Broadening Wedge (Expanding Triangle) Chart Pattern: Psychology, Trading Strategies, and Risk Management
1. Introduction to the Broadening Wedge
The Broadening Wedge, also known as the Expanding Triangle, is a chart pattern that reflects increasing volatility.
Unlike symmetrical triangles that narrow over time, the broadening wedge shows diverging trendlines, with progressively wider price swings.
Eventually, price breaks out of the wedge, often in the opposite direction of the last swing.
This breakout can signal either continuation or reversal, depending on the overall trend and volume behavior.
2. Anatomy of the Broadening Wedge
- Trendlines: Two diverging lines, one ascending and one descending.
- Price Swings: Each swing is wider than the previous one.
- Volume Behavior: Volume often increases with volatility, confirming the pattern.
- Breakout: Occurs when price escapes the wedge, typically opposite to the last swing.
3. Market Psychology Behind Broadening Wedges
- Early Phase: Traders are indecisive, leading to volatile swings.
- Middle Phase: Confidence builds, but swings widen as buyers and sellers battle.
- Late Phase: Emotional extremes dominate, creating sharp moves.
- Breakout: One side finally overwhelms the other, leading to continuation or reversal.
This reflects investor psychology:
- Fear and greed amplify volatility.
- Institutions may distribute or accumulate during swings.
- Retail traders misinterpret swings as trend signals.
4. Types of Broadening Wedges
