Stock chart patterns are recognizable shapes that price traces on a chart as buyers and sellers push against each other. Traders sort them into two broad groups. Continuation patterns, such as flags, pennants, wedges, triangles and the cup and handle, mark a pause before the existing trend resumes. Reversal patterns, such as head and shoulders, double tops and bottoms, and triple tops and bottoms, mark the point where a trend runs out of energy and turns. Almost all of them are built from the same raw materials: trendlines, support and resistance levels, and changes in volume. If you can draw those accurately, you can read nearly any pattern a stock chart produces. The same is true of forex, futures or crypto charts.

Trendlines: the building blocks of price patterns

A trendline is a straight line connecting a series of rising lows or falling highs. It gives a visual boundary to the trend and marks areas where price has repeatedly found support or met resistance.

• Uptrend: price makes higher highs and higher lows. An up trendline connects at least two of the rising lows and acts as support beneath price.
• Downtrend: price makes lower highs and lower lows. A down trendline connects at least two of the falling highs and acts as resistance above price.
• Consolidation (sideways market): price oscillates between two roughly parallel lines, often horizontal, with neither side in control.

Two touches are enough to draw a line, but chartists generally treat a line with three or more touches as more valid, because each additional test shows that other market participants are reacting to the same level.

Which part of the bar to use

There is no single correct method for anchoring a trendline. The three common approaches are:

1. Wicks (highs and lows): captures the full range of each bar, but a single spike on news can pull the line out of position.
2. Candle bodies: the body spans the open and the close and excludes the thin wicks. Many traders prefer this because it filters out outliers.
3. Closing prices: popular on longer-term charts because the close is the last regular-session trade and reflects where the market settled.

Whichever method you choose, apply it consistently across the chart. A line drawn through wicks on one swing and through bodies on the next will give false breakouts.

Continuation, reversal and bilateral patterns

While a pattern is still forming, you cannot know whether the trend will continue or reverse. The classification only becomes clear once price breaks out of the zone. This is why many technical analysts default to assuming the existing trend remains in force until a reversal is confirmed.

Continuation patterns represent a temporary interruption. In an uptrend, buyers pause to catch their breath; in a downtrend, sellers ease off for a while. If price then breaks out in the direction of the prior trend, the pattern is classed as a continuation.

Reversal patterns form when the dominant side has exhausted itself. The trend stalls, pressure between buyers and sellers evens out, and eventually the other side takes over. Reversals at market tops are called distribution patterns: the instrument is being sold more aggressively than it is bought. Reversals at bottoms are called accumulation patterns: the instrument is being bought more actively than it is sold.

Some guides add a third group, bilateral patterns, for shapes that can break either way. Classifications differ: some traders place ascending, descending and symmetrical triangles in the bilateral group, while others reserve it for the symmetrical triangle alone.

A general rule applies to both main groups: the longer a pattern takes to develop, and the wider the price swings inside it, the more significant the move traders expect once price breaks out.

Continuation patterns

Flags

A flag is drawn with two parallel trendlines, forming a small rectangle or channel. It follows a sharp move, known as the flagpole, and slopes against that move.

• In an uptrend, a bullish flag typically slopes downward, a controlled pullback before the next leg up.
• In a downtrend, a bearish flag typically slopes upward, a weak bounce before selling resumes.
• A flag can also be horizontal.

Pennants

A pennant also follows a sharp flagpole move, but its two trendlines converge rather than run parallel. One line slopes down and the other slopes up, so the consolidation narrows into a small symmetrical point. A bullish pennant sits on top of an upward flagpole; a bearish pennant hangs below a downward one.

The sequence is always flagpole first, then consolidation. The main visual difference from a flag is the shape of the pause: parallel lines for a flag, converging lines for a pennant.

Wedges

A wedge is drawn with two converging trendlines that slope in the same direction, either both up or both down. That shared slope is what separates a wedge from a pennant or symmetrical triangle, where the lines point in opposite directions.

As continuation patterns:

• A falling wedge (angled down) represents a pause within an uptrend.
• A rising wedge (angled up) represents a temporary interruption within a downtrend.

Wedges can also act as reversal patterns depending on context. A rising wedge that forms after an extended uptrend, for example, is often read as a sign of weakening buying pressure.

