Rectangle chart pattern: trading ranges, breakouts and targets
How to identify a rectangle (trading range), why it has no built-in direction, how to measure the breakout target, and real rectangles that broke up, down and failed.
On this page
A rectangle is a trading range drawn as a box. Price bounces between a roughly flat ceiling (resistance) and a roughly flat floor (support), touching each several times, until it finally closes outside the box. While it lasts, buyers and sellers are in balance: buyers step in at the same low price, sellers at the same high price, and neither side is willing to pay more.
Unlike a triangle or a wedge, a rectangle does not narrow, and unlike a head and shoulders it does not tilt the odds in either direction by its shape. Classical texts call it a continuation pattern, because ranges most often form as pauses in a trend, but they also note that rectangles appear at tops and bottoms. In practice the rectangle tells you where the decision levels are, and the breakout tells you which way it was decided.
This guide covers how to draw a rectangle, the measured-move target, how to trade inside and out of the range, and three real examples on US stocks: an upside breakout, a downside breakout, and a breakdown that reversed within two weeks.
Anatomy of a rectangle
- A flat ceiling. Two or more highs at about the same price. Every rally into it meets enough selling to turn back.
- A flat floor. Two or more lows at about the same price. Every dip to it meets enough buying to turn up.
- A constant width. The swings stay about the same size. If they shrink, the pattern is a triangle. If both lines tilt the same way, it is a channel or a wedge.
- Duration. On daily charts, a few weeks to several months. Five or more alternating touches make the boundaries convincing.
- The breakout. A close above the ceiling or below the floor.
Rectangles overlap with other patterns. Three touches of the ceiling after an advance can be read as a triple top. Two touches of each line can be a double top or bottom. The difference lies in expectations: a triple top is read as a reversal, a rectangle as a neutral range. The levels and the breakout rule are the same.
Volume inside the range
In the classical description, volume tends to fade during a long rectangle as participants wait, and expands on the breakout. A breakout on heavy volume is considered more trustworthy than one on light volume. The Darvas box, popularized by dancer and trader Nicolas Darvas in the 1960s, is a related idea: he stacked rectangles of consolidation in rising stocks and bought breakouts above each box's top.
Target, stop and two ways to trade it
Rectangles support two different approaches, both outlined here for education only:
- Trading the breakout. Wait for a close outside the box, enter in that direction, and use the opposite side of the box (or the broken boundary) as the stop. The measured target is the height of the range.
- Trading the range. Buy near the floor and sell near the ceiling while the range holds, with a stop just outside the box. This works only as long as the range does. The breakout, when it comes, stops out one side.
The breakout approach accepts more false starts in exchange for catching the move once a range ends. The range approach collects small, frequent gains and occasionally takes a large loss.
Three real rectangles
The examples were found by the rules described below. The orange lines run through the first and last swing high and the first and last swing low. The shaded column marks the session the outcome was decided.
Procter & Gamble, 2026: an upside breakout. From August to September 2026, PG rallied to about $148.50 three times ($148.50 on August 6, $148.36 on September 1 and $149.48 on September 28) and dipped to about $142 twice ($142.14 on August 21 and $141.86 on September 10). On October 8 it closed at $150.59, above the ceiling. The range's height of about $6.36 projected a target near $156.95, and the stock traded there on October 15, five sessions later.
McDonald's, 2025: a downside breakout. MCD spent April and May 2025 in a box: highs of $318.20, $321.78 and $321.72, lows of $305.12 and $305.01. After a slow drift down from the ceiling, the stock closed at $304.78 on June 9, just under the floor. The height projected a target of about $291.70, 4.3% lower, and the stock reached it on June 18, seven sessions later. The breakdown close was only a few cents below the floor, the kind of marginal signal many traders would have waited to see confirmed.
Wells Fargo, 2025: a breakdown that reversed. WFC traded between roughly $83 and $88.60 from late October to mid-November 2025, with highs of $88.50 and $88.64 and lows of $83.14, $84.04 and $82.54. On November 20 it closed at $82.40, below the floor, which projected a target near $77. The next day it traded down to $81.05, and then it turned. On December 3 it closed at $89.35, above the ceiling. A short seller who used the ceiling as a stop lost the full height of the range. A trader who treated the failed breakdown as information, and bought the move back above the ceiling, was on the right side of the next leg.
