Rectangle Pattern

What is a rectangle pattern?

A rectangle pattern is a chart pattern in which price moves sideways between a roughly horizontal resistance level above and a roughly horizontal support level below, with at least two touches of each boundary. A confirmed break beyond either boundary resolves the pattern, and the range height, projected from a chosen anchor, sets the measured-move target. Comparing the breakout direction with the preceding trend marks it as a continuation or a reversal.

The boundaries are Support and Resistance levels: at least two highs establish the upper boundary and two lows establish the lower one. A Triangle narrows toward an apex. A rectangle keeps approximately parallel horizontal boundaries.

How to identify a rectangle: swing and tolerance rules

The example has highs of $53.90, $54.10 and $53.95, alternating with lows of $48.05 and $47.95. The trader draws the boundaries at $54 and $48.

The highs average $53.98, and the largest deviation, $0.12, sits inside the $0.40 band that 0.75% allows. The lows average $48, each $0.05 away, inside a $0.36 band.

Five alternating swings define this box. The third high at $53.95 counts as a peak only once price turns down from it, which is why a rectangle confirms after the fact.

Rectangle range plan vs breakout plan

A range plan trades around support and resistance while price remains inside the box. A breakout plan activates on a defined event beyond a boundary, such as a close above $54. Define the trigger, order type, entry and invalidation before the move.

Here the breakout rule requires a close above $54. The first excursion reaches $54.40, followed by a $53.60 close, so that rule stays inactive. The later close at $54.80 activates it.

Compare volume with a fixed baseline. In this example, breakout volume is 2.4 times the preceding 20-session average. Use Relative Volume and Average True Range to add participation and price-distance context.

How to calculate a rectangle pattern target

Range height = $54 − $48 = $6. Projecting from resistance gives $60; projecting down from support gives $42.

For the upward example, assume a $54.80 entry and $53.10 stop reference. Entry-to-stop distance is $1.70. Entry-to-target distance is $60 − $54.80 = $5.20, producing a 3.06 ratio.

An alternative projection from the breakout close gives $60.80. Pick one anchor before entry and set the exit there; this plan uses the $60 boundary target.

The example returns to $54.20, then advances to $59.70, finishing $0.30 below the boundary objective.

Iron condor example for a rectangle range

A same-expiration Iron Condor can place its inner strikes at $48 and $54. Buy the $46 put and $56 call, sell the $48 put and $54 call, and assume a $0.50 net credit per share.

With a 100-share multiplier, maximum gross expiration profit is $50 and maximum gross expiration loss is ($2 − $0.50) × 100 = $150. Expiration breakevens are $47.50 and $54.50. The maximum-profit interval lies between the inner strikes.

Set expiration and compare each boundary’s distance from spot with the Expected Move for that same horizon. Add the actual premium and payoff to compare the range expression with a directional breakout structure.

Inspect the ticker in Options Flow and compare both structures in the Options Profit Calculator using the $54 trigger, the $60 objective and your expiration. Keep the range plan and breakout plan attached to their own entries, invalidations and expirations.

Limitations of the rectangle pattern

• Require a close beyond the boundary. The first excursion to $54.40 closes back inside at $53.60, and the close rule keeps that probe from counting.
• Set the box rules before you trade it. The number of touches, the swing rule and the 0.75% tolerance decide whether this range qualifies, so apply the same rules to every chart.
• Pick the target anchor before entry: $60 from the boundary or $60.80 from the breakout close. In the example price stops at $59.70, $0.30 short of the boundary target, so scale out as price nears it.
• Count a swing only after price turns from it. The third high counts as a peak only after the decline that follows it, and the box confirms with that turn.
• Close or adjust a range trade when price breaks through a short strike. The example iron condor risks $150 to make $50 at expiration, before costs, and a breakout beyond either short strike moves it toward that loss.

Bottom line

A rectangle is a sideways range between horizontal support and resistance that resolves on a confirmed break beyond one boundary. Choose a range plan or a breakout plan before the move, define the activation rule and target anchor, and size the trade from the stop distance rather than the range height.
