Box Size (Point & Figure Charts)

Box size is the minimum increase or decrease in price needed in a Point & Figure chart to add an X or an O to a column of Xs or Os, respectively. Only price activity equal to or greater than the value of one box is plotted on the chart. The box size is, essentially, the price scale for your Point & Figure chart, and it is customizable because it must be relevant to the market you are evaluating.
