Pennant Pattern Trading: How to Spot and Trade Breakouts
In this article
A pennant pattern is a short-term continuation chart pattern characterised by a sharp initial impulse move, known as the flagpole, followed by brief consolidation within converging trendlines. A breakout in the direction of the preceding trend may signal continuation, with increased volume providing additional confirmation.
A pennant pattern is a short-term continuation chart pattern that forms after a sharp price move, followed by a brief period of consolidation within converging trendlines.
Jump in while price is still consolidating and you can end up with an early entry or a false breakout. Knowing how a pennant pattern develops can help you wait for clearer confirmation, read volume behaviour and manage risk more effectively.
Quick Takeaways
- Pennants are short-term continuation patterns that represent a temporary pause within an existing trend.
- A typical pennant begins with a sharp impulse move, known as the flagpole, followed by a small consolidation characterised by lower highs and higher lows.
- Volume often contracts during consolidation and may increase when price breaks out of the pattern.
- Key risks include false breakouts, slippage, wider spreads during volatile periods and overnight financing costs when CFD positions remain open across trading sessions.
What Is a Pennant Pattern?
In classical technical analysis, chart patterns provide a visual framework for analysing changes in price behaviour, market participation and supply and demand over time.
A pennant is generally treated as a continuation pattern. It forms when the market pauses after a sharp move, before potentially picking the prevailing trend back up.
The pattern has two main components:
The Flagpole: A sharp and relatively rapid price advance or decline that establishes the directional move preceding the consolidation.
The Pennant: A compact consolidation structure formed by converging trendlines. Price typically produces lower highs and higher lows as the trading range narrows towards the apex. Trading volume may also decline as the pattern develops.
Pennants should be distinguished from similar chart structures. A flag typically consolidates within roughly parallel trendlines, whereas a pennant contracts between converging trendlines.
Pennants are also generally treated as relatively short-term structures. Classical technical-analysis descriptions commonly associate flags and pennants with brief consolidations following a sharp directional move, although the exact duration varies by market and timeframe. Larger converging formations that develop over longer periods may be better classified as symmetrical triangles.

Bullish vs Bearish Pennants
Pennants can develop during both rising and falling markets. The direction of the move immediately preceding the consolidation provides the context for distinguishing a bullish pennant from a bearish one.
Bullish Pennant Pattern
A bullish pennant develops after a strong upward price move. The initial rally forms the flagpole before price enters a brief consolidation characterised by lower highs and higher lows.
Trading activity may decline as the consolidation develops. A break above the upper descending trendline can indicate a potential continuation of the preceding uptrend, particularly when the breakout is accompanied by stronger trading volume.
However, a breakout does not guarantee continuation, and price can move back inside the pattern after initially crossing the trendline.
Bearish Pennant Pattern
A bearish pennant develops after a sharp downward price move. The initial decline forms the flagpole before price begins consolidating within a narrowing range.
As the upper and lower trendlines converge, a break below the lower ascending trendline can indicate that downward momentum is resuming. An increase in trading volume may provide additional confirmation, although false breakdowns remain possible.
Feature | Bullish Pennant | Bearish Pennant |
|---|---|---|
Prior Trend | Strong uptrend | Strong downtrend |
Flagpole Direction | Sharp upward move | Sharp downward move |
Consolidation Shape | Converging lower highs and higher lows | Converging lower highs and higher lows |
Volume Profile | Often contracts during consolidation and may expand on an upside breakout | Often contracts during consolidation and may expand on a downside breakdown |
Theoretical Target | Projected upwards from the breakout | Projected downwards from the breakdown |
Calculating Theoretical Targets and Planning Trade Entries
Technical analysts may use the length of the initial flagpole to estimate a theoretical price target following a breakout. This is a measured-move technique rather than a guaranteed price objective.
Target Calculation Formula
A common approach is to:
- Measure the vertical distance between the beginning and end of the flagpole.
- Project that distance from the breakout level in the direction of the prevailing trend.
For a bullish pennant:
Flagpole Height = Peak Price − Base Price
Theoretical Target = Breakout Price + Flagpole Height
For example, suppose an asset rises from $100 to $150 before consolidating into a pennant. The flagpole measures $50.
If price subsequently breaks above the pennant at $145:
$145 + $50 = $195
The theoretical target would therefore be $195.
This calculation provides a reference point for analysing the potential size of a continuation move. It does not mean that price will necessarily reach the projected level.
Trade Entry and Order Management
Traders may approach pennant breakouts in different ways depending on their confirmation criteria and risk tolerance.
