What Is a Failed Structure?
A failed structure occurs when the market forms a new structural high or low — appearing to continue the trend — but cannot sustain the level. Instead of confirming the breakout, price reverses and moves back through the broken level. This failure indicates that the side driving the breakout lacked the conviction or capital to hold price at the new level.
Failed structures frequently occur in conjunction with stop runs: price is pushed beyond a key level to sweep liquidity resting there, and then reverses. Recognizing this pattern allows traders to position on the side of the stronger market participants.
In trading, the failed structure is one of the most reliable reversal signals because it reveals the weakness of the dominant side in real time.
