A failed opening range breakout is a qualified break that later meets the strategy’s written failure or invalidation condition. The chart shape alone is not a definition.
If a candle never satisfies the breakout rule, there was no qualified breakout to fail. Label it an unconfirmed attempt. This distinction keeps the denominator aligned with the strategy instead of counting every boundary touch as a trade.
Choose an observable failure rule
Possible rules include a close back inside the range, a close beyond the midpoint, a stop at the opposite edge, or a maximum time without continuation. Each definition produces a different failure count and cannot borrow another definition’s statistics.
Track double breaks separately
A session that qualifies above the range and later below it contains two directional events. Decide in advance whether the second break is a new setup, an automatic no-trade, or evidence that the first trade failed. Preserve the timestamps so simultaneous or same-candle events are handled consistently.
Do not turn failure into a reversal signal
A failed long breakout does not automatically predict a profitable short trade. A reversal strategy needs its own entry, stop, target, timing, and historical sample. Otherwise one observed failure is being used to justify an untested second strategy.
Use failure labels to improve review
Separate unconfirmed attempts, qualified failures, stopped trades, double breaks, late breaks, and no-trades. These labels explain how the rule behaved without implying that a filter can eliminate losses.
Educational use and risk
Historical patterns and target hit rates do not guarantee future results. This guide is general education, not personalized investment advice. Confirm market data with your broker and define risk before entering a trade.
