Method of displaying the Spot price on charts over a time period. Stands for Open High Low Close. Takes the form of a vertical line or bar. At the start (Open) of the time period the price level is indicated by a short horizontal line from the left. As the price rises a vertical line is drawn the top of which is the High point reached during the period. Similarly the line extends down to the low point during the period. At the Close or end of the period a short horizontal line is placed to the right of the vertical bar indicating the price at close. Thus each bar records all salient points through which the price has traveled during the period. See also Candles which show the same data in a similar but some consider more useful manner.
