When is the best time during the season to sell off trainees (18 yo)?
in the end of the season, normally trainees are pretty rare and 18yo get good prices but as the poster before me said use the time to train him to that point.
At the end of the season, trainees lose some of their value, because you won't be able to train them much before they age up.
18 yo would be much more valuable at the beginning of the season than the end (unless you train them during the season).
