Candlestick Patterns

Up Down Gap Three Methods

Introduction

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

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

Using UpDownGapThreeMethods Indicator

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

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

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

    def on_data(self, slice: Slice) -> None:
        if self.updowngapthreemethods.IsReady:
            # The current value of self.updowngapthreemethods is represented by self.updowngapthreemethods.Current.Value
            self.plot("UpDownGapThreeMethods", "updowngapthreemethods", self.updowngapthreemethods.Current.Value)

The following reference table describes the UpDownGapThreeMethods method:

UpDownGapThreeMethods()1/1

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

Creates a new UpDownGapThreeMethods 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 UpDownGapThreeMethods 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 UpDownGapThreeMethodsAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private UpDownGapThreeMethods _updowngapthreemethods;

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

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

    def on_data(self, slice: Slice) -> None:
        bar = slice.Bars.get(self.symbol)
        if bar:
            self.updowngapthreemethods.Update(bar)
        if self.updowngapthreemethods.IsReady:
            # The current value of self.updowngapthreemethods is represented by self.updowngapthreemethods.Current.Value
            self.plot("UpDownGapThreeMethods", "updowngapthreemethods", self.updowngapthreemethods.Current.Value)

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

public class UpDownGapThreeMethodsAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private UpDownGapThreeMethods _updowngapthreemethods;

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

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

    def on_data(self, slice: Slice) -> None:
        if self.updowngapthreemethods.IsReady:
            # The current value of self.updowngapthreemethods is represented by self.updowngapthreemethods.Current.Value
            self.plot("UpDownGapThreeMethods", "updowngapthreemethods", self.updowngapthreemethods.Current.Value)

The following reference table describes the UpDownGapThreeMethods constructor:

UpDownGapThreeMethods()1/2

            UpDownGapThreeMethods QuantConnect.Indicators.CandlestickPatterns.UpDownGapThreeMethods (
