What is Aroon?
Identifies when trends are likely to start and measures their strength by tracking time since highest high and lowest low.
Think of it like this
Like tracking how many days since your best and worst golf games - the more recent either is, the stronger that trend.
Formula
Aroon Up/Down = ((Period - Days Since High/Low) ÷ Period) × 100- Aroon Up: Days since highest high relative to period
- Aroon Down: Days since lowest low relative to period
- Oscillator: Aroon Up - Aroon Down
Why it matters
- Identifies emerging trends early
- Shows trend strength and potential reversals
- Oscillator shows net trend direction
- Good for timing entry points
