A Renko Bullish Catapult is a breakout above a triple-top resistance that is followed by a pullback and then a second breakout to a new high. Renko charts are built from bricks of a fixed size that ignore time and small price moves: a white brick is added when the price rises by one brick size, a black brick when it falls by one brick size. The pullback that holds above the old resistance confirms it as support, and the new high signals that the uptrend is resuming.
