Three Outside

Introduction

Create a new Three Outside Up/Down candlestick pattern to indicate the pattern's presence.

Using ThreeOutside Indicator

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

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

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

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

The following reference table describes the ThreeOutside method:

ThreeOutside()1/1

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

Creates a new ThreeOutside 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 ThreeOutside 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 ThreeOutsideAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private ThreeOutside _threeoutside;

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

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

        if (_threeoutside.IsReady)
        {
            Plot("ThreeOutside", "threeoutside", _threeoutside);
        }
    }
}
class ThreeOutsideAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.threeoutside = ThreeOutside(SPY)

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

        if self.threeoutside.IsReady:
            self.Plot("ThreeOutside", "threeoutside", self.threeoutside.Current.Value)

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

public class ThreeOutsideAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private ThreeOutside _threeoutside;

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

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

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

The following reference table describes the ThreeOutside constructor:

ThreeOutside()1/2

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

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

ThreeOutside()2/2

            ThreeOutside QuantConnect.Indicators.CandlestickPatterns.ThreeOutside (
    
   )

Initializes a new instance of the ThreeOutsid class.
