Pennant Pattern in Forex: How It Works and How to Read It

A pennant is a short-term continuation pattern. It forms after a sharp price move, pauses in a small triangle shape, then often continues in the same direction as the move that came before it. In forex, traders watch pennants to judge whether a strong trend is likely to keep going after a brief pause.

Key takeaways

• A pennant is a continuation pattern: a sharp move (the flagpole), a short pause in a small converging triangle (the pennant), then a breakout in the trend direction.

• A bullish pennant points up; a bearish pennant (sometimes called a reverse or downward pennant) points down. They are the same shape, mirrored.

• The classic price target projects the flagpole height from the breakout point.

• The pattern is not a sure thing. In the largest published study of US stocks, pennants failed to move more than 5% after the breakout about 54% of the time, and reached their measured target only about a third of the time.

• Forex has no central volume data, so the common “confirm with volume” rule is weaker in currency markets than in stocks. 

What is a pennant pattern?

A pennant has three parts.

First comes the flagpole. This is a steep, fast price move in one direction, usually driven by a clear catalyst such as an interest rate decision or a major economic release. The move is sharp and covers a lot of ground in a short time.

Second comes the pennant itself. After the sharp move, price pauses and trades in a narrowing range. The highs get lower, and the lows get higher, so the price action squeezes into a small triangle. Two trendlines drawn along those highs and lows converge toward each other. This part usually lasts a short time, typically up to three weeks on a daily chart.

Third comes the breakout. Price leaves the triangle, and in a continuation pennant, it leaves in the same direction as the flagpole.

The logic is that a strong move runs into a pause as some traders take profit and the market catches its breath. If the original pressure is still there, price breaks out and continues. The pennant is the visible shape of that pause.

Bullish pennant vs bearish pennant

The two versions are mirror images.

A bullish pennant forms during an uptrend. The flagpole points up, price pauses in the triangle, and the expected breakout is upward, continuing the rise.

A bearish pennant forms during a downtrend. The flagpole points down, price pauses, and the expected breakout is downward, continuing the fall. You may see this called a “reverse pennant” or a “downward pennant.” These are not separate patterns. They are simply the bearish version, named differently on different sites. If a pennant is pointing down in a downtrend, it is a bearish pennant.

The direction of the flagpole tells you which one you are looking at. The triangle shape is identical in both.

How is a pennant different from a flag, a triangle, and a wedge?

Pennants are easy to confuse with other patterns. The differences are specific, and getting them right matters because each pattern behaves differently.

A flag also follows a flagpole, but its boundary lines are roughly parallel, forming a small tilted rectangle or channel that leans against the trend. A pennant’s lines converge. Parallel means flag; converging means pennant.

A symmetrical triangle has converging lines like a pennant, but it does not need a flagpole in front of it, and it usually takes much longer to form, often weeks to months. The rule of thumb from chart-pattern researcher Thomas Bulkowski is duration: a converging triangle that forms in three weeks or less, right after a sharp move, is a pennant. One that takes longer, without that sharp move ahead of it, is better classified as a triangle.

A wedge also has converging lines, but the whole shape clearly slopes up or down, and it can signal either continuation or reversal. A pennant sits roughly level and signals continuation.

How to read a pennant: entry, target, and invalidation

This section explains how technicians approach the pattern. It is educational. It is not a recommendation to trade in any particular way.

The breakout

The pattern is generally considered active only once price closes outside the triangle. Many technicians wait for a completed candle beyond the trendline rather than reacting to a brief intrabar poke, because false breaks are common inside a tight pattern. Some also watch for a return to the broken trendline, called a throwback in an uptrend or a pullback in a downtrend, before deciding the move is genuine.

The measured move (price target)

The classic method for a target uses the flagpole height. You measure the size of the flagpole, then project that distance from the breakout point in the direction of the breakout.

Here is a worked example on EUR/USD.

• Price rallies from 1.0800 to 1.0900. The flagpole is 100 pips.

• Price then pauses and forms a pennant between about 1.0870 and 1.0890.

• Price breaks out above 1.0890.

• Target = breakout point + flagpole height = 1.0890 + 0.0100 = 1.0990.

The same method works in reverse for a bearish pennant: measure the down flagpole and project it down from the breakout point.

Where the pattern breaks down

A pennant is generally treated as void or unreliable when:

• It lasts too long. Past about three weeks, the shape is no longer a pennant. It has become a triangle or a wedge, and the “coiled spring after a sharp move” logic weakens.

• Price retraces too far. If price gives back more than roughly half of the flagpole during the pause, the energy behind the original move has faded, and the setup loses its meaning.

• The breakout goes the wrong way. A continuation pennant that breaks against the prior trend has failed as a continuation signal.

Technical analysis literature usually discusses a protective stop placed just beyond the opposite trendline: below the pennant’s low for a bullish breakout, above its high for a bearish one. A tighter stop risks less per trade but is more likely to be triggered by the normal noise inside the pattern.

The point most forex guides get wrong: volume

Almost every explanation of the pennant repeats the same rule: volume should shrink during the pause and expand on the breakout. In stocks, that rule is sound, because stock exchanges report real, centralised volume.

