Rectangles are consolidation patterns that signify indecision between buyers and sellers. They form when price ranges between high and low barriers with alternating highs and lows, and volume tapers off over time. The breakout from the rectangle is reliable, with prices unlikely to return once broken. Target price moves are usually the height of the rectangle. Flags are short, slight price trends within a larger movement that last 1-2 weeks. Rounding bottoms form at market bottoms as investor interest wanes, signaling a reversal from bearish to bullish.
