I know as a documented recorded written fact, WD Gann predicted the 1930s Depression!Time Cycles:
Time is the most important factor in determining market movements because the future is a repetition of the past and each market movement is working out time in relation to some previous Time Cycle. A serious study of the various Time Periods and Cycles will convince you how the Markets repeats the same price levels under the same Time Periods of some previous cycle. The Great Time Cycles are most important because they record the periods of extreme high or low prices. The most important Time Cycle for markets is the 90 year Time Cycle.
When we subtract 90 years from the present (2020) we arrive at 1930 and America was slipping into a Great Depression with a collapsing price of the NYSE. But, what I find most interesting as an astrologer and student seriously studying the 1930s Great Depression: In 1930 we clearly see a Solar Arc of McWhirter's 1792 NYSE timed chart ASC at 04,40 Scorpio partile 180 NYSE Sun 05,22 Taurus. Today, 90 years later we see NYSE Solar Asc 05,21 Aquarius partile 90 NYSE Sun 05,22 Taurus.
I do know as a fact WD Gann was a serious astrologer and I know as a fact WD Gann was a member of the NYSE. I equate WD Gann scholarship with markets the same as I do for Cyril Fagan's scholarship with Sidereal Astrology. WD Gann being a member of the NYSE was in position to access historical records of the NYSE and other Commodity Markets. I strongly suspect WD Gann was in a position to obtain the exact times for the first timed trades in all the markets. As a young serious Sidereal Astrologer, these first timed trades in the various markets would be priceless, particularly from a pure research point of view.
I strongly suspect WD Gann discovered his “most important” 90 year great cycle by noticing when the ASC of a timed market chart partile 90/180 the Sun of the same market chart with Solar Arcs rates (app 1 year = 1 degree)---price history of a market repeated itself! Of course this proves what we Sidereal Astrologers already know: Astrological Time is governing everything! "Timing is Everything."
IMO, another confirmed economic depression may be somewhat shorten in time length with a Federal Reserve backstopping the economic pain with Stimulus Packages, so at least people will not starve to death. But, until the right drugs are produced to kill/prevent the infection of this Covid-19 Virus--the Federal Reserve can't do anything about this Virus.
