A daily price bar whose session has closed — the only kind a call is ever graded against.
Once a session closes and its settled open/high/low/close arrive, the day's bar is final. Grading reads final bars only, and a call whose call-day bar is missing stays a stranded call rather than being scored against a neighbouring day.
Final bars are the ground truth for every number on the site: hit rates, session moves, and the price cards on stock pages.
