Tips for primary direction beginners:
Recommend data:
Use only charts with minute precise data from birth certificates of people with well known biographic data. My best data came from friends, workmates and family - the other from astro.com Astro Databank search. Did not trust times with full minutes like 18:00, 18:15, 18:30. Don't do any birth time rectifications.
Recommend method:
Start using traditional 'zodiacal semiarc primary directions' (in some programs called Placidus semiarc method) without use of planet latitudes. This method is known since Ptolemaeus and is the most widely used form doing primary directions! Beginn with direct directions and use Ptolemy or Naibod key. Use only main aspects - absolut beginners should only use conjunction, opposition and squares to get a feel for hit dates.
Recommend events:
Start doing directions for live changing events. Like sudden deaths, heavy accidents, or if you include trine aspects sudden big success. To get the confirmation that this primary direction method works.
Don't focus to much on hit dates. They can be off by about +-0,5 year but mostly they are much closer. Much more important is that the planet symbols match the event! For this good astrologic symbolic knowledge is required.
Primary directions often show the big picture, meaningful events, times where your captain is on the rudder. Don't forget to view them graphically to see them in full context. Some overwhelming events even can be suppressed, that its hard to recall them later or they are negated.
Recommend software for beginners: https://sourceforge.net/projects/morinus/
Use Morinus Version 8.10. Margheritas article (she linked to in her reply) shows the settings in Morinus for the Placidus semiarc method.
After viewing the primary direction list, do a right mouse button click on a primary direction in that list. In the popup context menu click "PD in chart celestial". In the opening chart window do again a right mouse click. In the popup menu chose 'Windows' and then in the context menu on the right 'Comparison'.
Now you see the natal chart in the inner wheel and the primary directions in the outer wheel for the direction and date you clicked on in the primary direction list. Its a good practice to maximize the chart window. In the little date window you can change the date. Confirm with a left mouse click on the button 'Show' (don't use the button 'OK', because it closes the date window). The outer wheel primary directions are now updated to the new date.
After that the right mouse button and the context menus are your best friends to navigate between different views.
Try to become family with 'Morinus'. Read the menu / help manual. For example try to change the general chart look under menu/options/appearence. In there change 'Themes' to 'theme2' etc...
For later use (from easy to nasty topics):
Personally I still use direct Placidus semiarc primary directions without planet latitudes with Naibod key despite years of comparing all different kinds of primary directions. I only do directions of Asc, MC and all planets from Sun to Pluto. In my oppinion they all work well if you are aware of their symbolic. (I didn't noticed any effects using asteriods, centauers or other minor bodies. Nothing to say about fixstars, because I never used them). Only the main aspects are used.
Methods:
Placidus semiarc, Placidus under the pole and Topocentric primary direction hit dates are often close to each other (maximal approx. 8 months) - Regiomontanus differs more like its house system differs more from Placidus and the Topcentric ones. Ptolemy or Naibod Key compared to other keys can differ years. Even more difference can be seen if a planet is directed which can reach a high amount of latitude like Mercury, Venus, Mars or especially Pluto.
Keys:
The Ptolemy and Naibod keys are working best. In my experience the Naibod key is slightly more precise. Because I have no doubt about this, I didn't spend much thoughts on that. Other than, that a static key fits the nearly constant rotation of the earth around its axis most. Dynamic keys like Placidus or Wim Van Dam key don't meet this criterion.
One possible reason why the Naibod key is working so fine: If its not understood as the mean daily motion of the sun that cannot be precise because of its average value. But as the nearly constant daily progression of the RAMC (MC measured in right ascension).
Planet latitudes:
A confusing part to me was that some include planet latitudes for primary direction calculation. The astrology I know till 30 years is all about planets that are projected on the ecliptic measured in longitude. For example all natal and synastry horoscopes or transits are calculated this way.
If planet latitudes really matter, then a primary directed planet calculated including latitude should only be compared to a natal horoscope that is calculated including planet latitudes too - either both (significators and promissors) should be calculated with latitude or both without. Otherwise its like comparing apples with pears.
Direct and Converse?
Direct primary directions are the strongest in my opinion. When I did beginn using converse primary directions I did only the so called 'neo-converse' directions. They did produce reliable results, but weren't as strong as the direct ones.
But then Martin Gansten teach me in his book how traditionally converse directions are done. I already wasn't happy to handle direct and converse directions. Because sometimes direct and converse hit dates contradict each other and the pure number of hit dates is more than I like to handle. But then I realized that there might be even more, four directions types:
In direct motion of the earth:
Direct: A promissor is carried towards the significator
Converse: A significator is carried torwards the promissor
Earth in converse motion (backwards in time)
Neo-Direct: A significator is carried torward the promissor
Neo-Converse: A promissor is carried torward the significator
The following tests didn't show that traditionally converse directions are stronger than neo-converse once. For one natal chart the traditionally converse directions showed a important missing hit date and for another natal chart the neo-converse once got the missing link. For conjunctions and oppositions the hit dates don't even differ, but all other aspects do.
That overwhelming complexity wiped out all my hopes that primary directions can bring more clarity into my predition work. Now it seemed it's just the opposite.
After didn't touching primary directions for a couple of months, I did have done only direct primary directions since then.
I don't want to miss primary directions. But the enthusiasm is gone. You can get lost in them using them.
Thoughts on tradition:
A reason why primary directions are traditionally judged as the best prediction technique might be influenced by the astronomical possibilities at a given historical time period.
In early times precise future transit calculation of the planets wasn't available. But they could observe planet positions quite well and could calculate the rotation of the earth. So they combined both and developed primary directions. They were judged best, because it was the best that could be done at that time.
Maybe they were lucky too. Because even astrologers that are no 'believers' of the tradition are able to verify that primary directions are still one of the best, if not the best prediction technique today.
Think of the time it needed to calculate a single precise primary direction in the old days. And than compare it with today's minute precise birthday certificates, biographies in books, TV and internet, precise ephemerides and astrology programs with various primary direction calculations. It is said: 'The appreciation is based on the price that was paid for it'. May be there a problem with the price today?
Outlook:
One reason why primary directions are not getting the attention they deserve today is their presentation in list form. We are used to look in a visual way on horoscopes. For example we show transits and solar arc directions in the outer wheel of a natal horoscope located in the inner wheel.
A graphic view of this kind for primary directions I only found in 'Morinus' (which isn't exact in this graphic presentation as it is in its list data).
So I did program this feature in an own Windows program that can show zodiacal primary directions in the outer wheel of an natal horoscope accurate to the second. The natal planet and house data are shown on the left side of the chart, whereas the primary direction data is shown on the right side of the chart. You are able to navigate through time in any step very fast. Studing a given period of live, this graphical view makes it very clear what is going on.
But that does work only with direct and neo-converse primary directions. Till now I wasn't able to find a solution to show traditional converse directions this way.
In future I hope for more sophisticated visual representations hopefully in full 3D. But unfortunately good astrologers aren't good programmers. One look at the programs we got today is very chastening.

Which book do you mean. Persian Nativities Volume 1, 2 or 3?
@All
I like to learn more about techniques that are related to primary directions - like the bounds. Are there any good book recommendations that show primary directions in combination with related or other techniques that are known for their reliable results?
