Candlestick Patterns

Separating Lines

Introduction

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

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

Using SeparatingLines Indicator

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

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _separatinglines = SeparatingLines(SPY);
    }

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

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

The following reference table describes the SeparatingLines method:

SeparatingLines()1/1

            SeparatingLines QuantConnect.Algorithm.CandlestickPatterns.SeparatingLines (
    Symbol                            symbol,
    *Nullable<Resolution>       resolution,
    *Func<IBaseData, TradeBar>  selector
   )

Creates a new SeparatingLines 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 SeparatingLines 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 SeparatingLinesAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private SeparatingLines _separatinglines;

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

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGeValue(_symbol, out var bar))
        {      
            _separatinglines.Update(bar);
        }

        if (_separatinglines.IsReady)
        {
            // The current value of _separatinglines is represented by itself (_separatinglines)
            // or _separatinglines.Current.Value
            Plot("SeparatingLines", "separatinglines", _separatinglines);
            
        }
    }
}
class SeparatingLinesAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.separatinglines = SeparatingLines(SPY)

    def OnData(self, slice: Slice) -> None:
        bar = slice.Bars.get(self.symbol)
        if bar:
            self.separatinglines.Update(bar)

        if self.separatinglines.IsReady:
            # The current value of self.separatinglines is represented by self.separatinglines.Current.Value
            self.Plot("SeparatingLines", "separatinglines", self.separatinglines.Current.Value)

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

public class SeparatingLinesAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private SeparatingLines _separatinglines;

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

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

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

The following reference table describes the SeparatingLines constructor:

SeparatingLines()1/2

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

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

SeparatingLines()2/2

            SeparatingLines QuantConnect.Indicators.CandlestickPatterns.SeparatingLines (
    
   )

Initializes a new instance of the SeparatingLine class.
