Wedge pattern

A wedge pattern is a chart formation with two converging trendlines, similar in shape to a symmetrical-triangle or pennant, but with a clear directional bias. Unlike symmetrical triangles (which are neutral), wedges are either rising (bullish) or falling (bearish) in appearance. A rising wedge shows both lines sloping upward, though converging. A falling wedge shows both lines sloping downward, though converging. Wedges can act as either reversal or continuation patterns depending on their context in the larger trend. A rising wedge within an uptrend may precede a downward reversal; the same shape appearing within a downtrend may signal continuation lower.

Rising wedge

A rising wedge consists of two upward-sloping lines that converge toward each other. Both the upper line (resistance) and lower line (support) are rising, but the resistance line is falling more steeply toward the lower line than the lower line is rising toward resistance. The wedge appears to be pointing upward but is narrowing.

A rising wedge in the context of an uptrend is often a bearish warning—the price is making higher highs and higher lows (uptrend), but the range is narrowing. The narrowing suggests momentum is exhausting. A break below the lower line often signals a reversal downward.

A rising wedge in a downtrend can signal continuation lower—the consolidation precedes further decline.

Falling wedge

A falling wedge consists of two downward-sloping lines that converge. Both the upper and lower lines are falling, but at different rates, narrowing the range. The wedge appears to be pointing downward but is narrowing.

A falling wedge in the context of a downtrend is often a bullish warning—the price is making lower lows (downtrend), but the range is narrowing. This convergence can signal exhaustion of selling, and a break above the upper line often signals a bullish reversal.

A falling wedge in an uptrend can signal continuation higher—the consolidation precedes further rise.

Wedge versus triangle

The key difference from triangles is slope:

• Symmetrical triangle: One line rises, one falls; they converge (no directional bias).
• Wedge: Both lines slope in the same direction (either both up or both down); they converge (has directional bias).

This difference in slope gives wedges their characteristic directional appearance.

Context and reversal/continuation

Wedges are unusual in that they can signal either reversals or continuations depending on where they form:

• Rising wedge in uptrend → bearish reversal signal (momentum exhausting).
• Rising wedge in downtrend → bullish continuation signal (further down expected).
• Falling wedge in downtrend → bullish reversal signal (selling exhausted).
• Falling wedge in uptrend → bearish continuation signal (further up expected).

This dual interpretation makes wedges trickier than simpler patterns.

Volume during wedge formation

Volume typically declines as the wedge develops, reflecting consolidation and indecision. On the breakout, volume should surge in the direction of the break. High volume confirms the breakout; low volume suggests a fakeout is possible.

Measuring the target

The measuring objective is similar to other converging patterns: the height of the widest part of the wedge, projected in the breakout direction.

Trading wedges

Identify context: Determine whether the wedge is in an uptrend, downtrend, or neutral market.

Anticipate breakout: Use the directional slope to anticipate which direction is more likely (though not guaranteed).

Wait for confirmation: Enter on a high-volume break of the appropriate boundary.

Stop-loss: Place on the opposite side of the breakout boundary.

Profit target: Use the measuring objective.

Real-world example

A stock rises from $80 to $120 (uptrend). It then consolidates in a rising wedge from $118, $115, $117, $114, $116, $113 (higher highs, higher lows, but narrowing). If it breaks below $113 on volume, a bearish reversal is signalled. The measuring objective might be $113 - (height of wedge at widest).

Academic perspective

Academic research on wedges is sparse. The pattern’s dual interpretation (reversal or continuation depending on context) makes it harder to study systematically.
