- Read context and timeframe before the pattern.
- Write the entry condition and invalidation.
- Calculate size from permitted risk.
Evidence of validity
- Record the result without rewriting the plan.
- Separate observable evidence from interpretation.
- Define confirmation and invalidation together.
