Chartcraft method

Chartcraft method
A method of point & figure charting that dates back to 1947. It has a default boxsize of 0 and a reversal of 3. The boxsize of 0 sets a box value range from $.25 to $2, depending on the price of the issue. The reversal of 3 means that an X column will change to an O column when the price drops at least three boxes below the highest X in the current column. To reverse from Os to Xs, the price must rise three boxes above the lowest O in the current column.
