An order block is supposed to hold. When it fails, meaning price closes decisively through it, the zone does not simply vanish. Many traders treat the failed block as a breaker, a zone that now acts in the opposite direction on a retest. For example, a bullish order block that gets broken to the downside may become resistance when price returns to it from below. The reasoning is that traders who bought at that zone are now trapped and may exit near breakeven on the retest, adding selling pressure. It is a useful idea, but it needs conditions. The break should be displacement, not a slow drift. It should break structure as well, not just poke through the zone. And the retest should come with a clear reaction rather than a messy chop. I also note that breakers are most reliable when they form after a sweep of liquidity, since that suggests the original move was a trap. Without those conditions, a failed zone is just a failed zone, and trading it as a breaker is wishful thinking. Treat it as a candidate and demand confirmation.

The trapped buyers logic makes sense, but the condition about displacement is doing most of the work. Logic suggests a breaker formed by a slow drift through the block traps far fewer traders than one formed by a sharp break, so it should behave closer to a coin flip. That is easy to check: tag each breaker as drift or displacement, and record how many hours passed before the retest. A retest days later probably happens in a different context, so I would expect those to matter least, but the log will tell you.
