Supported Indicators
Triangular Moving Average
Introduction
This indicator computes the Triangular Moving Average (TRIMA). The Triangular Moving Average is calculated with the following formula: (1) When the period is even, TRIMA(x,period)=SMA(SMA(x,period/2),(period/2)+1) (2) When the period is odd, TRIMA(x,period)=SMA(SMA(x,(period+1)/2),(period+1)/2)
To view the implementation of this indicator, see the LEAN GitHub repository.
Using TRIMA Indicator
To create an automatic indicators for TriangularMovingAverage
, call the TRIMA
helper method from the QCAlgorithm
class. The TRIMA
method creates a TriangularMovingAverage
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 TriangularMovingAverageAlgorithm : QCAlgorithm { private Symbol _symbol; private TriangularMovingAverage _trima; public override void Initialize() { _symbol = AddEquity("SPY", Resolution.Daily).Symbol; _trima = TRIMA(_symbol, 20); } public override void OnData(Slice data) { if (_trima.IsReady) { // The current value of _trima is represented by itself (_trima) // or _trima.Current.Value Plot("TriangularMovingAverage", "trima", _trima); } } }
class TriangularMovingAverageAlgorithm(QCAlgorithm): def Initialize(self) -> None: self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol self.trima = self.TRIMA(self.symbol, 20) def OnData(self, slice: Slice) -> None: if self.trima.IsReady: # The current value of self.trima is represented by self.trima.Current.Value self.Plot("TriangularMovingAverage", "trima", self.trima.Current.Value)
The following reference table describes the TRIMA
method:
TRIMA()1/1
TriangularMovingAverage QuantConnect.Algorithm.QCAlgorithm.TRIMA (Symbol
symbol,Int32
period,*Nullable<Resolution>
resolution,*Func<IBaseData, Decimal>
selector )
Creates a new TriangularMovingAverage indicator.
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 TriangularMovingAverage
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 time/number pair, or an IndicatorDataPoint
. The indicator will only be ready after you prime it with enough data.
public class TriangularMovingAverageAlgorithm : QCAlgorithm { private Symbol _symbol; private TriangularMovingAverage _trima; public override void Initialize() { _symbol = AddEquity("SPY", Resolution.Daily).Symbol; _trima = new TriangularMovingAverage(20); } public override void OnData(Slice data) { if (data.Bars.TryGeValue(_symbol, out var bar)) { _trima.Update(bar.EndTime, bar.Close); } if (_trima.IsReady) { // The current value of _trima is represented by itself (_trima) // or _trima.Current.Value Plot("TriangularMovingAverage", "trima", _trima); } } }
class TriangularMovingAverageAlgorithm(QCAlgorithm): def Initialize(self) -> None: self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol self.trima = TriangularMovingAverage(20) def OnData(self, slice: Slice) -> None: bar = slice.Bars.get(self.symbol) if bar: self.trima.Update(bar.EndTime, bar.Close) if self.trima.IsReady: # The current value of self.trima is represented by self.trima.Current.Value self.Plot("TriangularMovingAverage", "trima", self.trima.Current.Value)
To register a manual indicator for automatic updates with the security data, call the RegisterIndicator
method.
public class TriangularMovingAverageAlgorithm : QCAlgorithm { private Symbol _symbol; private TriangularMovingAverage _trima; public override void Initialize() { _symbol = AddEquity("SPY", Resolution.Daily).Symbol; _trima = new TriangularMovingAverage(20); RegisterIndicator(_symbol, _trima, Resolution.Daily); } public override void OnData(Slice data) { if (_trima.IsReady) { // The current value of _trima is represented by itself (_trima) // or _trima.Current.Value Plot("TriangularMovingAverage", "trima", _trima); } } }
class TriangularMovingAverageAlgorithm(QCAlgorithm): def Initialize(self) -> None: self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol self.trima = TriangularMovingAverage(20) self.RegisterIndicator(self.symbol, self.trima, Resolution.Daily) def OnData(self, slice: Slice) -> None: if self.trima.IsReady: # The current value of self.trima is represented by self.trima.Current.Value self.Plot("TriangularMovingAverage", "trima", self.trima.Current.Value)
