The Broadening Formation: Trading the Megaphone Pattern

Trade-Charts IntelUpdate 2026.03

The Logic of Chaos: What is the Broadening Formation?

The Broadening Formation (often called a 'Megaphone' or 'Inverted Triangle') is a rare and complex chart pattern that occurs when price makes a series of higher highs and lower lows. It represents a period of extreme market confusion and expanding volatility, where neither bulls nor bears are in control, but both are aggressive.

Unlike standard triangles (where volatility contracts), the Broadening Formation shows volatility expanding. This pattern often appears at major market tops or bottoms, signaling that a significant structural shift is imminent due to the total loss of equilibrium.

Identifying the Megaphone Structure

  1. Diverging Trendlines: One rising trendline connects the sequence of higher highs, and one falling trendline connects the sequence of lower lows. 2. At Least 5 Touches: A valid broadening formation should have at least two touches on each trendline and a fifth touch that often signals the final reversal. 3. Increasing Volume: Unlike most patterns, volume tends to increase as the horizontal range grows wider.
💎Institutional Pro Tip

Broadening Execution Checklist

  • Structure: At least 2 higher highs and 2 lower lows

  • Divergence: Trendlines must be moving away from each other

  • Volume: Verify that volume is increasing as price expands

  • Safety: Never trade in the middle of a megaphone

  • Reversal: Target a return to the opposite boundary

  • Stop-Loss: Place 10 pips beyond the previous swing extreme

The Psychological Context: Market Confusion

The Broadening Formation is a 'V-reversal' occurring multiple times in a row. It indicates that traders have lost their sense of 'Fair Value'. Every time price makes a new high, it is immediately rejected into a new low, and vice versa. This 'Megaphone' shape is the ultimate representation of a trend that has entered its final, most speculative phase before collapsing.

Strategy: Trading the 5th Touch or the Breakout

The 5th Touch Reversal: The most common way to trade this pattern is to wait for the 5th touch of the lower or upper boundary and take a reversal trade back toward the center of the formation. This is a high-reward trade because the 'Megaphone' has become so wide by this point.

The Breakout Entry: Alternatively, wait for the price to successfully breakout from one of the diverging trendlines. Because the volatility has already reached an extreme, the resulting breakout is often violent and leads to a massive, long-term trend change.

Frequently Asked Questions

Is this a continuation or reversal pattern?

The Broadening Formation is primarily a reversal pattern. When it occurs at the end of a long uptrend, it is often called a 'Broadening Top' and signals a major bearish rotation. However, always wait for the final structural breakout before committing to a bias.

How do I avoid getting stopped out?

Due to the expanding volatility, the stops must be wider than normal. This pattern is notorious for 'Wick-hunting' traders who use tight stop-losses. Use a multiple of the ATR (Average True Range) to set your risk distance, allowing for the increased volatility within the formation.
