What is a breakout?
A breakout describes price moving beyond a previously defined range, support/resistance area or structural boundary.
The definition should be established before evaluating whether a breakout occurred.
Close, wick and acceptance
Some traders require a candle close beyond a level; others evaluate time spent beyond the area, volume or follow-through.
These are strategy rules, not universal definitions.
What is a retest?
After breaking an area, price may return toward it. Traders often observe whether the old boundary attracts renewed buying or selling.
Failed breakouts
Price can trade beyond a level and then rapidly return into the prior range. This is often called a failed breakout or false breakout.
Common mistakes
Entering every wick beyond a level
Temporary movement beyond a boundary can reverse quickly.
Assuming a retest must occur
Strong breakouts can continue without returning to the level.
Moving the breakout level after seeing the result
Retrospective adjustment creates hindsight bias.
A breakout needs an operational definition
Possible definitions include any trade beyond a level, a candle close beyond it, a minimum percentage or ATR distance, or sustained trading outside the prior area.
Different definitions produce different signal counts and results. The rule should therefore be fixed before performance is evaluated.
A retest is not guaranteed
After leaving a level, price may revisit the breakout area, continue without returning, or immediately fail back through it. Waiting for a retest can improve selectivity in some systems but can also cause valid moves to be missed.
A retest rule should define how close price must return, how long the setup remains valid and what constitutes rejection or acceptance.
Failed breakouts contain useful information but no certainty
A move beyond a boundary followed by a return inside the prior structure is often called a failed or false breakout. It shows that the attempted move did not maintain acceptance under the chosen definition.
That failure can provide context, but it does not guarantee a move toward the opposite side of the range.
Key takeaways
- Breakouts require a predefined structural boundary.
- Different strategies use different confirmation rules.
- A retest is a return toward the broken area, not a guaranteed event.
- Breakouts can fail and return into the prior structure.