What our data says about rectangles
We searched the same 60 large US stocks and ETFs used in our other pattern tests with a 3% ZigZag, looking for five alternating swings whose upper and lower lines both changed by less than 1.5% over the pattern and stayed roughly the same distance apart. Over two years of daily bars the rules found only 10 completed rectangles with a resolved outcome. That is too few for a meaningful hit rate, so we do not publish one. Strict flatness is rare. Most ranges in real data tilt a little, and loosening the rule quickly turns rectangles into channels, triangles and wedges.
Two points held regardless of the threshold:
- Breakouts went both ways, with no consistent bias by direction of the prior trend in our small sample.
- Failures were often fast. Wells Fargo's reversal took eight sessions. The far side of the box is close by, which makes rectangle failures cheap to identify but frequent.
For larger samples, Bulkowski's Encyclopedia of Chart Patterns splits rectangles into "tops" and "bottoms" by the trend that precedes them and catalogs their breakouts.
Common mistakes
- Drawing boundaries through bodies. If you have to cut through several candles to make the lines flat, the range is not as clean as it looks. Allow a small zone rather than a single price.
- Acting on a marginal break. A close a few cents beyond the line, as with MCD, is a weak signal. Some traders require a close a set percentage beyond the line, or a second close.
- Assuming the prior trend continues. Rectangles are called continuation patterns, but our examples broke both ways. Let the breakout decide.
- Ignoring false breakouts. A close back inside the box after a breakout is a warning, and a move through the other side is a signal in its own right.
Rectangles compared with similar patterns
| Pattern | Boundaries | Width | Typical reading |
|---|---|---|---|
| Rectangle | Flat ceiling and flat floor | Constant | Neutral; trade the breakout |
| Ascending triangle | Flat ceiling, rising floor | Narrowing | Bullish bias |
| Descending triangle | Falling ceiling, flat floor | Narrowing | Bearish bias |
| Rising channel | Parallel lines sloping up | Constant | Uptrend in progress |
| Flag | Small parallel channel | Constant | Short pause after a steep pole |
| Triple top or bottom | Three tests of one boundary | Roughly flat | Reversal after a trend |
How Finabase helps you work with ranges
Finabase does not detect rectangles automatically. Its charts give you what you need to draw and test them yourself:
- The rectangle and horizontal line tools. Every symbol's chart has a rectangle tool for boxing a range and a horizontal line tool for the ceiling, the floor and the target. Signed-in users' drawings are saved per symbol. Try boxing the 2026 range on the one-year PG chart.
- ZigZag study. A 3% ZigZag, as on this two-year MCD chart, marks the swings that define the box. See the ZigZag indicator: filtering swings, and why the last leg repaints guide.
- Bollinger Bands. Ranges often coincide with narrowing Bollinger Bands: formula, the squeeze and walking the bands, a "squeeze" that some traders watch for an approaching breakout. Add them to a chart, as on this WFC example.
- The Scanner. The Scanner lists stocks gapping or making new 52-week highs and lows. A stock that leaves a long range by gapping will often appear there.
Frequently asked questions
Is a rectangle bullish or bearish?
Neither by itself. It is a balance between buyers and sellers. It turns bullish when price closes above the ceiling and bearish when it closes below the floor.
How many touches does a rectangle need?
At least two on each boundary. More touches make the levels more convincing, and they also make the eventual breakout more significant, because more traders are watching the same prices.
What is the difference between a rectangle and a channel?
A rectangle's boundaries are flat. A channel's boundaries are parallel but sloped, up or down, so the range moves with the trend.
How long does it take to reach the target after a breakout?
It varies. In our examples PG took five sessions and MCD seven. Many breakouts never reach the full height, and some, like Wells Fargo's, reverse before getting close.
Summary
A rectangle is the simplest chart pattern: a flat ceiling, a flat floor, and a market that cannot decide between them. It carries no reliable bias of its own, which makes it honest. The boundaries tell you where the decision will be made and the height gives a rough objective, but only the breakout tells you the direction. Our examples covered all three outcomes: a clean upside break, a downside break that reached its target, and a breakdown that reversed and broke out the other way. Draw the box carefully, wait for a decisive close outside it, and plan for the failure as carefully as for the follow-through.
