A failed order block that flips polarity — old support becomes new resistance (or vice versa).
A Breaker Block is an order block that price traded through, which then flips its role: a bullish OB that gets broken becomes resistance on the retest; a bearish OB that gets broken becomes support. The logic: traders who entered at the original OB are now underwater, and when price returns to their entry, they exit at breakeven — creating the reaction. Breakers are premium Retrace zones because they combine structure (the break) with order flow (the trapped traders).
The best levels are the ones where someone's trapped. Breaker blocks mark exactly where the trapped money is waiting to get out.
Bullish OB at 5,835 fails as price crashes through to 5,820. When price rallies back to 5,835, the trapped longs sell at breakeven. The old support becomes the ceiling. Short the retest.
