20 Chart Patterns Every Trader Should Know

Chart patterns are the visual fingerprints of supply and demand. When enough traders react to the same price structure, that structure starts to predict what comes next, which is exactly why pattern recognition sits at the heart of technical analysis. Below are the 20 trading patterns PatternX detects across crypto and traditional markets, grouped by directional bias so you know what each one is telling you.

Bullish reversal and continuation patterns

These formations suggest buyers are gaining control, either flipping a downtrend or refueling an existing uptrend.

Cup & Handle. A rounded, U-shaped base followed by a small downward-drifting consolidation (the handle) that looks like a teacup in profile. A breakout above the handle typically signals continuation of the prior uptrend.

Inverse Head & Shoulders. Three troughs where the middle low (the head) is deeper than the two surrounding lows (the shoulders), joined by a neckline. A close above the neckline is a classic reversal signal from bearish to bullish.

Double Bottom. Price tests a support level twice, forming a distinct W shape without breaking lower. It marks seller exhaustion and often precedes a rally once the middle peak is breached.

Triple Bottom. The same idea as a double bottom but with three failed pushes into support, making the base more reliable. The extra test signals stubborn demand and a higher-conviction reversal on breakout.

Ascending Triangle. A flat horizontal resistance line capping a series of higher lows that press upward. The rising floor usually wins, resolving in an upside breakout.

Falling Wedge. Two downward-sloping, converging trendlines where price action tightens as it drifts lower. Despite the downward tilt, it is a bullish pattern that tends to break to the upside.

Bullish Flag. A sharp rally (the flagpole) followed by a small, orderly downward-channeling pullback. It is a brief pause before the trend resumes higher.

Bullish Pennant. Like a bullish flag, but the consolidation forms a small symmetrical triangle instead of a channel. It signals a momentary rest before continuation of the uptrend.

Bullish Rectangle. Price trades sideways between clear horizontal support and resistance during an uptrend. The range represents accumulation, and a break above the top usually continues the move up.

Rounding Bottom. A slow, saucer-shaped curve that reflects a gradual shift from selling to buying pressure. It signals a long-term reversal and the start of a new uptrend once price clears the rim.

Bearish reversal and continuation patterns

These mirror their bullish counterparts and suggest sellers are taking over.

Head & Shoulders. Three peaks with a taller middle peak (the head) flanked by two lower peaks (the shoulders), sitting on a neckline. A break below the neckline is one of the most recognized reversal signals from bullish to bearish.

Double Top. Price rejects a resistance level twice, forming an M shape without breaking higher. It marks buyer exhaustion and often precedes a decline once the middle trough gives way.

Triple Top. Three failed attempts to break resistance rather than two, reinforcing the ceiling. The added rejection strengthens the bearish reversal case on breakdown.

Descending Triangle. A flat horizontal support line beneath a series of lower highs pressing downward. The falling ceiling usually prevails, resolving in a downside breakdown.

Rising Wedge. Two upward-sloping, converging trendlines that squeeze price higher on fading momentum. Despite the upward tilt, it is a bearish pattern that tends to break to the downside.

Bearish Flag. A sharp sell-off (the flagpole) followed by a small upward-channeling bounce. It is a pause before the downtrend resumes lower.

Bearish Pennant. Like a bearish flag, but the consolidation forms a small symmetrical triangle. It signals a brief rest before continuation of the downtrend.

Bearish Rectangle. Price ranges sideways between horizontal support and resistance during a downtrend. The consolidation represents distribution, and a break below the floor usually continues the move down.

Rounding Top. A slow, inverted saucer that reflects a gradual shift from buying to selling pressure. It signals a long-term reversal and the start of a new downtrend once price loses the rim.

Bilateral patterns

Some structures do not commit to a direction until price breaks out.

Symmetrical Triangle. Two converging trendlines formed by lower highs and higher lows that coil price into an apex. It is a bilateral pattern that trades whichever way it breaks, so the breakout direction, not the shape, defines the bias.

How PatternX reads all 20 in real time

Naming a pattern is easy; confirming one is not. A shape that merely looks like a Double Bottom means little without corroboration, which is why every PatternX detection uses strict geometry confirmed by volume, trend context and order-book strength. That layered check is what separates a tradable signal from a chart that happens to resemble a textbook diagram, and it is the core of how [PatternX evaluates confidence](/blog/how-patternx-evaluates-confidence) on each formation.

PatternX scans for all 20 patterns in two complementary modes. The Classic mode is fully deterministic, applying the same fixed geometric rules every time so results are transparent and repeatable, which is exactly [why deterministic trading still matters](/blog/why-deterministic-trading-still-matters) when you need to trust and audit a signal. The AI mode adds adaptive detection that handles noisier, real-world price action, and you can read more about [what makes the PatternX AI different](/blog/what-makes-patternx-ai-different) from generic model-driven tools.

The real edge comes when signals stack. A Falling Wedge that lines up with a Double Bottom at the same support zone is far stronger than either pattern alone, a principle we cover in [pattern confluence explained](/blog/pattern-confluence-explained). Learning to spot when multiple patterns agree is one of the fastest ways to raise the quality of your entries.
