Breaker Block
A breaker block is an order block that failed after a liquidity grab: price sweeps an obvious extreme (a new low or high), then reverses hard and breaks structure. The order block that triggered the trapped move then becomes flipped support or resistance — the traders trapped in the false breakout supply the fuel for the rejection on retest, ideally in confluence with an FVG. What sets it apart from a simple “broken support turned resistance” is the prior liquidity raid. What sets it apart from a mitigation block: here, an extreme was actually taken before the reversal. Full mechanics and retest strategy: the breaker block guide.
