A prediction whose session has closed and whose open→close outcome has been mechanically scored as correct or not.
A call starts life ungraded. Once its session closes and the day's prices arrive, the grader computes the session's open-to-close return, derives the realized direction, and marks the call correct or incorrect. No human is in the loop.
Only sessions that are fully closed are graded — grading never runs on a live, still-trading session.
