Converse transits are simply transits that count backwards the same amount of days from the date of the event. The mid-point being the date of birth. It is a technique that is not well known, but is incredibly effective.
Let’s take a look at some examples:
-Daniel Negreanu. Rectified Birth Time: 1:26:48 (UT) by F.M.
Event: Defeat in a 1v1 poker tournament against Phil Hellmuth. June 23, 2021.
He has Natal Neptune 180 MC Orb: 57′. At the time of the tournament, in secondary directions, Neptune is opposing the MC with an orb of 0.6′!
Converse Saturn 180 MC. The orb is 6°30′ on the last day of the event, which is the maximum allowed orb for transits.

-Logan Paul. Rectified Birth Time: 8:10:40 (UT) by F.M.

These converse transits also work not only on people, but also on stocks. If you check the earnings report for the Microsoft stock on April 2022 using converse transits, you can see Jupiter on the MC, signifying a positive earnings report and an upward movement in the price of the sock.
