Order blocks do not always hold. When price breaks straight through one instead of reacting, that failure creates a new type of zone — a breaker block. Understanding what happens after an order block fails is just as important as identifying the original block.
What Is a Breaker Block?
A breaker block forms when price breaks through a bullish order block that was supposed to hold as support, or through a bearish order block that was supposed to hold as resistance. The broken zone then flips polarity: a failed bullish order block can become resistance on a later retest, and a failed bearish order block can become support.
What Is a Mitigation Block?
A mitigation block is closely related but forms slightly differently: it is the last opposing candle before a structural shift, where price later returns only partway into the zone — mitigating some of the remaining orders — before reversing again in the original direction of the break.
| Concept | Formation | Typical use |
|---|---|---|
| Order Block | Last opposite candle before a strong impulse | Entry on first return to the zone |
| Breaker Block | Order block that price has fully broken through | Entry on retest after polarity flip |
| Mitigation Block | Last candle before a shift, only partly retraced into | Entry on shallow pullback before continuation |
Why Breakers Flip Polarity
The logic mirrors classic support-and-resistance flips. Traders who bought at the old order block, expecting it to hold, are now trapped in losing positions once price breaks through. When price returns to that level later, those trapped traders often sell to break even, adding fresh selling pressure that reinforces the new resistance.
Steps to Trade a Breaker Block
- 1.Identify an order block that gets fully broken with a strong displacement candle.
- 2.Mark that broken zone as a potential breaker block.
- 3.Wait for price to return to the breaker on a pullback.
- 4.Enter in the new direction, with a stop beyond the far edge of the breaker.
A breaker block is far more reliable when the break that created it also caused a genuine market structure shift, not just a temporary spike.
Choppy, low-momentum breaks often fail to hold as breaker blocks. Look for clean, decisive breaks with follow-through before trusting the flipped zone.
Putting It Together
Mitigation and breaker blocks remind traders that SMC zones are not static forever — they evolve as the market reveals new information. Watching how a zone behaves when tested a second time often tells you more about the market's real intent than the original formation did.
