Markets do not always move in a straight line. During strong trends, price will often pause and begin moving within a tighter range before the next major move develops. Two patterns commonly associated with this type of behaviour are wedges and pennants.
These formations are linked to the idea of price compression, where volatility gradually decreases as buyers and sellers become more balanced over a short period of time. As price tightens into a smaller area, pressure can begin building within the market before a breakout eventually occurs.
Today, we will explain how wedge formations and pennants develop, why compressed price action can lead to stronger moves and how traders estimate potential breakout targets.
What Is Price Compression?
Price compression happens when market movement gradually becomes tighter and more contained.
Instead of making large swings higher and lower, price begins moving within a narrowing structure. This often reflects a temporary balance between buying and selling pressure.
As the range becomes smaller, volatility usually decreases. However, quieter market conditions do not necessarily mean the market has lost momentum. In many cases, it simply means pressure is building before the next larger move develops.
This is why traders often monitor compressed price action closely for potential breakouts.
Understanding Wedge Formations
A wedge formation develops when price moves between two narrowing trendlines.
In some cases, both trendlines move upward. In others, both trendlines move downward. As price continues compressing within the structure, the distance between highs and lows gradually becomes smaller.
Wedges can appear during both continuation and reversal situations, depending on the broader market context. The key feature is the tightening price action itself, which reflects decreasing volatility as the market approaches a potential breakout point.
Understanding Pennants
Pennants are another form of price compression commonly seen after strong directional moves.
After a rapid move higher or lower, the market may begin consolidating within a small triangular structure before continuing in the original direction.
This pause often reflects a temporary balance after a strong expansion in volatility. Many traders view pennants as continuation patterns because breakouts frequently occur in the direction of the previous move. However, confirmation is still important because not every pennant results in continuation.
Why Compression Can Lead to Strong Breakouts
As price compresses into a tighter range, volatility often decreases while momentum gradually builds beneath the surface.
During this phase, traders may begin positioning around the structure while stop losses and pending orders build around the narrowing range. Once price finally breaks outside the structure, activity can increase quickly as new positions enter the market and existing orders are triggered.
This is one reason breakouts from wedges and pennants can sometimes become aggressive once momentum begins expanding again.
Measuring the Expected Move
Some traders estimate breakout targets by measuring the size of the pattern before the breakout occurs.
For example, with a pennant formation, traders may measure the size of the strong move leading into the pattern and project a similar distance from the breakout point.
With wedges, traders often measure the widest part of the structure and use that distance as a guide for a possible target area. These measurements are not exact predictions, but they can help traders build more structured expectations around potential market movement.
The Importance of Confirmation
One common mistake is entering trades before the breakout is fully confirmed.
Compressed markets can sometimes produce false breakouts where price briefly moves outside the structure before quickly returning to the range. Because of this, many traders wait for clearer signs of momentum and stronger market participation before treating the breakout as valid.
Using Compression Alongside Market Structure
Wedge formations and pennants are generally more effective when analysed alongside the broader market environment.
For example, a pennant developing within a strong trend may attract more attention than one forming during sideways conditions. Similarly, a wedge forming near an important support or resistance area may carry more significance than a structure developing in isolation.
Looking at the broader market context can help traders assess whether the breakout has stronger momentum behind it.
Conclusion
Wedge formations and pennants are both based on the idea of price compression, where volatility gradually tightens before a larger move develops.
By understanding how these structures form and how breakouts occur from compressed conditions, traders can develop a clearer view of momentum, volatility and potential market direction.
At Samuel and Co Trading, understanding how volatility and market structure interact forms part of developing a more structured approach to technical analysis and price action.
In trading, periods of quieter price movement can sometimes provide important clues about where momentum may be building before the next larger move begins.
