Dont rubbish astrological finance !!
Some people treat companies as people, in that they take the birthday, and cast a horoscope, identifying rising sign, ascendant, planetary conjunctions etc.
These should be unique for each company.
As beachrunner has explained, this is more detailed than the newspaper rubbish.
Based on the unique horoscope, a futurescope can be cast.
Also be aware, that astrology is about "possibilties" not that certain events WILL happen at a certain time.
Astrology is more about about "there are tides in the affairs of man, when taken at the flood, lead to great fortune" - more guidelines than exact details.
Gann used the Venus-Neptune Trine to predict highs/lows.
They seem to work, even in 1987 !!
As with all things, they dont work all the time. ( no system ever does ).
The BIGGEST mistake people make is take a planetary configuration and apply it to EVERYTHING.
That would imply EVERY company in the world woudl behave the same way at the same time -this is absurd.
Also, consider Hindu astrology, as mentioned previously - this process may contradict the western astrology.
Also, there is Chinese astrology !!
A lot of study would be required to ascertain which is the valid one ( or which is more accurate under which circumstances ).
However, consider donaldduke remarks about it not being important what you use, since if you cut your losses and let the profits run, you achieve positive expectancy anyway !!
