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 indicator for RelativeMovingAverage, call the RMArma helper method from the QCAlgorithm class. The RMArma 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 abands
            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.add_equity("SPY", Resolution.DAILY).symbol
        self._rma = self.rma(self._symbol, 20)

    def on_data(self, slice: Slice) -> None:

        if self._rma.is_ready:
            # 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", "short_average", self._rma.short_average.current.value)
            self.plot("RelativeMovingAverage", "medium_average", self._rma.medium_average.current.value)
            self.plot("RelativeMovingAverage", "long_average", self._rma.long_average.current.value)

For more information about this method, see the QCAlgorithm classQCAlgorithm class.

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. The indicator will only be ready after you prime it with enough data.

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

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

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGetValue(_symbol, out var bar))
            _relativemovingaverage.Update(bar.EndTime, bar.Close);

        if (_relativemovingaverage.IsReady)
        {
            // The current value of _relativemovingaverage is represented by itself (_relativemovingaverage)
            // or _relativemovingaverage.Current.Value
            Plot("RelativeMovingAverage", "relativemovingaverage", _relativemovingaverage);
            // Plot all properties of abands
            Plot("RelativeMovingAverage", "shortaverage", _relativemovingaverage.ShortAverage);
            Plot("RelativeMovingAverage", "mediumaverage", _relativemovingaverage.MediumAverage);
            Plot("RelativeMovingAverage", "longaverage", _relativemovingaverage.LongAverage);
        }
    }
}
class RelativeMovingAverageAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._relativemovingaverage = RelativeMovingAverage(20)

    def on_data(self, slice: Slice) -> None:
        bar = slice.bars.get(self._symbol)
        if bar:
            self._relativemovingaverage.update(bar.end_time, bar.close)

        if self._relativemovingaverage.is_ready:
            # The current value of self._relativemovingaverage is represented by self._relativemovingaverage.current.value
            self.plot("RelativeMovingAverage", "relativemovingaverage", self._relativemovingaverage.current.value)
            # Plot all attributes of self._relativemovingaverage
            self.plot("RelativeMovingAverage", "short_average", self._relativemovingaverage.short_average.current.value)
            self.plot("RelativeMovingAverage", "medium_average", self._relativemovingaverage.medium_average.current.value)
            self.plot("RelativeMovingAverage", "long_average", self._relativemovingaverage.long_average.current.value)

Indicator History

To get the historical data of the RelativeMovingAverage indicator, call the IndicatorHistoryself.indicator_history method. This method resets your indicator, makes a history request, and updates the indicator with the historical data. Just like with regular history requests, the IndicatorHistoryindicator_history method supports time periods based on a trailing number of bars, a trailing period of time, or a defined period of time. If you don't provide a resolution argument, it defaults to match the resolution of the security subscription. 

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

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

        var indicatorHistory = IndicatorHistory(_rma, _symbol, 100, Resolution.Minute);
        var timeSpanIndicatorHistory = IndicatorHistory(_rma, _symbol, TimeSpan.FromDays(10), Resolution.Minute);
        var timePeriodIndicatorHistory = IndicatorHistory(_rma, _symbol, new DateTime(2024, 7, 1), new DateTime(2024, 7, 5), Resolution.Minute);

        // Access all attributes of indicatorHistory
        var shortAverage = indicatorHistory.Select(x => ((dynamic)x).ShortAverage).ToList();
        var mediumAverage = indicatorHistory.Select(x => ((dynamic)x).MediumAverage).ToList();
        var longAverage = indicatorHistory.Select(x => ((dynamic)x).LongAverage).ToList();
    }
}
class RelativeMovingAverageAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._rma = self.rma(self._symbol, 20)

        indicator_history = self.indicator_history(self._rma, self._symbol, 100, Resolution.MINUTE)
        timedelta_indicator_history = self.indicator_history(self._rma, self._symbol, timedelta(days=10), Resolution.MINUTE)
        time_period_indicator_history = self.indicator_history(self._rma, self._symbol, datetime(2024, 7, 1), datetime(2024, 7, 5), Resolution.MINUTE)
    
        # Access all attributes of indicator_history
        indicator_history_df = indicator_history.data_frame
        short_average = indicator_history_df["shortaverage"]
        medium_average = indicator_history_df["mediumaverage"]
        long_average = indicator_history_df["longaverage"]
