Every card's official result is its frozen 72-hour basket return, credited in the direction the card called (a short call that falls scores positive). Categories rank by the equal-weight average return per settled card — count-fair, so a category with thousands of cards has no edge over one with a dozen. Win rate is the share of settled cards with a positive directional return. Trader P&L counts live positions only, never paper trading. Categories need 10 settled cards to rank; until then they run as Qualifying.
