Class PointAndFigure

Point-and-Figure (P&F) is a time-independent chart filtering out small price movements. It consists of columns of stacked X's and O's, where the X's indicate rising prices while the O's indicate falling prices. Point-and-Figure charts can be used to detect support and resistance levels as well as upward and downward trend lines.
