# Aroon Indicator

## 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

## What's a good value?

| Range | Rating | What it means |
|---|---|---|
| Aroon Up > 70 | Strong Uptrend | Recent high, bullish momentum |
| Aroon Down > 70 | Strong Downtrend | Recent low, bearish momentum |
| Both < 50 | Consolidation | No clear trend, ranging market |
| Crossover | Trend Change | Potential reversal in progress |

## Real-world example

Aroon Up at 92 and Aroon Down at 20 signals a strong uptrend with a recent high.
