The aspect is only by sign, not by degree. That shows a link but its a weak link compared to a degree based aspect. The Moon originally had an orb of 13 degrees, being around its average daily movement. However the separation here is nearly twenty degrees.
Even if it was in orb, the sextile is the weakest of the major aspects and the one that is least likely to produce a perfection of the matter (unless supported by other factors, such as reception between the significators).
I think that is why some writers might identify it more with possibilities and opportunities because it's too weak to produce certainties except with support, rather than it leads in some special way to the desired outcome.
If the two planets were in orb, then there would be Reception in this case but they are not. Sign based aspects were not used by Lilly or other late Medieval or Seventeenth Century Astrologers and they have not been used since the late Hellenistic and early Medieval periods.
That doesn't mean they are not effective in the sense of producing an effect, they are but that effect wil very rarely produce a successful outcome - the only ones I can think of that would are those involving a mutual reception, for example Mercury in Taurus and Venus in Virgo.
Thanks for sharing your view on sextile! I have seen events asked taking place from charts with sextile with wide orb (13-15 degrees) . That made me think that sextile denotes good chance of things happening if the chart and circumstance also support such outcome.
As for receptions, do you consider essential dignities as one of them? (i.e. triplicity, terms, face & etc?) I see some readers count those as receptions at different strength. If that's true then this chart shows one sided reception from questied to querent which is moon in Capricorn receives Saturn as ruler and at term. Since we know that querent is willing to form a romantic relationship with the questied and the questied also recieves querent, would it be fair to say that there is a chance of them getting together?