Spot forex is different. It is a decentralised market traded across many banks and venues with no central exchange, so there is no single, true volume figure. What trading platforms such as MetaTrader show is tick volume: the number of price updates in a given period. Tick volume is only a proxy for activity. It changes from one broker to another depending on their price feed, and it is not the same as the actual money traded.

For a forex trader, this has a direct consequence. The “confirm the breakout with a volume spike” rule is weaker and less dependable in currency markets than in stocks. You can still use tick volume as a rough guide, but only within the same broker feed, and with caution.

Forex technicians tend to lean more on price itself: the decisiveness of the breakout candle, the location of the pattern, and the level of activity in the current trading session. The London and New York overlap, for example, is the most active window for the major pairs.

This distinction is the main reason a forex-specific pennant guide should not simply copy the stock-market version.

How reliable is the pennant pattern?

Here is where honesty separates a useful page from a sales pitch. Many sources describe the pennant as high-probability. The most cited body of evidence does not support that.

Thomas Bulkowski, in the Encyclopedia of Chart Patterns (2nd edition, Wiley, 2005), measured pennants across a large sample of US stocks. His figures, updated on his research site in 2020, include:

• A break-even failure rate of about 54% for both bullish and bearish pennants. In his method, that is the share of pennants that failed to move more than 5% after the breakout.

• An average rise of about 7% after an upward breakout, and an average decline of about 6% after a downward one.

• The measured-move target reached only about 35% of the time for upward breakouts and 32% for downward ones.

• Breakouts that resolved upward occurred about 57% of the time.

Bulkowski also notes that the pennant marks the true midpoint of a move only around 30% of the time, which is a useful check on the “half-mast” idea.

Two caveats matter. First, this data is drawn mainly from US stocks, not forex, and it uses an idealised measurement. It should be read as a guide to how the pattern behaves in general, not as a forex-specific figure.

Second, researchers disagree. Some analysts argue the pennant is genuinely weak and treat that 54% failure rate as a reason to be sceptical of it. Others treat it as a reasonable continuation signal when it appears after a strong, clean move. Both views come from the same numbers. The sensible reading is that a pennant tilts the odds slightly, at best, and is never a guarantee.

Pennants in stocks

The pennant is not unique to forex, and the queries around it span several markets.

In stocks, the pattern works as the textbooks describe, because exchange volume is real and reliable. The classic signature of heavy volume on the flagpole, light volume in the pause, and rising volume on the breakout can be read directly. Bulkowski’s statistics above are drawn from this market.

Why patterns are only part of the job

Forex is the largest financial market in the world. According to the Bank for International Settlements 2025 Triennial Survey, trading in foreign exchange markets reached $9.6 trillion per day in April 2025, up 28% from 2022, with the US dollar on one side of 89% of all trades. In a market that size and that fast, no single chart shape decides an outcome.

The risk is real and well documented. European regulator ESMA found that 74% to 89% of retail investor accounts lose money trading CFDs, based on analysis across EU jurisdictions. A pattern like the pennant can help structure a decision and works best as one input among several: the trend, the location of the pattern, the strength of the breakout, and a clear plan for what happens if the setup fails.

If you want to build from here, start with the chart patterns hub for how continuation and reversal patterns fit together, then compare the pennant with the closely related flag pattern and the symmetrical triangle.

Frequently asked questions

What is a pennant pattern in forex?

It is a short-term continuation pattern. A sharp price move (the flagpole) is followed by a brief pause that squeezes into a small converging triangle (the pennant), after which price often breaks out in the same direction as the original move.

What is the difference between a bullish and a bearish pennant?

A bullish pennant forms in an uptrend and is expected to break upward. A bearish pennant, also called a reverse or downward pennant, forms in a downtrend and is expected to break downward. The shape is the same; only the direction differs.

How do you calculate a pennant price target?

Measure the height of the flagpole, then project that same distance from the breakout point in the breakout direction. For a 100-pip flagpole with a breakout at 1.0890, the target is 1.0990. Studies suggest this full target is reached only about a third of the time, so treat it as a reference.

Is the pennant pattern reliable?

It is not a guarantee. The largest published study, on US stocks, found a break-even failure rate near 54% and the measured target reached only about a third of the time. It can tilt the odds slightly after a strong move, but it should be used with risk controls, not trusted blindly.

Why is volume less useful for pennants in forex?

Spot forex has no central exchange, so there is no true market-wide volume. Platforms show tick volume, which counts price updates and only estimates real activity. That makes the usual “confirm the breakout with volume” rule weaker in forex than in stocks.

How long does a pennant last?

On a daily chart, up to about three weeks. If a converging triangle takes longer than that, it is usually better classified as a symmetrical triangle or a wedge rather than a pennant.

Conclusion

The pennant is a clear, useful way to read a pause inside a strong trend, and it is worth knowing well. But its value comes from understanding its limits as much as its shape. The data says it fails more often than most guides admit; its price target is a reference rather than a forecast, and in forex the volume confirmation that stock traders rely on is only an estimate.

Read the pattern for what it is: a snapshot of a market catching its breath, with a slight lean toward the trend continuing. The traders who use it best are the ones who already know what they will do when it does not work.
