Broadening patterns, also called megaphone or expanding patterns, form when price creates progressively higher highs and lower lows, diverging rather than converging. These patterns reflect increasing volatility and disagreement between buyers and sellers, often appearing during periods of uncertainty or at major market turning points. Broadening patterns are among the most challenging formations to trade because they lack the contracting structure of typical chart patterns.
Price swings expand with each successive high and low, creating a widening range. The pattern resembles an inverted triangle or megaphone shape. Broadening tops form at the end of uptrends and are bearish reversal patterns. Broadening bottoms form at the end of downtrends and are bullish reversal patterns. The pattern reflects increasing emotional trading and indecision. Volume typically increases as the pattern develops, confirming rising volatility. Five swing points (three on one side, two on the other) define a complete broadening formation.
Trade the reversals at the pattern boundaries — buy at the lower trendline and sell at the upper trendline. Enter after the fifth swing completes, anticipating that the pattern is now likely to resolve. Breakout entries when price closes decisively beyond one of the expanding boundaries. Fade extreme moves back toward the pattern's midline when boundary touches coincide with divergence.
Target the opposing boundary when trading bounces within the pattern. Stop just beyond the boundary that triggered the entry. Exit boundary-trading positions if the breakout occurs with strong volume against your direction. Pattern resolution target: the widest point of the pattern projected from the breakout.

Broadening patterns are best left to experienced traders because the expanding volatility makes risk management difficult. The most reliable trade is a fade of the fifth swing point, as the pattern tends to resolve after five touches. If you are not confident in the pattern count, stand aside until a clear breakout occurs with strong volume confirmation.
The head and shoulders is one of the most reliable reversal patterns in technical analysis. It consists of three peaks — a higher central peak (the head) flanked by two lower peaks (the shoulders) — connected by a neckline drawn across the reaction lows. A break below the neckline confirms the reversal, with the measured target equal to the distance from the head to the neckline projected downward from the breakout point.
The cup and handle is a bullish continuation pattern resembling a teacup when viewed from the side. The cup forms as a rounded bottom with the left and right rims at approximately the same level, followed by a small downward-drifting consolidation (the handle). A breakout above the handle's resistance triggers the measured move, calculated from the bottom of the cup to the rim.
Double tops and double bottoms are two-touch reversal patterns that form when price tests the same level twice and fails to break through. A double top signals bearish reversal after an uptrend, while a double bottom signals bullish reversal after a downtrend. The pattern is confirmed when price breaks the support or resistance level formed between the two peaks or troughs.
The rounding bottom (also known as a saucer pattern) is a long-term bullish reversal formation characterised by a gradual, U-shaped transition from a downtrend to an uptrend. The pattern reflects a slow shift in sentiment from bearish to neutral to bullish, typically forming over weeks or months. A breakout above the pattern's resistance (the left rim level) confirms the reversal.
