A P&F Bearish Catapult is a Triple Bottom Breakdown followed by a rebound in a column of X's and then a Double Bottom Breakdown. 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. The pattern combines two sell signals: the rebound fails below the old support, and the new O column confirms that the breakdown is real and the downtrend is resuming.
