Candlestick Patterns

Thrusting

Introduction

Create a new Thrusting candlestick pattern indicator to indicate the pattern's presence.

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

Using Thrusting Indicator

To create an automatic indicators for Thrusting, call the Thrusting helper method from the QCAlgorithm class. The Thrusting method creates a Thrusting 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 ThrustingAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private Thrusting _thrusting;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _thrusting = CandlestickPatterns.Thrusting(_symbol);
    }

    public override void OnData(Slice data)
    {
        if (_thrusting.IsReady)
        {
            // The current value of _thrusting is represented by itself (_thrusting)
            // or _thrusting.Current.Value
            Plot("Thrusting", "thrusting", _thrusting);
            
        }
    }
}
class ThrustingAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.thrusting = self.CandlestickPatterns.Thrusting(self.symbol)

    def OnData(self, slice: Slice) -> None:
        if self.thrusting.IsReady:
            # The current value of self.thrusting is represented by self.thrusting.Current.Value
            self.Plot("Thrusting", "thrusting", self.thrusting.Current.Value)
            

The following reference table describes the Thrusting method:

Thrusting()1/1

            Thrusting QuantConnect.Algorithm.CandlestickPatterns.Thrusting (
    Symbol                                symbol,
    *Nullable<Decimal>              resolution,
    *Func<IBaseData, IBaseDataBar>  selector
   )
        

Creates a new Thrusting pattern indicator. 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 Thrusting 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. The indicator will only be ready after you prime it with enough data.

public class ThrustingAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private Thrusting _thrusting;

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

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGetValue(_symbol, out var bar))
        {      
            _thrusting.Update(bar);
        }
    
        if (_thrusting.IsReady)
        {
            // The current value of _thrusting is represented by itself (_thrusting)
            // or _thrusting.Current.Value
            Plot("Thrusting", "thrusting", _thrusting);
            
        }
    }
}
class ThrustingAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.thrusting = Thrusting()

    def OnData(self, slice: Slice) -> None:
        bar = slice.Bars.get(self.symbol)
        if bar:
            self.thrusting.Update(bar)
                
        if self.thrusting.IsReady:
            # The current value of self.thrusting is represented by self.thrusting.Current.Value
            self.Plot("Thrusting", "thrusting", self.thrusting.Current.Value)
            

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

public class ThrustingAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private Thrusting _thrusting;

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

    public override void OnData(Slice data)
    {
        if (_thrusting.IsReady)
        {
            // The current value of _thrusting is represented by itself (_thrusting)
            // or _thrusting.Current.Value
            Plot("Thrusting", "thrusting", _thrusting);
            
        }
    }
}
class ThrustingAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.thrusting = Thrusting()
        self.RegisterIndicator(self.symbol, self.thrusting, Resolution.Daily)

    def OnData(self, slice: Slice) -> None:
        if self.thrusting.IsReady:
            # The current value of self.thrusting is represented by self.thrusting.Current.Value
            self.Plot("Thrusting", "thrusting", self.thrusting.Current.Value)
            

The following reference table describes the Thrusting constructor:

Thrusting()1/2

            Thrusting QuantConnect.Indicators.CandlestickPatterns.Thrusting (
    string  name
   )
        

Initializes a new instance of the Thrusting class using the specified name.

Thrusting()2/2

            Thrusting QuantConnect.Indicators.CandlestickPatterns.Thrusting (
    
   )
        

Initializes a new instance of the Thrusting class.
