Trader von Alphee Lavoie, which is too expensive for the average hobby researcher though.
