In technical analysis, certain chart patterns often signal potential trend reversals. The Head and Shoulders pattern, with its peak (head) flanked by two lower peaks (shoulders), typically indicates a shift from bullish to bearish trends. Conversely, the Inverse Head and Shoulders suggests a reversal from bearish to bullish. Double Tops and Double Bottoms are also key, marking resistance or support levels where trends may flip after two failed attempts to break through. The Rounding Bottom or Top reflects a gradual momentum shift, often preceding a reversal. Lastly, Wedge Patterns (rising or falling) can hint at an impending breakout when price consolidation tightens. These formations, when confirmed by volume or other indicators, provide traders with reliable clues for anticipating trend changes.
