Lesson / WY-02-08
A bar’s price range is H-L, the range covered during the observation period. Body length is |C-O|, the net change retained from open to close. Upper-wick length is H-max(O,C), and lower-wick length is min(O,C)-L. All four use the same price units but answer different questions: range measures coverage, body measures the start-to-finish result, and wicks measure how far extremes lie beyond the open and close.
