Quick Answer: Chart patterns fall into three families. Continuation patterns — flags, pennants, rectangles and the directional triangles — form during a pause in a move and suggest it resumes in the same direction. Reversal patterns — head and shoulders, double tops and bottoms, wedges, cup and handle — form at the end of a move and suggest the direction changes. Bilateral patterns, chiefly the symmetrical triangle, compress price without implying which way it breaks.
Every one reduces to the same four decisions: what confirms the shape, what triggers the entry, where the invalidation sits, and how far the measured target reaches.
Trading involves significant risk of loss and is not suitable for everyone. This is not financial advice.
Chart Patterns Are Not Candlestick Patterns
The two get confused constantly. A candlestick pattern spans one to three candles — a pin bar, an engulfing pair, an inside bar — and describes what happened inside a few periods. A chart pattern is built from dozens of candles, sometimes hundreds, and describes the shape of a whole consolidation or turn. They work together: the chart pattern says where the level is, the candlestick says whether the break through it carried conviction. Candle anatomy and chart types are in the guide to reading forex charts.
Continuation Patterns
A continuation pattern is a pause, not a decision. Price has moved hard in one direction, participants take profit, the move consolidates, and the pattern is the shape that consolidation takes. Each one below is summarised in the table that follows, with its trigger, invalidation and target.
Flags are the cleanest of them. A sharp directional move — the pole — is followed by a shallow pullback drifting against the trend between two parallel lines. What confirms the pattern is a close out of the flag in the direction of the pole, and what invalidates it is price working back through the far side of the flag instead. The target adds the pole height to the break, which makes the pole the measurement that matters: a flag with an unclear starting point has no target.
Pennants are the same idea in a tighter shape. Rather than drifting against the trend, the pause converges into a small symmetrical triangle. Pole, trigger and target work identically, but the smaller shape means a closer stop and a faster invalidation — useful when it works, and expensive when the shape is only noise.
Ascending and descending triangles are the directional members of the family. An ascending triangle has a flat ceiling with rising lows: buyers keep paying more while sellers defend one price, which usually resolves upward. A descending triangle inverts it, with a flat floor and falling highs. The flat side is the one that matters, because it is the level being defended, and the height of the triangle at its widest point is what gets projected from the break.
Rectangles are ranges everyone can see — two horizontal boundaries, price bouncing between them, no bias inside the shape. They tend to break in the direction of the trend that preceded them, but until they do a rectangle is a range rather than a signal.
| Pattern | Shape | Entry trigger | Stop | Measured target |
|---|---|---|---|---|
| Bull/bear flag | Sharp pole, then a shallow counter-trend channel | Close beyond the flag boundary | Beyond the far side of the flag | Pole height added to the break |
| Pennant | Pole, then a small converging triangle | Close beyond the pennant | Beyond the opposite converging line | Pole height added to the break |
| Ascending triangle | Flat ceiling, rising lows | Close above the ceiling | Below the last higher low | Widest height added to the break |
| Descending triangle | Flat floor, falling highs | Close below the floor | Above the last lower high | Widest height subtracted from the break |
| Rectangle | Two horizontal boundaries | Close beyond either boundary | Back inside the range | Range height projected from the break |
| Symmetrical triangle | Both boundaries converging | Close beyond either line | Back inside the triangle | Widest height added to the break |
Reversal Patterns
Reversal patterns mark the point where the side in control runs out of participants. They take longer to form than continuation patterns and they fail differently: a failed reversal often resumes the original trend violently, because everyone positioned for the turn has to exit at once.
Head and shoulders is the most watched formation in technical analysis. Three peaks, the middle one highest, with a neckline drawn under the two troughs. The neckline is the whole pattern — above it the shape is just three peaks, below it the structure of higher highs is broken. The inverse version mirrors it at the bottom of a downtrend and deserves a full treatment, which it has in the inverse head and shoulders guide.
Double tops and double bottoms are the simplest reversals to identify and the easiest to misread. Two peaks at roughly the same level, separated by a trough that becomes the neckline. Price failing twice at one price says sellers are defending it; it does not say they will win. Triple tops and bottoms work the same way with one more test.
Wedges slope, which is what separates them from triangles. In a rising wedge both boundaries rise with the lower one steeper, so the range narrows while price grinds higher on shrinking momentum — a bearish signal even inside an uptrend. A falling wedge inverts it and reads bullish. Because the shape converges, the measurement comes from the widest part back at the wedge’s start rather than from where it broke.
Cup and handle is the slowest of the group: a rounded U-shaped base built over weeks or months, a recovery to the old high, then one shallow pullback — the handle — before the break. On four-hour and daily forex charts these are genuinely rare, and a two-day cup is noise wearing the name.
| Pattern | Shape | Entry trigger | Stop | Measured target |
|---|---|---|---|---|
| Head and shoulders | Three peaks, middle highest, neckline under the troughs | Close below the neckline | Above the right shoulder | Head-to-neckline depth subtracted from the neckline |
| Inverse head and shoulders | The same shape inverted at a low | Close above the neckline | Below the right shoulder | Depth added to the neckline |
| Double top | Two peaks at one level | Close below the neckline | Above the second peak | Pattern height subtracted from the neckline |
| Double bottom | Two troughs at one level | Close above the neckline | Below the second trough | Pattern height added to the neckline |
| Rising wedge | Both lines rising, converging | Close below the lower line | Above the last high inside | Widest height subtracted from the break |
| Falling wedge | Both lines falling, converging | Close above the upper line | Below the last low inside | Widest height added to the break |
| Cup and handle | Rounded base, then a shallow pullback | Close above the handle high | Below the handle low | Cup depth added to the break |
Measuring a Target: a Worked Example
Take a head-and-shoulders top on EUR/USD: left shoulder at 1.0960, head at 1.1050, right shoulder at 1.0975, and a neckline at 1.0900. The depth from head to neckline is 150 pips, so the measured target is 1.0900 − 0.0150 = 1.0750.
