Pivot Points High Low

Introduction

Pivot Points (High/Low), also known as Bar Count Reversals, indicator. https://www.fidelity.com/learning-center/trading-investing/technical-analysis/technical-indicator-guide/pivot-points-high-low

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

Using PPHL Indicator

To create an automatic indicators for PivotPointsHighLow, call the PPHL helper method from the QCAlgorithm class. The PPHL method creates a PivotPointsHighLow 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 PivotPointsHighLowAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private PivotPointsHighLow _pphl;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _pphl = PPHL(_symbol, 10, 10, 100);
    }

    public override void OnData(Slice data)
    {
        if (_pphl.IsReady)
        {
            // The current value of _pphl is represented by itself (_pphl)
            // or _pphl.Current.Value
            Plot("PivotPointsHighLow", "pphl", _pphl);
            
        }
    }
}
class PivotPointsHighLowAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.pphl = self.PPHL(self.symbol, 10, 10, 100)

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

The following reference table describes the PPHL method:

PPHL()1/1

            PivotPointsHighLow QuantConnect.Algorithm.QCAlgorithm.PPHL (
    Symbol                                symbol,
    Int32                                 lengthHigh,
    Int32                                 lengthLow,
    *Int32                                lastStoredValues,
    *Nullable<Resolution>           resolution,
    *Func<IBaseData, IBaseDataBar>  selector
   )
        

Creates a new PivotPointsHighLow indicator.

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 PivotPointsHighLow 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 time/number pair or an IndicatorDataPoint. The indicator will only be ready after you prime it with enough data.

public class PivotPointsHighLowAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private PivotPointsHighLow _pphl;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _pphl = new PivotPointsHighLow(10, 10, 100);
    }

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGetValue(_symbol, out var bar))
        {      
            _pphl.Update(bar.EndTime, bar.Close);
        }
   
        if (_pphl.IsReady)
        {
            // The current value of _pphl is represented by itself (_pphl)
            // or _pphl.Current.Value
            Plot("PivotPointsHighLow", "pphl", _pphl);
            
        }
    }
}
class PivotPointsHighLowAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.pphl = PivotPointsHighLow(10, 10, 100)

    def OnData(self, slice: Slice) -> None:
        bar = slice.Bars.get(self.symbol)
        if bar:
            self.pphl.Update(bar.EndTime, bar.Close)
        if self.pphl.IsReady:
            # The current value of self.pphl is represented by self.pphl.Current.Value
            self.Plot("PivotPointsHighLow", "pphl", self.pphl.Current.Value)
            

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

public class PivotPointsHighLowAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private PivotPointsHighLow _pphl;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _pphl = new PivotPointsHighLow(10, 10, 100);
        RegisterIndicator(_symbol, _pphl, Resolution.Daily);
    }

    public override void OnData(Slice data)
    {
        if (_pphl.IsReady)
        {
            // The current value of _pphl is represented by itself (_pphl)
            // or _pphl.Current.Value
            Plot("PivotPointsHighLow", "pphl", _pphl);
            
        }
    }
}
class PivotPointsHighLowAlgorithm(QCAlgorithm):
    def Initialize(self) -> None:
        self.symbol = self.AddEquity("SPY", Resolution.Daily).Symbol
        self.pphl = PivotPointsHighLow(10, 10, 100)
        self.RegisterIndicator(self.symbol, self.pphl, Resolution.Daily)

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