How to calculate "good" and "bad" periods for somebody's Natal chart

As my University teacher said: "The exactly formed question resolves 50% of the problem".

It is very important to form your question correctly, especially when you would like to consider good and bad periods based on your Natal chart. So, you have to ask yourself first: "What does it mean GOOD and BAD?". In astrology, this question is not about your well (or not so well) being. According to classical astrology, GOOD periods are the periods when planets form so called GOOD aspects (60 and 120 degrees). Therefore, BAD periods occur when planets form  BAD aspects (90 and 180 degrees). The quality of the conjunction (0 degrees) depends on involved planets. 

If you are actually interested in something else, you must specify your question: "Good for what?" - and then apply appropriate astrological techniques to answer your question. As an example, if what you are really interested in is MONEY, you should consider your second house (and maybe 6th and 8th - depends on MONEY type) and watch periods when so called "good" planets (as a rule, Venus and Jupiter are the first choice for money) pass this house, taking into account the aspects they form, receptions, aspects from other planets to the second house, etc.

In this class I discuss the simplest example - periods of "good" and "bad" aspects. More advanced combinations are possible to consider with Timing Solution. When you understand the simple example and are able to produce it yourself, you will be able to do more complicated things. The logic is the same.

So, let's work with the aspect model.

First of all, prepare the program to do the task. You need to define the analyzed interval (TMin/TMax):

It is just the interval to see the aspects.

Then click "Calculate":

and click here to browse ULE panel:

The program is ready to do any search for you.

The second step is to define what you want the program to do. In our case, it is the aspects model. So, divide all aspects that occur within your chosen interval on GOOD guys (60 and 120 degrees aspects) and BAD guys (90 and 180 degrees aspects).

Run ULE Model Editor:

and fill out this form:

After the calculation you well see in the Main Screen how these GOOD guys work:

This diagram shows the level of activity of these guys. The higher diagram the more GOOD aspects are involved.

Exactly in the same manner define BAD guys (90 and 180 degrees aspects):

Now you have two diagrams that represent a work of these GOOD and BAD guys:

Now you need to find a balance between GOOD (red) guys and BAD (blue) guys.

Look at the model editor; it uses L1- a condition designated to GOOD guys and L2 - BAD guys:

Type this "L1-L2" formula and click "Calculate" to find the balance between these guys:

The resulting "balance" curve is now in the Main window:

GOOD and BAD aspects are shown together (the upper part of the diagram) and separately (below).

What we have done is just that: we have created a model of good and bad aspects within some chosen interval. This model is tied to your Natal chart. However, to make any statements regarding these aspects and other things (like market forecast, the growth of your personal income, success of your trading, your emotional feelings, etc.) - it is not enough. It is just a first part of equation. Then you need to have a different data set (market ups or downs for that time interval, your profit/loss tracking, your trade diary) in the same time scale, compare it to the aspect model that you have made above, - and only then the statistical analysis and creation of forecast models is possible.
