How it works
The module displays a set of ready-made formulas, each utilizing selected astrological objects from the specified chart dials. After selecting the desired row, the program calculates the final coordinate and immediately moves:
- The Chart Pointer, or
- The Movable Dial — if the corresponding element is active in the settings.
Formula Symbols
Special symbols are used in the formulas:
- + — sum of object coordinates
- − — difference of coordinates
- / — half-sum (midpoint between two objects)
- // — double half-sum (an extended midpoint calculation used in the HSA system)
Selecting the Active Formula
Radio buttons are located in the far-left column. Selecting a row activates the corresponding formula and sets the Pointer to the calculated position.
Changing Objects in a Formula
Each object in a formula can be changed manually:
- Left-click on the desired cell.
- A list of available objects will open.
- Select the required object. The dial number from which the object is taken (if multiple dials are involved) is selected in the exact same way.
Dial Linking
If the Dial Link button 
is activated, changing the dial number in one column automatically and synchronously changes the dial numbers in the other columns of the formula.
This is convenient for comparative analysis of multiple charts, transits, directions, and synastry.
Swapping Objects
Objects within formulas can be swapped without needing to reselect them from the menu:
- Hold down Ctrl
- Drag the object with your mouse to another column This allows you to quickly rearrange formulas and test different combinations.
Built-in Panel Mode
As shown in the screenshot, the Hamburg School Formulas block can be used as a standalone pop-up window or as a built-in module in the program’s right panel for constant, quick access.
