◆ The PatternAroon Up = ((25 − periods since 25-period high) / 25) × 100.
The Aroon Indicator — Tushar Chande (1995). "Aroon" means "dawn" in Sanskrit.
Aroon Up = ((25 − periods since 25-day high) / 25) × 100
Aroon Down = ((25 − periods since 25-day low) / 25) × 100
Aroon Down = ((25 − periods since 25-day low) / 25) × 100
Interpretation:
• Aroon Up > 70, Down < 30 → strong uptrend
• Aroon Down > 70, Up < 30 → strong downtrend
• Both below 50 → consolidation
• Crossovers signal trend changes
• Aroon Up > 70, Down < 30 → strong uptrend
• Aroon Down > 70, Up < 30 → strong downtrend
• Both below 50 → consolidation
• Crossovers signal trend changes