Triangles

The three standard triangles are ascending, descending and symmetrical, and they can take anywhere from a couple of weeks to several months to form on a daily chart.

Ascending triangle. A flat, horizontal resistance line on top and a rising support line underneath. Each pullback stops at a higher low, showing buyers stepping in earlier, while sellers keep defending the same ceiling. The pattern is considered bullish, and a breakout above the horizontal resistance is the usual entry signal.

Descending triangle. The mirror image: a horizontal support line on the bottom and a falling upper trendline. Each rally peaks at a lower high, which suggests demand is fading, and the pattern points toward a breakdown through support.

Symmetrical triangle. Two converging trendlines with roughly equal slopes, one falling from the highs and one rising from the lows. On its own it signals only that a breakout is likely, not which direction it will take.

Cup and handle

The cup and handle is a bullish continuation pattern in which an uptrend pauses, forms a rounded base and then resumes once the pattern is confirmed.

• The cup is a U shape rather than a sharp V. The rounded bottom indicates a gradual shift from selling to buying rather than a single sharp rebound. Ideally the highs on either side of the cup are roughly equal, though that is not strictly required.
• The handle forms on the right side as a short, shallow pullback that resembles a small flag or pennant.

When price breaks above the top of the handle, the stock may move to new highs and resume its prior uptrend.

Reversal patterns

Head and shoulders

The head and shoulders appears as three pushes: an initial peak (the left shoulder), a second and larger peak (the head), and a third peak roughly matching the first (the right shoulder). A line drawn through the troughs between those peaks is called the neckline. It can be horizontal or slightly sloped.

• A head and shoulders top forms after an uptrend. A close below the neckline signals a possible reversal into a downtrend.
• A head and shoulders bottom, or inverse head and shoulders, forms after a downtrend. It is the same structure flipped upside down, and a close above the neckline signals a possible reversal to the upside.

The right shoulder matters because it shows the trend failing to make a new extreme. In a top, buyers could not push price back to the height of the head, which is the first concrete evidence that their control is slipping.

Double tops and double bottoms

A double top or bottom marks two unsuccessful attempts to break through the same resistance or support level.

• A double top looks like the letter M. Price rallies to resistance, pulls back, rallies to roughly the same level again and fails. The low between the two peaks becomes the confirmation line, and a break below it signals a reversal lower.
• A double bottom looks like the letter W. Price drops to support, bounces, falls back to about the same level and is rejected again. The two troughs at the same height indicate sellers are weaker than they were on the first decline. A break above the intervening high signals a reversal higher.

The key word is confirmation. Until price breaks the middle swing point, an apparent double top may simply be a range, and the market can still go on to break the resistance.

Triple tops and triple bottoms

Triple tops and bottoms work the same way, except price tests the same support or resistance level three times and cannot get through. They may appear less often than head and shoulders or double tops and bottoms. Each failed test adds to the evidence that the level is firmly defended, so traders treat a confirmed break as a strong reversal signal.

Gaps

A gap is empty space between two trading periods. It occurs when price opens well above or below the prior period’s range, usually after news. For example, a stock might close at $5.00 and open at $7.00 after a strong earnings report. Gaps can signal reversals, new trends or the continuation of an existing trend. The trend-related types are:

• Breakaway gap: forms at the start of a trend, often as price leaves a consolidation or completes a pattern.
• Runaway (measuring) gap: forms in the middle of a trend as momentum accelerates.
• Exhaustion gap: forms near the end of a trend, a last burst before the move runs out of steam.

Many chartists also identify a common gap, a small gap inside a trading range that carries little meaning and is often filled. Gaps are most visible on stock charts because exchanges close overnight. In around-the-clock markets such as spot forex, they mostly appear over weekends (see forex trading sessions).

Volume: the confirmation layer

A pattern describes price. Volume describes how much participation sat behind it. Across flags, pennants, wedges and many triangles, volume usually contracts while the pattern forms, as fewer traders commit during the pause, and expands when price breaks out, showing a new wave of participation in the breakout direction.

A breakout on thin volume is easier for the market to reverse, so many traders wait for an expansion before acting. For reversal patterns such as the head and shoulders, a rise in volume on the neckline break serves the same confirming role. Spot forex has no centralized volume figure, so currency traders typically use tick volume or rely more heavily on closes beyond the pattern boundary.

