Aroon Oscillator
Introduction
The Aroon Oscillator is the difference between AroonUp and AroonDown. The value of this indicator fluctuates between -100 and +100. An upward trend bias is present when the oscillator is positive, and a negative trend bias is present when the oscillator is negative. AroonUp/Down values over 75 identify strong trends in their respective direction.
Using AROON Indicator
To create an automatic indicators for AroonOscillator, call the AROON helper method from the QCAlgorithm class. The AROON method creates a AroonOscillator object, hooks it up for automatic updates, and returns it so you can used it in your algorithm. In most cases, you should call the helper method in the Initialize method.
public class AroonOscillatorAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private AroonOscillator _aroon;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_aroon = AROON("SPY", 10, 20);
}
public override void OnData(Slice data)
{
if (_aroon.IsReady)
{
Plot("AroonOscillator", "aroon", _aroon);
Plot("AroonOscillator", "aroonup", _aroon.AroonUp);
Plot("AroonOscillator", "aroondown", _aroon.AroonDown);
}
}
} class AroonOscillatorAlgorithm(QCAlgorithm):
def Initialize(self) -> None:
self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
self.aroon = self.AROON("SPY", 10, 20)
def OnData(self, slice: Slice) -> None:
if self.aroon.IsReady:
self.Plot("AroonOscillator", "aroon", self.aroon.Current.Value)
self.Plot("AroonOscillator", "aroonup", self.aroon.AroonUp.Current.Value)
self.Plot("AroonOscillator", "aroondown", self.aroon.AroonDown.Current.Value)
The following reference table describes the AROON method:
AROON()1/2
AroonOscillator QuantConnect.Algorithm.QCAlgorithm.AROON (
Symbol symbol,
Int32 period,
*Nullable<Resolution> resolution,
*Func<IBaseData, IBaseDataBar> selector
)
Creates a new AroonOscillator indicator which will compute the AroonUp and AroonDown (as well as the delta).
AROON()2/2
AroonOscillator QuantConnect.Algorithm.QCAlgorithm.AROON (
Symbol symbol,
Int32 upPeriod,
Int32 downPeriod,
*Nullable<Resolution> resolution,
*Func<IBaseData, IBaseDataBar> selector
)
Creates a new AroonOscillator indicator which will compute the AroonUp and AroonDown (as well as the delta).
If you don't provide a resolution, it defaults to the security resolution. If you provide a resolution, it must be greater than or equal to the resolution of the security. For instance, if you subscribe to hourly data for a security, you should update its indicator with data that spans 1 hour or longer.
For more information about the selector argument, see Alternative Price Fields.
For more information about plotting indicators, see Plotting Indicators.
You can manually create a AroonOscillator indicator, so it doesn't automatically update. Manual indicators let you update their values with any data you choose.
Updating your indicator manually enables you to control when the indicator is updated and what data you use to update it. To manually update the indicator, call the Update method with a TradeBar, or QuoteBar. The indicator will only be ready after you prime it with enough data.
public class AroonOscillatorAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private AroonOscillator _aroon;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_aroon = new AroonOscillator(10, 20);
}
public override void OnData(Slice data)
{
if (data.Bars.TryGeValue(_symbol, out var bar))
{
_aroon.Update(bar);
}
if (_aroon.IsReady)
{
Plot("AroonOscillator", "aroon", _aroon);
Plot("AroonOscillator", "aroonup", _aroon.AroonUp);
Plot("AroonOscillator", "aroondown", _aroon.AroonDown);
}
}
} class AroonOscillatorAlgorithm(QCAlgorithm):
def Initialize(self) -> None:
self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
self.aroon = AroonOscillator(10, 20)
def OnData(self, slice: Slice) -> None:
bar = data.Bars.get(self.symbol)
if bar:
self.aroon.Update(bar)
if self.aroon.IsReady:
self.Plot("AroonOscillator", "aroon", self.aroon.Current.Value)
self.Plot("AroonOscillator", "aroonup", self.aroon.AroonUp.Current.Value)
self.Plot("AroonOscillator", "aroondown", self.aroon.AroonDown.Current.Value)
To register a manual indicator for automatic updates with the security data, call the RegisterIndicator method.
public class AroonOscillatorAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private AroonOscillator _aroon;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_aroon = new AroonOscillator(10, 20);
RegisterIndicator(_symbol, _aroon, Resolution.Daily);
}
public override void OnData(Slice data)
{
if (_aroon.IsReady)
{
Plot("AroonOscillator", "aroon", _aroon);
Plot("AroonOscillator", "aroonup", _aroon.AroonUp);
Plot("AroonOscillator", "aroondown", _aroon.AroonDown);
}
}
} class AroonOscillatorAlgorithm(QCAlgorithm):
def Initialize(self) -> None:
self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
self.aroon = AroonOscillator(10, 20)
self.RegisterIndicator(self.symbol, self.aroon, Resolution.Daily)
def OnData(self, slice: Slice) -> None:
if self.aroon.IsReady:
self.Plot("AroonOscillator", "aroon", self.aroon.Current.Value)
self.Plot("AroonOscillator", "aroonup", self.aroon.AroonUp.Current.Value)
self.Plot("AroonOscillator", "aroondown", self.aroon.AroonDown.Current.Value)
The following reference table describes the AroonOscillator constructor:
AroonOscillator()1/2
AroonOscillator QuantConnect.Indicators.AroonOscillator (
int upPeriod,
int downPeriod
)
Creates a new AroonOscillator from the specified up/down periods.
AroonOscillator()2/2
AroonOscillator QuantConnect.Indicators.AroonOscillator (
string name,
int upPeriod,
int downPeriod
)
Creates a new AroonOscillator from the specified up/down periods.