That is the easy part. The arithmetic that decides whether the trade is worth taking is the entry, and two conventional entries produce different trades:
- Entry on the break at 1.0890, stop above the right shoulder at 1.0985: 95 pips of risk against 140 of reward, 1.47 R
- Entry on a retest of the neckline at 1.0900, same stop: 85 pips of risk against 150 of reward, 1.76 R
The measured move is a convention rather than a forecast, and even the convention is not fixed. On a bull flag with a 120-pip pole, a flag low at 1.0880 and a breakout at 1.0905, projecting the pole from the flag low gives a target of 1.1000 while projecting it from the breakout gives 1.1025 — a 25-pip difference produced entirely by which textbook you read. Pick one and use it consistently, because inconsistency makes your own results impossible to compare.
The number that matters more is whether the target justifies the stop at all. A double top with peaks at 1.1000 and a neckline at 1.0920 gives a height of 80 pips and a target of 1.0840. Enter at 1.0915 with a stop above the peak at 1.1008 and the trade is 93 pips of risk against 75 of reward — 0.81 R, before costs. The pattern can be textbook-perfect and the trade still not worth placing, which is a check to run before entry rather than after. The risk-reward guide covers the ratio in full.
Why Patterns Fail
- They are drawn in hindsight. Anyone can find a flag on last week’s chart. Marking one before the break is a different skill, and the test is whether you wrote the levels down in advance.
- Everyone sees the same shape. A well-formed top puts thousands of stops in the same place just beyond the right shoulder. Those stops are liquidity, and price frequently reaches for them before doing what the pattern suggested.
- The timeframe does not match the trade. A pattern on the 5-minute chart resolves within a session and is dominated by spread and noise. Most of these formations are designed for four-hour and daily charts — see the timeframes guide.
- A scheduled release overrides the shape. No formation survives an unexpected CPI print — pattern analysis describes positioning, not new information.
- The measured move is a rule of thumb. It comes from the pattern’s own geometry, not from any property of the market, and it is not the same thing as a probable destination.
You will find published hit rates for each of these formations. They vary widely between studies depending on the instrument, the timeframe, the sample period and how strictly the pattern was defined, so this guide does not repeat any of them. If you want a number, the useful one is your own, recorded from your own trades at your own definitions.
Patterns Need Support and Resistance to Mean Anything
A pattern in empty space is just a shape. What gives a formation weight is where it sits relative to levels the market has already respected, and the difference is easy to test on your own charts.
A double top whose neckline coincides with a level that held three times last month is a different proposition from one floating mid-range: the break clears two obstacles at once, and the invalidation is defined by something other than your own drawing. A bull flag forming just under a daily resistance level is fighting the structure above it, whatever the flag suggests alone. Horizontal levels are covered in the support and resistance guide, diagonal ones in the trend lines guide, and the wider reading approach in the price action guide.
The practical rule: mark your levels first, then look for patterns. Doing it the other way round produces formations that fit the levels because you fitted them.
Risk Warning
Chart patterns describe past price, not future price. A formation identified correctly can still fail, and a measured target is a projection produced by geometry rather than a price the market owes you. Size every position from the stop distance rather than the target, assume any pattern can invalidate on the next candle, and never place a trade whose loss you have not calculated in advance.
Frequently Asked Questions
What are the three types of forex chart patterns?
Continuation patterns, which suggest a paused move resumes; reversal patterns, which suggest a move is ending; and bilateral patterns such as the symmetrical triangle, which compress price without indicating direction.
What is the difference between a chart pattern and a candlestick pattern?
Scale. A candlestick pattern spans one to three candles and describes short-term behaviour; a chart pattern is built from dozens of candles and describes the shape of an entire consolidation or reversal.
How do you calculate a chart pattern target?
Measure the pattern’s height at its widest point and project it from the breakout. On a head-and-shoulders top that means the head-to-neckline depth subtracted from the neckline; on a flag, the pole height added to the break. It is a convention, so apply it the same way every time.
Which chart patterns are most reliable?
Reliability figures vary too much between studies to quote responsibly. What holds across all of them is that patterns on higher timeframes, at levels that already mattered, with a clearly defined invalidation, are more workable than the same shapes drawn mid-range on a 5-minute chart.
Where does the stop go on a chart pattern trade?
Beyond the structure that would invalidate the shape: past the right shoulder on a head-and-shoulders top, past the second peak on a double top, on the far side of a flag. If that distance makes the trade unattractive against the measured target, the correct response is to skip the trade rather than to tighten the stop.
Do chart patterns work on all timeframes?
The shapes appear on every timeframe, but below the one-hour chart the spread and ordinary noise become a large share of the pattern’s height, which makes the measured targets hard to reach in practice.
Key Takeaways
- Three families: continuation (flags, pennants, triangles, rectangles), reversal (head and shoulders, double tops and bottoms, wedges, cup and handle), and bilateral
- Every pattern reduces to four decisions: confirmation, entry trigger, invalidation, measured target
- The measured move is geometry, not a forecast — and even the convention differs by 25 pips on the flag example above
- Check the reward against the stop before entry: the double top example gave 0.81 R despite a textbook shape
- Patterns mean more at levels that already mattered — mark levels first, patterns second
- Below the one-hour chart, spread and noise take too large a share of the pattern’s height
