when mercury retrograde is charted to btc there is often more correlation then just chance could dictate. Retrograde dates are observable from earth by following the apparent motion of the planet. Mercury appears to slow down, stop, start moving backwards, then reverses course again, and speeds up. These movements of mercury when placed on a BTC chart are fun to make -this one is from earlier in the year as reference, I'm charting the next retrograde which started a week ago and goes right through the election- lots of interesting correlations. Publishing incoming BTC/Retrograde and Theta/Retrograde soon. Please let me know if there is a TA/Astrology chartyou would like to see!
