A gallery containing only ideal winners trains recognition on clean hindsight. Failed breaks teach where apparent strength loses acceptance: above a prior high, into higher-timeframe supply, or after participation disappears.
Capture the chart in stages
Save one image before the break, one at the close outside the level, and one after resolution. Record what you knew at each stage. This guards against explaining the failure with information that arrived later.
Tag the failure
Useful tags include wick-only break, immediate close back in range, no volume expansion, late entry, obstacle overhead, and retest that cut too deeply. After twenty examples, count clusters—not to predict certainty, but to discover which conditions deserve a rule or further study.
The notebook should include avoided trades too. Passing on a weak setup is a decision worth reviewing even though it produces no profit-and-loss entry.
