KEY FINDINGS
|
|
================================================================================
|
|
|
|
✅ 2024-01-03: STRONG TRENDING DAY (DOWN)
|
|
• Best for trending regime detection tests
|
|
• Trend correlation: -0.93 (very strong)
|
|
• Consistent directional movement
|
|
|
|
✅ 2024-01-04 & 2024-01-05: RANGING DAYS
|
|
• Best for ranging regime detection tests
|
|
• Tight price ranges (0.83% - 1.23%)
|
|
• Low volatility, mean-reverting
|
|
|
|
⚠️ 2024-01-02: DATA QUALITY ISSUE
|
|
• Contains $36.05 outlier (should be ~$4800)
|
|
• Review/filter before production use
|
|
• Good for testing data quality filters
|
|
|
|
❌ NO HIGH-VOLATILITY DAYS IN SAMPLE
|
|
• All new days show low volatility (<0.01)
|
|
• Consider downloading Feb 2024 if volatile regime tests needed
|
