Candlestick Patterns

In Neck

Introduction

Create a new In-Neck candlestick pattern indicator to indicate the pattern's presence.

Using InNeck Indicator

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

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

    public override void OnData(Slice data)
    {
        if (_inneck.IsReady)
        {
            Plot("InNeck", "inneck", _inneck);
        }
    }
}
class InNeckAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.inneck = self.InNeck(SPY)

    def OnData(self, slice: Slice) -> None:
        if self.inneck.IsReady:
            self.Plot("InNeck", "inneck", self.inneck.Current.Value)

The following reference table describes the InNeck method:

InNeck()1/1

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

Creates a new InNeck 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 InNeck 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 InNeckAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private InNeck _inneck;

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

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

        if (_inneck.IsReady)
        {
            Plot("InNeck", "inneck", _inneck);
        }
    }
}
class InNeckAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.inneck = InNeck(SPY)

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

        if self.inneck.IsReady:
            self.Plot("InNeck", "inneck", self.inneck.Current.Value)

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

public class InNeckAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private InNeck _inneck;

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

    public override void OnData(Slice data)
    {
        if (_inneck.IsReady)
        {
            Plot("InNeck", "inneck", _inneck);
        }
    }
}
class InNeckAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.inneck = InNeck(SPY)
        self.RegisterIndicator(self.symbol, self.inneck, Resolution.Daily)

    def OnData(self, slice: Slice) -> None:
        if self.inneck.IsReady:
            self.Plot("InNeck", "inneck", self.inneck.Current.Value)

The following reference table describes the InNeck constructor:

InNeck()1/2

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

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

InNeck()2/2

            InNeck QuantConnect.Indicators.CandlestickPatterns.InNeck (
    
   )

Initializes a new instance of the InNec class.
