A P&F Triple Bottom forms when a column of O's reaches a support level that held the two previous O columns. 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. A move one box below the twice-tested low is the Triple Bottom Breakdown, a stronger sell signal than a double bottom because more demand has been exhausted.
