Candlestick Patterns

Spinning Top

Introduction

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

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

Using SpinningTop Indicator

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

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

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

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

The following reference table describes the SpinningTop method:

SpinningTop()1/1

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

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

public class SpinningTopAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private SpinningTop _spinningtop;

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

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

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

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

public class SpinningTopAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private SpinningTop _spinningtop;

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

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

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

The following reference table describes the SpinningTop constructor:

SpinningTop()1/2

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

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

SpinningTop()2/2

            SpinningTop QuantConnect.Indicators.CandlestickPatterns.SpinningTop (
    
   )
        

Initializes a new instance of the SpinningTop class.
