Found the right stock and still managed to enter it at the worst possible time

Had META showing RS most of the morning, strong D1, good volume and it kept holding near HOD every time SPY pulled back, so naturally I got impatient and bought while SPY was pushing higher instead of waiting for another market pullback. Entry was around 718.50$, then SPY reversed almost immediately and META came back with it, putting me underwater before the setup ever had a chance to work. I kept SPY up next to moon and META actually held up pretty well through the pullback, so I stayed with it and eventually got out green when the market bounced. Worked out but looking at it afterward I basically picked the stock correctly and then removed most of the advantage by chasing the entry.
