What is Rectangle?

A rectangle is a consolidation pattern where price bounces between horizontal support and resistance, forming a clear box on the chart. It marks a pause where buyers and sellers are balanced; it usually resolves as a continuation — breaking out in the direction of the prior trend — but can reverse.

A rectangle forms when price oscillates between two roughly horizontal levels — a flat resistance ceiling and a flat support floor — touching each at least twice, so a box shape is visible. Unlike a triangle, neither boundary is sloping: it's a stand-off. Each touch of resistance is sold and each touch of support is bought, so the pattern represents a market catching its breath rather than trending.

Rectangles are usually continuation patterns — after a pause, price tends to break out in the direction of the trend that preceded the box — though they can also mark reversals. The trigger is a decisive close outside the box, ideally on rising volume, and the measured target projects the box's height in the breakout's direction. Inside the box, some traders 'range trade' the bounces; most wait for the break.

Price bounces between flat support and resistance in a clean box, then breaks out — usually continuing in the direction of the trend that preceded it.

For example

After a rally, a stock trades between $50 support and $56 resistance for several weeks, bouncing between them — a rectangle. It then closes above $56 on strong volume, projecting a continuation toward about $62 (the $6 box height added to $56).

Why it matters to you

A rectangle is one of the easiest patterns to trade around because its boundaries are dead flat and unambiguous — you know exactly where the breakout and your invalidation are. It also frames a key decision: whether a pause in the trend will resolve as a continuation (the usual case) or a reversal.

⚠ Wait for the box to break

The trap is anticipating the breakout direction before it happens and getting caught by a fakeout. Rectangles are notorious for false breaks — a poke outside the box that snaps back. The reliable signal is a decisive close beyond a boundary, ideally with a volume surge or a successful retest, not the first touch outside.

Frequently asked questions

Is a rectangle a continuation or reversal pattern?

Usually a continuation — price tends to break out of the box in the same direction as the trend that preceded it, resuming after the pause. But rectangles can also mark reversals, so the pattern itself is neutral until it breaks; the breakout direction is what matters.

What's the difference between a rectangle and a range?

They're essentially the same shape — price oscillating between horizontal support and resistance. 'Range' usually describes the sideways condition generally, while 'rectangle' refers to it as a defined chart pattern with a measured target and a breakout you're waiting to trade.

How do you trade a rectangle?

Two ways: range-trade the bounces (buy near support, sell near resistance while the box holds), or wait for a decisive close outside the box and trade the breakout with a stop back inside. The measured target adds the box's height to the breakout level.

What is the price target for a rectangle breakout?

Measure the height of the rectangle — the distance between support and resistance — and project it from the breakout point in the direction of the break. As with all measured moves, it's an estimate, best combined with other levels for managing the trade.

It signals sellers have overwhelmed the buyers defending support, and often triggers a fast move lower as stops and new sellers pile in.
