The Range Break Set-Up
A rectangle with both sides working — a floor and a ceiling each tested more than once — and the session that finally closes outside one of them.

What to take away
- Two working boundaries, not one. A rectangle needs at least two touches on each side to be one.
- The ceiling is the level the set-up completes through, and the floor is the invalidation.
- The range's height is what any objective is scaled to, and rectangles measure more reliably than most shapes.
- The retest of the broken boundary is where most range breaks are actually decided.
- A range with no prior trend into it is a market with no opinion, and its break means correspondingly less.

Two lines, and nothing to argue about
The plainest structure on any chart. Why a rectangle measures better than most shapes, and why its failure travels further than anyone expects.
This lesson is part of a Stock Alerts + Tools plan.
The shape
Price moves between two roughly horizontal boundaries for weeks, touching each of them more than once, with no drift in either direction. Then one session closes outside the rectangle and the range is over.
It is the plainest structure on any chart and the easiest to identify honestly, which is most of its value. There is nothing to interpret about a rectangle: the two lines are either there or they are not, and unlike a triangle or a cup nobody has to decide how much curvature or convergence counts.
- At least two clear touches of the ceiling and two of the floor.
- Boundaries that are horizontal rather than sloping, so it is a rectangle and not a channel.
- A range that has lasted long enough to be a range — weeks, not three sessions.
- A prior trend leading into it, which is what gives the eventual break a direction to inherit.

Why it forms
A rectangle is two decisions being repeated. Somebody has an amount to sell at the top and somebody has an amount to buy at the bottom, and while both inventories last, price shuttles between them. The rectangle is the visible record of two participants of size disagreeing at fixed prices.
It ends when one of them finishes. That is why the break tends to be decisive rather than gradual: the constraint that was holding price inside the range is not weakened, it is removed, and the next resting orders are wherever the market last traded outside the boundaries — which can be a long way away.
Because both boundaries are being worked, a rectangle carries information a one-sided base does not: it says how much disagreement there is and at what prices. That is also why its measured objective is among the more defensible ones in use — the height of the range is a real quantity that had to be resolved, rather than an outline someone drew.
| What to look at | Set-up intact | Set-up failing |
|---|---|---|
| The boundaries | Both horizontal, both touched repeatedly | One drifting, so it is a channel or a wedge |
| Behaviour inside | Reaching both sides, with no drift | Coiling in the middle, never reaching either |
| Volume on the break | Clearly heavier than the range | Indistinguishable from a normal day |
The price points that define it
A set-up is a shape plus a handful of prices. The shape is what makes it recognisable; the prices are what make it something that can be measured, reviewed afterwards and argued about honestly. These are the levels this one is read from.
| Level | Where it sits | What it tells you |
|---|---|---|
| The ceiling | The price the rallies have all stopped at | The reference the set-up completes through, and the level the convention expects to hold as support afterwards. |
| The floor | The price the declines have all stopped at | Where the reading stops holding. A break of the ceiling that ends up below the floor is the failure this shape is most prone to. |
| The range height | Ceiling minus floor | What the measured objective is scaled to, and a direct measure of the disagreement the rectangle contains. |
| The last touch before the break | The most recent visit to either boundary | The closest reference to the break itself, and the level a genuine resolution is not expected to revisit. |
Where the set-up completes
- 1The triggerThe set-up completes on a close outside the range, with volume heavier than the range has been trading on. Because both boundaries are defined, a rectangle break is one of the few in this catalogue where the level is genuinely unambiguous — which removes the usual argument about where the line should have been drawn and leaves only the question of whether the break is real.
- 2Where the reading stops holdingThe reading stops holding on a close back inside the range, and definitively on a close beyond the opposite boundary. The first says the break failed; the second says the range resolved the other way, which is a different and larger problem for anyone who had read the shape.
- 3The measured objectiveThe conventional measured objective adds the height of the range to the breakout price. This is one of the better-supported conventions, for the reason above: the height is a measured quantity rather than an inferred one. It is still reached less often than the break follows through, and a wide range produces a target correspondingly far away.
- 4Through the moveThe convention watches the retest of the broken boundary, which is where most rectangles are settled. The old ceiling holding as support is the confirmation the shape offers; price cutting back through it is not a pause but the beginning of the failure case, and rectangles fail all the way back to the opposite side more often than intuition suggests.
Each of these describes where a convention puts a level, not what anybody should do at it. Whether a level is worth acting on at all is a question about position size, cost and the rest of a plan, and the answer differs for every account.
How often it follows through
Long rectangles with several touches a side, following a clear trend, and breaking in the trend's direction on real volume sit at the top of this band. A break against the prior trend, or out of a range that has only lasted a fortnight, sits at the bottom of it.
Read that as a floor rather than an expectation. A set-up that follows through two times in three still leaves one in three that does not, and the one that does not can move further and faster than the two that did. That arithmetic is what position sizing exists to answer, and no pattern improves it.
What this number is not
It is not our record, it is not a forecast for any particular chart, and it is not the rate at which the measured objective is reached — that is always lower. It is a conservative reading of how often a completed range break kept going before it went back through the level that invalidates it. Base rates move with the market, the timeframe and the exact definition used, and every one of those varies.
What failure looks like
The failure is the whipsaw, and rectangles produce the cleanest examples of it anywhere. Price closes above the ceiling, brings in everyone watching the level, fails to hold, and then travels the entire height of the range to the floor — and often through it. Because the boundaries are so visible, the positioning around them is unusually one-sided, which is exactly what makes the reversal large.
- The break closes outside the range on ordinary volume.
- Price closes back inside the range within a couple of sessions.
- The range never really reached both boundaries — it coiled in the middle instead.

Seeing it on a live chart
Rectangles are the one structure worth setting an alert on, because both levels are unambiguous and neither moves. Mark the ceiling and the floor when the range is identified, and the chart tells you which one went without anybody watching it.
