I’ve just recorded a You Tube video on called Planetary Symmetry showing how symmetrical natal midpoints create very sensitive axes for future transits.
We know by reading TTTA that Gann was using the Gemini rising chart for the 4th July 1776.
I have applied my Cosmic Midpoint Map to this natal chart which locates the most sensitive natal midpoints and plots the expected result with colour panels according to a legend. Basically Red and Black are negative transits and Blue and Green are positive transits to midpoints.
Using the Gemini rising chart for the US- I plotted the CMM with the Dow, it highlights very significant negative periods in history like: The Great Depression, WW1, WW2, 1987 crash, 911, lows of 2002 and 2003, and the Global Financial Crisis.
To see the charts, you can watch my video at this link.
