Hi PL,

Aspect shapes are not taken into account in horary. I'm pretty wary of them in natal astrology too. There are too many variables, such as the orbs used etc. It also depends on a very accurate time. They can change within minutes.
If you are particularly interested in yods, Karen Hamaker-Zondag wrote a great book on the topic, which included unaspected planets. Funnily enough its called 'Yods'. I think it is one of her better books.
Cheers
Sue
