What the hell is that reason for selling in the first place? LOL.

Anyway, if you're just trading and not holding, while selling at higher prices is definitely better, I don't think there's anything wrong with selling early. If you sold early and the price rose higher, hey, you just played it safe and secured profits. There's really nothing wrong with that.

Hindsight is 20-20. There's no way for you to know for sure that the price was going to go up and not the other way around. Stop kicking yourself for it.
