From the Ankara horary perspective:
Mercury (significator), in own sign, so it does not have a potential special relationship with any other planet because Mercury disposits itself.
Jupiter (significator) in Libra; significator Jupiter is disposited by another planet, Venus, so Venus has a potential special relationship with significator Jupiter: now, Venus itself is disposited by yet another planet, and such a chain (of dispositorships) could go on and on: IN ANKARA HORARY, ANY "DISPOSITOR OF A DISPOSITOR" DOES NOT PLAY A ROLE IN THE DELINEATION OF THE ANSWER TO THE HORARY QUESTION.
So, here in your practical example, ONLY VENUS (significator Jupiter's dispositor) would be looked at AND ONLY IN ANY CONJUNCTIONAL OR ASPECTUAL RELATIONSHIP IT MIGHT HAVE WITH significator JUPITER (for example, the dignity or detriment of Venus would play no role whatsoever in the delineation) Now, does Venus have a conjunctional or aspectual relationship with significator Jupiter? If YES, then such a relationship would either be + or - testimony relative to the question; if NO, then there would be no input of testimony whatsoever relative to the answer to this question.
PLEASE NOTE THAT REGULAR HORARY DOES NOT OPERATE BY THE ABOVE EXPLANATION. In regular horary, various planets (such as dispositors of planetary significators) are (or could be) investigated as additional factors, persons, influences, relative to the horary answer: within regular horary, "who" or " what" some primary or secondary dispositor of querent or quesited significator or co-significator "is", can be pertinent (according to regular horary) to the question. In Ankara horary, this is not the case.
