Table B-1 shows 50 high/low prices from which a high/low Point and Figure chart may be constructed. Because the prices are in the thousands you are going to use a box size of 10. This means that any movement less than 10 is ignored. The chart will be called a 10 x 1 Point and Figure chart (h/l), which means that each X and O is worth 10 points and the reversal required to change columns is one box. The (h/l) tells the person looking at the chart that it is constructed with high/low prices instead of close only.
