Relative Moving Average

Introduction

This indicator represents the relative moving average indicator (RMA). RMA = SMA(3 x Period) - SMA(2 x Period) + SMA(1 x Period) per formula: https://www.hybrid-solutions.com/plugins/client-vtl-plugins/free/rma.html

To view the implementation of this indicator, see the LEAN GitHub repository.

Using RMA Indicator

To create an automatic indicators for RelativeMovingAverage, call the RMA helper method from the QCAlgorithm class. The RMA method creates a RelativeMovingAverage 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 Initializeinitialize method.

public class RelativeMovingAverageAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private RelativeMovingAverage _rma;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _rma = RMA(_symbol, 20);
    }

    public override void OnData(Slice data)
    {
        if (_rma.IsReady)
        {
            // The current value of _rma is represented by itself (_rma)
            // or _rma.Current.Value
            Plot("RelativeMovingAverage", "rma", _rma);
            // Plot all properties of rma
            Plot("RelativeMovingAverage", "shortaverage", _rma.ShortAverage);
            Plot("RelativeMovingAverage", "mediumaverage", _rma.MediumAverage);
            Plot("RelativeMovingAverage", "longaverage", _rma.LongAverage);
        }
    }
}
class RelativeMovingAverageAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self._symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.rma = self.RMA(self.symbol, 20)

    def on_data(self, slice: Slice) -> None:
        if self.rma.IsReady:
            # The current value of self.rma is represented by self.rma.Current.Value
            self.plot("RelativeMovingAverage", "rma", self.rma.Current.Value)
            # Plot all attributes of self.rma
            self.plot("RelativeMovingAverage", "shortaverage", self.rma.ShortAverage.Current.Value)
            self.plot("RelativeMovingAverage", "mediumaverage", self.rma.MediumAverage.Current.Value)
            self.plot("RelativeMovingAverage", "longaverage", self.rma.LongAverage.Current.Value)

The following reference table describes the RMA method:

RMA()1/1

            RelativeMovingAverage QuantConnect.Algorithm.QCAlgorithm.RMA (
    Symbol                           symbol,
    Int32                            period,
    *Nullable<Resolution>      resolution,
    *Func<IBaseData, Decimal>  selector
   )

Creates a new Relative Moving Average indicator for the symbol. The indicator will be automatically updated on the given resolution.

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 RelativeMovingAverage 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 Updateupdate method with time/number pair or an IndicatorDataPoint. The indicator will only be ready after you prime it with enough data.

public class RelativeMovingAverageAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private RelativeMovingAverage _rma;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _rma = new RelativeMovingAverage(20);
    }

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGetValue(_symbol, out var bar))
        {      
            _rma.Update(bar.EndTime, bar.Close);
        }
   
        if (_rma.IsReady)
        {
            // The current value of _rma is represented by itself (_rma)
            // or _rma.Current.Value
            Plot("RelativeMovingAverage", "rma", _rma);
            // Plot all properties of rma
            Plot("RelativeMovingAverage", "shortaverage", _rma.ShortAverage);
            Plot("RelativeMovingAverage", "mediumaverage", _rma.MediumAverage);
            Plot("RelativeMovingAverage", "longaverage", _rma.LongAverage);
        }
    }
}
class RelativeMovingAverageAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self._symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.rma = RelativeMovingAverage(20)

    def on_data(self, slice: Slice) -> None:
        bar = slice.Bars.get(self.symbol)
        if bar:
            self.rma.Update(bar.EndTime, bar.Close)
        if self.rma.IsReady:
            # The current value of self.rma is represented by self.rma.Current.Value
            self.plot("RelativeMovingAverage", "rma", self.rma.Current.Value)
            # Plot all attributes of self.rma
            self.plot("RelativeMovingAverage", "shortaverage", self.rma.ShortAverage.Current.Value)
            self.plot("RelativeMovingAverage", "mediumaverage", self.rma.MediumAverage.Current.Value)
            self.plot("RelativeMovingAverage", "longaverage", self.rma.LongAverage.Current.Value)

To register a manual indicator for automatic updates with the security data, call the RegisterIndicator method.

public class RelativeMovingAverageAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private RelativeMovingAverage _rma;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _rma = new RelativeMovingAverage(20);
        RegisterIndicator(_symbol, _rma, Resolution.Daily);
    }

    public override void OnData(Slice data)
    {
        if (_rma.IsReady)
        {
            // The current value of _rma is represented by itself (_rma)
            // or _rma.Current.Value
            Plot("RelativeMovingAverage", "rma", _rma);
            // Plot all properties of rma
            Plot("RelativeMovingAverage", "shortaverage", _rma.ShortAverage);
            Plot("RelativeMovingAverage", "mediumaverage", _rma.MediumAverage);
            Plot("RelativeMovingAverage", "longaverage", _rma.LongAverage);
        }
    }
}
class RelativeMovingAverageAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self._symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.rma = RelativeMovingAverage(20)
        self.RegisterIndicator(self.symbol, self.rma, Resolution.Daily)

    def on_data(self, slice: Slice) -> None:
        if self.rma.IsReady:
            # The current value of self.rma is represented by self.rma.Current.Value
            self.plot("RelativeMovingAverage", "rma", self.rma.Current.Value)
            # Plot all attributes of self.rma
            self.plot("RelativeMovingAverage", "shortaverage", self.rma.ShortAverage.Current.Value)
            self.plot("RelativeMovingAverage", "mediumaverage", self.rma.MediumAverage.Current.Value)
            self.plot("RelativeMovingAverage", "longaverage", self.rma.LongAverage.Current.Value)

The following reference table describes the RelativeMovingAverage constructor:

    string  name,
    int     period
   )
