A Breaker Block is a specific type of order block that forms after a market structure break, indicating a shift in market sentiment. For example, if price breaks a significant support level and then retests a previous bullish order block, that block could become a bearish Breaker Block. A Breaker Block originates from a failed order block. If a bullish order block was expected to hold support but price aggressively breaks below it, that same block, upon retest from underneath, transforms into a bearish Breaker Block. Conversely, if a bearish order block was expected to hold resistance but price aggressively breaks above it, that block, upon retest from above, becomes a bullish Breaker Block. Traders look for price to return to this Breaker Block area after the market structure break, expecting it to act as new resistance (in a bearish scenario) or new support (in a bullish scenario). For instance, when GBP/JPY aggressively breaks below a key demand zone, moves lower, and then retraces back towards that broken demand zone, that zone now acts as a bearish Breaker Block, providing a high-probability short entry.
