Candlestick Patterns

Rickshaw Man

Introduction

Create a new Rickshaw Man candlestick pattern to indicate the pattern's presence.

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

Using RickshawMan Indicator

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

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

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

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

The following reference table describes the RickshawMan method:

RickshawMan()1/1

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

Creates a new RickshawMan 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 RickshawMan 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 RickshawManAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private RickshawMan _rickshawman;

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

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

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

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

public class RickshawManAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private RickshawMan _rickshawman;

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

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

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

The following reference table describes the RickshawMan constructor:

RickshawMan()1/2

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

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

RickshawMan()2/2

            RickshawMan QuantConnect.Indicators.CandlestickPatterns.RickshawMan (
    
   )

Initializes a new instance of the RickshawMan class.