Turning a pattern into a trade plan

Recognizing a shape is only the first step. Each pattern offers a logical place to enter, a place where the idea is proven wrong, and a projected target.

Entry: wait for the close

The common trigger is a close beyond the pattern boundary, not an intraday poke through it. A price that briefly pierces resistance and then closes back inside the triangle has not broken out. Some traders enter on the breakout close. Others wait for a retest, where price returns to the broken level (old resistance now acting as support, or the reverse) and holds.

Target: the measured move

Most classical patterns use a measured-move convention: take the height of the pattern and project it from the breakout point.

• Triangles: height of the widest (left) side, projected from the breakout.
• Head and shoulders: distance from the head to the neckline, projected from the neckline break.
• Double top or bottom: distance from the peaks (or troughs) to the middle swing point, projected from the break of that point.
• Flags and pennants: often the length of the flagpole, projected from the breakout of the consolidation.

Hypothetical example (for illustration only): a stock forms a symmetrical triangle whose left side runs from a low of $40 to a high of $50, a height of $10. Price closes above the upper trendline at $47. The measured-move projection is $47 + $10 = $57. This is a reference point for planning exits, not a forecast. Price may stall well short of it or run past it.

Stop loss and position size

The stop goes where the pattern would be invalidated, typically just inside the opposite side of the pattern or beyond the most recent swing point. In the triangle example, a trader might place the stop below the last swing low inside the triangle.

Continuing the hypothetical: with an entry at $47 and a stop at $44.50, the risk is $2.50 per share. A trader with a $10,000 account who limits risk to 1% per trade ($100) would size the position at $100 ÷ $2.50 = 40 shares. The calculation assumes the stop fills at $44.50. A gap through the stop can fill at a worse price, so the realized loss could exceed $100. The position size calculator runs the same arithmetic for forex lot sizes.

Comparing the projected target with the stop distance also gives the reward-to-risk ratio. In this example, a $10 target against $2.50 of risk is 4 to 1. That ratio helps decide whether a setup is worth taking at all.

How to read a chart pattern, step by step

1. Identify the prior trend. Continuation patterns need a trend to continue and reversal patterns need one to reverse. A flag with no flagpole is just a small range.
2. Choose your time frame. Patterns appear on everything from one-minute to monthly charts. Patterns on higher time frames take longer to form and, by the size rule above, imply larger moves. Many traders check the higher time frame first so they do not trade a small pattern straight into a major level.
3. Draw the boundaries with one consistent anchoring method, looking for at least two touches, preferably three, on each line.
4. Name the pattern by its geometry. Parallel lines suggest a flag or channel. Converging lines in opposite directions suggest a pennant or symmetrical triangle; converging lines in the same direction suggest a wedge. One flat line plus one sloped line suggests an ascending or descending triangle.
5. Confirm, then plan. Check volume, wait for a close beyond the boundary, and set the entry, stop, target and position size before entering.

Candlestick signals can sharpen the timing of confirmation. A strong-bodied candle closing through resistance tells a different story than a long upper wick that rejects it, as covered in the guide to candlestick charts. Some traders also check a momentum oscillator such as the Relative Strength Index. An RSI divergence near the second peak of a double top, for instance, adds evidence that momentum is fading.

Limitations to keep in mind

Chart patterns are an interpretive tool, not a mechanical law. Several points limit how much weight any single pattern can carry:

• Subjectivity. Two analysts can draw different trendlines on the same chart and see different patterns, especially when wicks and bodies give different anchor points.
• Hindsight bias. Completed patterns look obvious on historical charts. In real time, the right shoulder or the handle may never form, and an apparent breakout can reverse.
• False breakouts. Price can close beyond a boundary and then fall back inside. This is why stops matter even when every condition looks satisfied.
• Context. News events, earnings releases and broad market moves can override a pattern entirely, which is part of why gaps form in the first place.
• No pattern guarantees a direction. Patterns describe the balance between buyers and sellers so far. They frame probabilities and risk, not certainties.

FAQs

The Bottom Line

Traders who use chart patterns on stocks, forex, futures or crypto get the most from them as a planning framework for entries, stops, targets and position size. Confirmation through closes and volume reduces the risk of acting on false breakouts. Because patterns are subjective and can fail or be overridden by news, they frame probabilities and risk rather than guarantee a direction.
