A P&F Potential Triple Bottom is a column of O's that has fallen to within one box of 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. One more box down would complete a Triple Bottom Breakdown, one of the strongest Point and Figure sell signals.
