Step 2: Click "Scan for Patterns"
Find the Pattern Scanner Auto-Detect section and click the button.
Step 3: Review Results
The scanner returns up to 20 patterns, ranked by strength.
Understanding Pattern Results
Each pattern shows:
| Field | Meaning |
|---|---|
| Period | Start date → End date (e.g., Mar 12 → Aug 16) |
| Duration | Number of trading days |
| Probability | Historical win rate (80%+ is excellent) |
| Average Return | Expected return based on history |
| Strength Score | Combined metric (higher = better) |
Example: S&P 500 Top Pattern
#1 Ranked Pattern: March 12 → August 16
- Duration: 157 days
- Probability: 93.3%
- Average Return: +6.95%
- Strength: 6.48
This means holding S&P 500 from mid-March to mid-August has historically returned ~7% with 93% reliability.
Tips for Using the Scanner
✅ Look for 80%+ probability - Higher is more reliable ✅ Compare strength scores - Higher scores combine probability + return ✅ Check multiple timeframes - 10-year vs 15-year may differ ✅ Combine with current conditions - Use Market Regime filter
What NOT to Do
❌ Don't blindly follow patterns without other analysis ❌ Don't ignore low consistency scores ❌ Don't forget to check Year-over-Year comparison
