Are You Seeing a Pattern—or Just Seeing What You Want?

Humans are excellent at finding shapes—even when the evidence is weak. On a chart, almost any cluster of candles can become a triangle, flag or head and shoulders if you want it badly enough.

A pattern becomes useful when its boundaries, prior movement and confirmation can be defined consistently. The name is secondary. The structure is the real information.

Patterns are organised market structure

Chart patterns describe how price behaves during pauses, compression and attempted reversals.

Every useful pattern should answer:

• What movement came before it?
• Which swing points define its boundaries?
• Is price compressing, expanding or repeatedly failing?
• What event confirms that price has left the structure?
• What event proves the interpretation wrong?

Without those answers, a pattern name can become decoration.

Continuation and reversal are hypotheses

Patterns are often divided into:

• Continuation patterns: structures expected to resolve in the direction of the preceding move.
• Reversal patterns: structures suggesting that the previous trend may be losing control.

These labels describe typical interpretations, not guaranteed outcomes. A continuation pattern can break against the prior trend. A reversal pattern can fail and restart the old direction.

Wait for price behaviour to confirm which scenario is developing.

Triangles: compression toward a decision

A triangle forms when price swings narrow between converging boundaries.

Symmetrical triangle

Lower highs meet higher lows. Both sides compress, and direction remains unresolved until price breaks and holds beyond a boundary.

Ascending triangle

Repeated highs form a relatively flat ceiling while swing lows rise. Buyers appear increasingly willing to transact at higher prices, but resistance remains intact until it is actually broken.

Descending triangle

Repeated lows form a relatively flat floor while swing highs fall. Selling pressure may be building, but support remains valid until price proves otherwise.

The textbook directional tendency should never replace confirmation or broader context.

Flags and pennants: pause after expansion

A flag normally begins with a fast directional move called the flagpole, followed by a smaller, controlled countertrend channel or rectangle.

A pennant is similar, but its pause compresses into a small triangle.

Useful characteristics include:

• A clear directional move before the pause.
• A correction that is smaller and less urgent than the flagpole.
• Contained, overlapping price action during the pause.
• A break from the pause with renewed directional participation.

A sideways rectangle without a meaningful move before it is not automatically a flag. The prior expansion provides the context.

Double tops and double bottoms

A double top develops when price tests a similar high twice and cannot sustain progress. A double bottom develops when price tests a similar low twice and cannot sustain further decline.

The pattern is not confirmed merely because two peaks or troughs look similar. Traders commonly watch the swing between them—the neckline.

For a double top, a break below the intervening swing low provides evidence that support has failed. For a double bottom, a break above the intervening swing high provides evidence that resistance has failed.

Even after confirmation, price can retest the neckline or return into the pattern.

Head and shoulders

A head-and-shoulders top usually contains:

1. A left shoulder formed during the existing uptrend.
2. A higher peak called the head.
3. A right shoulder that fails to match the head.
4. A neckline connecting the intervening lows.

The structure suggests weakening upward progress. Confirmation normally requires a meaningful break of the neckline—not simply the appearance of three peaks.

The inverse version applies the same logic after a decline.

Measured moves are estimates, not promises

Classical pattern analysis sometimes projects the height of a structure from its breakout point. For example, the vertical height of a rectangle may be projected beyond the break.

This is a reference—not a guaranteed target. Before using it, consider:

• Intervening support or resistance.
• Higher-timeframe structure.
• Volatility and market conditions.
• Whether the breakout remains accepted.

Never ignore a major opposing zone because a textbook projection extends farther.

The pattern-quality test

A clearer pattern usually has:

• Comparable swing points.
• Boundaries visible without excessive adjustment.
• Sufficient time to develop.
• A logical relationship with prior structure.
• A definable confirmation event.
• A definable failure event.

If five traders would need five completely different lines to see the pattern, its decision value may be low.

Common pattern traps

• Naming a pattern before enough swing points exist.
• Ignoring the movement that came before it.
• Entering before the boundary breaks because the shape “looks complete.”
• Moving the neckline after price violates it.
• Treating a measured move as guaranteed.
• Finding a reversal pattern on every market top or bottom in hindsight.

Lesson takeaway

Read patterns as organised price behaviour. Start with prior movement, define comparable boundaries and wait for confirmation. A recognisable shape without context is not a complete trading idea.

Next, you will examine Fibonacci retracements—why traders watch them, how anchor choice changes them and why they should never stand alone.
