Cardinal Cross and Ordinal Cross

The numbers that fall on the blue lines form what’s known as the
“Cardinal Cross”
and the numbers that fall on the red lines running into the
corners of the square, form what’s known as the “Ordinal Cross”.
Any numbers that fall on these lines are said to act as
significant support and resistance levels.
So the Square of nine is an interesting arrangement of numbers
that have a specific order and can be used in many different
ways.
The red and blue lines intersect with other and divide the
square in 8 equal parts.
The angle between each line is 45 degrees
