A Renko Potential Triple Bottom is a column of black bricks that has fallen to a support level already tested twice. 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 pattern is not complete yet: a third turn up would confirm strong support, while a move through it would be a significant breakdown.
