A P&F Bear Trap is a Triple Bottom Breakdown that fails: the column of O's breaks the support by only one box and then reverses up into a column of X's. Point and Figure charts plot rising prices as columns of X's and falling prices as columns of O's, ignore time, and add a new column only on a reversal of several boxes, which filters out minor moves. Sellers who shorted the breakdown are trapped, and their covering can fuel a strong rally.
