# Breaker block > An order block consumed by a move that first swept a prior extreme and then broke structure — after which the taxonomy expects the failed zone to act in its flipped role. - Canonical: https://hadalinstruments.com/glossary/breaker-block/ - Term set: https://hadalinstruments.com/glossary/ --- The breaker block is the taxonomy's most ceremonious failure — an order block that died the *right* way, and is expected to haunt the chart for it. The construction is a three-beat sequence, each beat parameterised. First, an [order block](/glossary/order-block/) exists under a stated identification rule, the last opposing candle before a qualifying move. Second, a counter-move arrives that **sweeps a prior extreme**: trades through a qualifying high or low, collecting the pool resting beyond it, per the [liquidity sweep](/glossary/liquidity-sweep/) test. Third, that same move **closes through the block and breaks structure** — the [break of structure](/glossary/break-of-structure/) or [change of character](/glossary/change-of-character/) that certifies the old direction's failure. The block's zone — full range or body, an election — is then re-registered in the flipped role: a failed bullish block becomes expected resistance, a failed bearish one expected support. The sweep is what separates the breaker from its sibling. A block consumed without the prior raid — from a plain failure swing — is a [mitigation block](/glossary/mitigation-block/), and the taxonomy consistently grades the swept origin as the stronger flip. The reasoning is the vocabulary's usual intent story: the sweep collected fuel, the reversal stranded the block's builders harder, the zone's second career inherits the energy. As a ranking of two *expectations* it is at least internally coherent; as a ranking of outcomes it is unmeasured, and the sweep-versus-no-sweep comparison is exactly the kind of well-posed test the construction's precision makes possible. The third member of the failure family is the [inverse fair value gap](/glossary/inverse-fair-value-gap/): same flip narrative, different parent, a failed imbalance rather than a failed position candle. Keeping the three separate is most of what fluency in this corner of the vocabulary amounts to: which object died, how it died, and which zone its ghost is supposed to hold. What none of the three come with is the frequency. That a revisit reacts at a flipped zone more than at a matched neutral level is the claim every one of these names is quietly making, and it is a measurable claim — revisit behaviour, matched controls, era by era. The [two lenses](/glossary/the-two-lenses/) close this page the way they close its siblings: the construction is checkable and stated; the haunting is a hypothesis, and hypotheses earn their keep in data or not at all. ## Commonly confused with Neighbouring concepts that get used interchangeably, and the distinction that actually separates them. - **[Order block](https://hadalinstruments.com/glossary/order-block/)** — The parent object. An order block is the last opposing candle before a qualifying move, expected to hold on revisit. The breaker is that block after a specific death — swept first, then broken through — with the expectation reversed. Same candle on the chart, different name, opposite bet. - **[Mitigation block](https://hadalinstruments.com/glossary/mitigation-block/)** — The no-sweep sibling. Both are failed order blocks expected to flip roles; the breaker's consuming move first raided a prior extreme, the mitigation block's came from a failure swing that took nothing. The taxonomy grades the swept origin stronger — a ranking of expectations, not of measurements. - **[Inverse fair value gap](https://hadalinstruments.com/glossary/inverse-fair-value-gap/)** — The other role-flip object, from a different parent: a failed three-candle imbalance rather than a failed position candle. The flip narratives rhyme, the drawn zones differ, and charts routinely show one without the other. - **A support-resistance flip** — The classical flip is a horizontal level with touch history changing sides. The breaker is a zone from one candle's geometry, flipped by a dated two-step sequence — sweep, then break — rather than by accumulated touches. ## How to measure it in your own data A definition you cannot test is a definition you have to take on trust. This is the shortest honest route from the concept to a number you computed yourself. - **Records you need** — Candle data at a declared timeframe, the order-block identification rule, a stated sweep test for the prior extreme, the structure-break definition, and the boundary election for the flipped zone. - **What you compute** — Track order blocks; flag as breakers those consumed by a move that (1) swept a qualifying prior high or low under the stated test and (2) closed through the block breaking structure. Grade revisits of the flipped zone by the declared touch rule — against matched neutral zones if the flip is ever to be claimed rather than narrated. - **What the answer tells you** — The sequence, in order: a raid through a prior extreme, a reversal that closes through the block which had defined the old direction, structure giving way — then a later return trading into the dead zone from the other side. The taught picture ends with a reaction there; how often it does is the unmeasured part. ## Questions and answers ### What is a breaker block? A failed order block with a specific death certificate: the move that consumed it first swept a prior high or low, then closed through the block and broke structure. The taxonomy re-registers the zone in the opposite role and expects revisits to react there. ### What is the difference between a breaker block and a mitigation block? The sweep. Both are failed order blocks expected to work in reverse; the breaker's consuming move raided a prior extreme first, the mitigation block's came from a plain failure swing. One construction detail, two names, and a taught ranking between them that no measurement on this page underwrites. ### How do you identify a breaker block step by step? Identify an order block under a stated rule; watch for a move that sweeps a qualifying prior extreme, then closes through the block with a structure break; re-draw the block's zone — range or body, per the stated election — in the flipped role. Every step carries a parameter, which is what makes the object reproducible. ### Do breaker blocks work? The testable form: do revisits of swept-then-broken blocks react differently from revisits of matched neutral zones — and from unswept failures? The construction above is precise enough to run that test; the sources that teach the object have not, and this page does not pretend otherwise. ## Where it sits in the ICT sequence The ICT vocabulary in the order the method is taught, with a step for each kind of object. - **Step** — 06 of 08 [Blocks](https://hadalinstruments.com/ict/#step-blocks): the candles that mark a return zone, and what became of them - **Also at this step** — [Order block](https://hadalinstruments.com/glossary/order-block/), [Mitigation block](https://hadalinstruments.com/glossary/mitigation-block/), [Rejection block](https://hadalinstruments.com/glossary/rejection-block/), [Propulsion block](https://hadalinstruments.com/glossary/propulsion-block/) - **Before it** — [Order block](https://hadalinstruments.com/glossary/order-block/) Blocks - **After it** — [Mitigation block](https://hadalinstruments.com/glossary/mitigation-block/) Blocks - **Every step** — [The ICT vocabulary map, with every term defined](https://hadalinstruments.com/ict/#vocabulary) ## The shape, drawn The smallest arrangement the definition admits. It is a drawing of a rule, not a reading of a market — nothing here is measured, and the table below it is the authoritative version. FIG. 01 ILLUSTRATIVE - The order block: the last candle closing against the move that follows. - The prior extreme. The consuming move sweeps through it first — the sweep is what separates a breaker from a mitigation block. - The block’s range, carried forward in its flipped role once the break consumes it. The breaker’s origin story, in order: a block forms, the move that consumes it first sweeps a prior extreme, then breaks structure through the block — after which the failed zone is drawn in its flipped role. Ordering the events establishes what makes a breaker a breaker rather than a mere failure. It does not establish that the flipped zone holds.
