Here are some basic rules and established orbs.

-Use the pure symbolism of the planets and the exact meaning of the houses involved.
-Use the topocentric house system.
-The charts used need to be rectified to +/- 4 seconds or else the aspects would be out of orb or simply disappear.
-An inharmonic aspect between benefics signals a positive event. (Venus 90° Jupiter)
-A harmonic aspect between malefics signals a negative event. (Mars 120° Saturn)
-Direct houses/planets/nodes in both direct and converse movement.
-Orbs for the personal planets are 11', for Saturn and Jupiter 8', for the outer planets (Ur, Neptune & PL) 2'-3'.
-The progressed moon can reach an effective orb of 18' in normal aspects and 32' in conjunctions and oppositions.
-The moon simulates the right hand of a clock because of its rapid motion.

The following are from "Prediction II", by Alexander Marr:

SEONDARY DIRECTIONS IN ORDER OF EFFICACY:

1. Maturation of radical aspects (luminaries, planets, angles and cusps of houses) as in the radices of Ronald Reagan and Queen Elizabeth II. (*In our first event, Tyson has loose sextiles from Jupiter to his angular Ur/PL conjunction in his radix, it matures on the day the event takes place)

2. Progressions and regressions of the angles and cusps of houses to radical factors

2a. Planets progressed and regressed aspecting radical factors.

3. Angles and cusp of progressed houses to progressed or regressed planets to regressed.

3a. Planets progressed to planets progressed, or returned to returned.



Demonstration of technique using events in the life of Mike Tyson:

*Important events occur due to the accumulation of aspects from various directions and multiple predictive methods. We don't use one predictive technique to forecast.
*Key for reading the abbreviations is at the end.

The sensitive points are obviously the Asc. MC and the house cusps, these are the points that make a chart individual because they are based off of the exact birthplace and the exact time of birth, planets in houses/angular come second in strength.

This is why its important for the astrologer to know how everything is calculated.

Also something that is very important but no one uses is the prenatal epoch. It is no less important than the widely used and overrated birth chart. Sometimes a persons destiny is better seen in his prenatal epoch.

On the day Adolf Hitler became Chancellor of Germany—in the primary system of directing—in his prenatal epoch, MC was 0° Sun.