Breakout Entry: Some traders wait for price to close outside the relevant pennant trendline before considering an entry. Increased volume may provide additional evidence that market participation has strengthened.
Retest Entry: A trader waits to see whether price returns towards the broken trendline after the initial breakout. The former resistance level may act as support after an upside breakout, while former support may act as resistance following a downside break.
Risk management is usually based on the point at which the original setup would no longer make sense. Depending on the strategy, a stop-loss may be placed beyond the opposite side of the consolidation or another predefined invalidation level.
A move back inside the pennant after a breakout can indicate that the initial break has failed, although the precise invalidation rule depends on the trading methodology being used.
Risk Management and Execution Realities in CFD Trading
Trading pennant breakouts through leveraged Contracts for Difference (CFDs) introduces execution and financing risks beyond the chart pattern itself.
Breakouts can be tricky to execute because prices can move fast as orders hit the market. You may get a different price from the one you expected, especially when liquidity thins out or volatility picks up.
For this reason, identifying the pattern is only one part of the process. Position sizing, order type, spread conditions, slippage and predetermined invalidation levels can all affect the eventual outcome.
Key execution risks include:
False Breakouts: Price may move beyond a pennant trendline and then reverse back into the consolidation range. Waiting for a closing-price confirmation or considering other supporting evidence may help filter some false signals, but it cannot eliminate them.
Slippage and Spread Expansion: Volatile market conditions, economic announcements or sudden changes in liquidity can cause spreads to widen. Market and stop orders may consequently be executed at a different price from the level requested.
Overnight Financing Costs: CFD positions held overnight may incur financing charges. If a position remains open for several sessions, these costs can accumulate and affect the overall result. The exact charge depends on the provider, instrument and position.
Leverage Risk: Leverage magnifies both profits and losses because traders gain exposure to a larger position than the initial margin they provide. For UK retail clients of FCA-authorised firms, FCA rules impose leverage limits ranging from 30:1 to 2:1 depending on the underlying asset. They also require account-level margin close-out when net equity falls below 50% of the required margin and provide negative balance protection. Similar CFD product-intervention protections apply within the EU under the relevant national measures. Providers outside these regimes may not offer the same safeguards, so it's worth checking a firm's authorisation on the FCA Register before you open an account.
Retail CFD Losses: CFDs carry a high risk of losing money rapidly due to leverage. Rather than applying a universal industry loss rate, traders should check the current risk warning published by the individual CFD provider. FCA rules require firms to disclose the percentage of their retail client accounts that lost money, calculated using the firm's own client data and updated every three months.
Conclusion
The pennant pattern provides a framework for identifying short-term consolidation after a strong directional price move. Traders typically assess the preceding flagpole, the contraction between converging trendlines, changes in trading volume and the eventual breakout when evaluating the setup.
Measured-move targets can provide a reference point, but neither the pattern nor its projected target guarantees that the prevailing trend will continue. False breakouts and changing market conditions can invalidate the setup.

CFDs are leveraged products and can result in rapid losses. Technical patterns should therefore be treated as analytical tools rather than predictions of future market movement.
FAQ
What Is the Difference Between a Pennant Pattern and a Flag Pattern?
Both are short-term continuation patterns that form after a sharp directional move, known as the flagpole. The main difference is the shape of the consolidation. A flag typically develops between roughly parallel trendlines, creating a channel, whereas a pennant contracts between converging trendlines to form a small symmetrical triangle.
Is a Pennant Pattern Bullish or Bearish?
A pennant pattern can be either bullish or bearish, depending on the direction of the preceding trend. A bullish pennant forms after a sharp upward move and may break out higher, while a bearish pennant develops after a steep decline and may break down lower.
How Do You Calculate the Price Target for a Pennant Pattern?
A theoretical price target can be estimated by measuring the vertical height of the initial flagpole. For a bullish pennant, this distance is added to the breakout price. For a bearish pennant, it is subtracted from the breakdown price. The resulting level is a theoretical target rather than a guaranteed outcome.
What Causes a False Breakout in a Pennant Pattern?
A false breakout occurs when price moves beyond a pennant trendline but fails to maintain momentum and subsequently returns to the consolidation range. Low trading volume or weak momentum may accompany some false breakouts, but neither factor determines the outcome on its own. Waiting for a candlestick to close outside the pattern can provide additional confirmation, although it cannot eliminate false signals.
How Long Does a Pennant Pattern Take to Form?
Pennants are generally short-term formations, but there is no fixed duration that applies across all markets and timeframes. On daily charts, they may develop over several sessions or a few weeks, while intraday pennants can form much more quickly. If consolidation continues for an extended period, the structure may be better classified as a broader symmetrical triangle.
