Aroon Indicator
The Aroon indicator is a technical indicator used to identify trend changes in the price of an asset, as well as the strength of that trend. It consists of two lines: Aroon Up and Aroon Down.
Calculation
The Aroon indicator measures the time between highs and the time between lows over a time period.
\text{Aroon Up} = \frac{\text{Period} - \text{Days Since Period High}}{\text{Period}} \times 100
\text{Aroon Down} = \frac{\text{Period} - \text{Days Since Period Low}}{\text{Period}} \times 100
\text{Aroon Oscillator} = \text{Aroon Up} - \text{Aroon Down}
Where:
- Period: The lookback period (typically 25).
- Days Since Period High: The number of days since the highest high within the period.
- Days Since Period Low: The number of days since the lowest low within the period.
Interpretation
- Aroon Up: Measures the strength of the uptrend. Values close to 100 indicate a strong uptrend, while values close to 0 indicate a weak uptrend.
- Aroon Down: Measures the strength of the downtrend. Values close to 100 indicate a strong downtrend, while values close to 0 indicate a weak downtrend.
- Crossovers: When Aroon Up crosses above Aroon Down, it signals a potential uptrend. When Aroon Down crosses above Aroon Up, it signals a potential downtrend.
- Extremes: Values above 70 indicate a strong trend, while values below 30 indicate a weak trend.
Usage
C# code
using QuanTAlib;
// Create Aroon with period 14
var aroon = new Aroon(14);
// Update with a TBar
var bar = new TBar(DateTime.UtcNow, 100, 105, 95, 102, 1000);
var result = aroon.Update(bar);
// Access values
var osc = result.Value;
var up = aroon.Up.Value;
var down = aroon.Down.Value;
Console.WriteLine($"Aroon Osc: {osc:F2}, Up: {up:F2}, Down: {down:F2}");
Quantower
The Aroon indicator is available in Quantower as "Aroon".
- Period: The lookback period (default: 14).
- Show cold values: Whether to show values before the indicator is fully warmed up.
