A Renko Double Top forms when two columns of white bricks reach about the same high, separated by a pullback. 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 equal highs mark resistance, and the pattern turns bearish when the price falls below the pullback low; a move through the highs instead is a breakout.
