For item trades and pet trades, it is how much silver you have
earned selling the pets/items for the week. For breeding offers,
it is how many players have accepted your breeding offers, ranked
based on total amount of offers per player. Arena, it is how many
wins your pet has gotten this week. This means, for arena, it is
possible for 1 player to have 10 pets on the top 10 spots,
meaning they get 100 gold for that week.
