Chart Patterns Explained: the most important formations

Basics · ~7 min read

Chart patterns are recurring formations in price action that many traders rely on. They show how supply and demand behave in a given phase – and hint whether a trend is more likely to reverse or continue. This overview explains the most important patterns in plain language and shows how you can stop hunting for them by hand.

Chart patterns generally fall into three groups: reversal patterns, continuation & range patterns and harmonic patterns. These are exactly what our chart pattern scanner detects automatically across Forex, Crypto, Stocks and Commodities.

1. Reversal patterns

Reversal patterns suggest an existing trend is losing strength and may turn around.

Double Top & Double Bottom

In a Double Top, price fails twice at roughly the same level – a sign buyers can no longer push new highs. The Double Bottom is the mirror image: two lows at a similar level where sellers stall. The pattern is confirmed when price breaks the neckline.

Triple Top & Triple Bottom

Like Double Top/Bottom but with three touches. Three highs (or lows) at the same level are an even stronger sign that a barrier is holding.

Head & Shoulders (and inverse)

The Head & Shoulders pattern consists of three highs: two shoulders and a higher head in the middle. A break below the neckline through the two troughs is a bearish reversal signal. The inverse Head & Shoulders is the bullish version after a downtrend.

Rising & Falling Wedge

In a rising wedge, two upward-sloping lines converge – despite rising prices the move loses momentum, which often resolves bearishly. The falling wedge is the bullish counterpart.

2. Continuation & range patterns

These usually form inside a trend and suggest the move continues after a pause.

Triangles

In a symmetrical triangle, a falling upper line and a rising lower line converge – the breakout can go either way. The ascending triangle (flat top, rising lows) leans bullish, the descending triangle (flat bottom, falling highs) leans bearish.

Rectangle / Range

Price oscillates between horizontal resistance and horizontal support. Only the breakout from the range defines the direction.

Flag & Pennant

After a strong, fast move (the "pole") comes a short consolidation – a small counter-move (flag) or a small triangle (pennant). The trend usually resumes afterwards.

Cup & Handle

A rounded, U-shaped base (the "cup") followed by a small consolidation on the right rim (the "handle"). A break above the rim is the classic bullish signal.

3. Harmonic patterns

Harmonic patterns such as Gartley, Bat, Butterfly, Crab and ABCD are based on fixed Fibonacci ratios between the individual swings (points X-A-B-C-D). They are more demanding because the proportions must line up precisely – but in return they mark potential turning points very accurately.

Find chart patterns automatically

Hunting for all these formations by hand across hundreds of instruments and several timeframes is tedious. That's where a scanner helps: our chart pattern scanner searches Forex, Crypto, Stocks and Commodities automatically and marks the detected patterns directly on the chart – including neckline, trendlines and a projected target. At a glance you see which formations are forming or have already broken out.

Individual patterns in detail

• Head and Shoulders – structure, neckline & price target
• Double Top & Bottom – the M and W pattern
• Cup and Handle – the bullish continuation setup
