But I don't think that all these toys will work. Now we can do all that research using formal math approach.
Look, you mentioned this:
The hypothesis is that 15,30,60,75,120 aspects of the progressed moon to any planet from the charts mentioned results in a favourable move in the stock while, 45,90,105,135,165 from the progressed moon to any planet results in an unfavourable move. while aspects of 0,150 and 180 are variable although he states that conjunctions are usually bullish and oppositions usually bearish, he also states that aspects meanings are reversed when the progressive moon is aspected to a retrograde planet.
The period of the progressed Moon is 27.32 years. Mathematically it means that these favorable/non favorable periods will be repeated every 27.32 years as simply progressed Moon passes the same zone of Zodiac, whatever direct or inverted Natal chart, whatever direct ore retrograde Natal planet - this is the same 27.32 years cycle. Mathematically it means that 27.32 years cycle should be active. Let check it. I have downloaded monthly data for Dow since 1789 (!) and calculated spectrum for this data set:
