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

Create Manual 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. The following reference table describes the PivotPointsHighLow constructor.

PivotPointsHighLow()1/3

            PivotPointsHighLow QuantConnect.Indicators.PivotPointsHighLow (
     int   surroundingBarsCount,
     *int  lastStoredValues
   )

Creates a new instance of PivotPointsHighLow indicator with an equal high and low length.

PivotPointsHighLow()2/3

            PivotPointsHighLow QuantConnect.Indicators.PivotPointsHighLow (
     int   surroundingBarsCountForLowPoint,
     *int  lastStoredValues
   )

Creates a new instance of PivotPointsHighLow indicator.

PivotPointsHighLow()3/3

            PivotPointsHighLow QuantConnect.Indicators.PivotPointsHighLow (
     string  name,
     int     surroundingBarsCountForLowPoint,
     *int    lastStoredValues
   )

Creates a new instance of PivotPointsHighLow indicator.

Update Manual Indicators

You can update the indicator automatically or manually.

Automatic Update

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


private PivotPointsHighLow _pphl;

// In Initialize()
_pphl = new PivotPointsHighLow(name, surroundingBarsCountForHighPoint, surroundingBarsCountForLowPoint, surroundingBarsCount);
_pphl.Updated += IndicatorUpdateMethod;

RegisterIndicator(symbol, _pphl, Resolution.Daily);

// In IndicatorUpdateMethod()
if (_pphl.IsReady)
{
    var indicatorValue = _pphl.Current.Value;
}
    
# In Initialize()
self.pphl = PivotPointsHighLow(name, surroundingBarsCountForHighPoint, surroundingBarsCountForLowPoint, surroundingBarsCount)
self.pphl.Updated += self.IndicatorUpdateMethod

self.RegisterIndicator(symbol, self.pphl, Resolution.Daily)

# In IndicatorUpdateMethod()
if self.pphl.IsReady:
    indicator_value = self.pphl.Current.Value

To customize the data that automatically updates the indicator, see Custom Indicator Periods and Custom Indicator Values.

Manual Update

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/decimal pair. The indicator will only be ready after you prime it with enough data.

    
private PivotPointsHighLow _pphl;
private Symbol symbol;

// In Initialize()
_pphl = new PivotPointsHighLow(surroundingBarsCountForHighPoint, surroundingBarsCountForLowPoint, surroundingBarsCount);
symbol = AddEquity("SPY").Symbol;

// In OnData()
if (data.ContainsKey(_symbol))
{
    _pphl.Update(data[symbol].EndTime, data[symbol].High);
}
if (_pphl.IsReady)
{
    var indicatorValue = _pphl.Current.Value;
}
    
# In Initialize()
self.pphl = PivotPointsHighLow(surroundingBarsCountForHighPoint, surroundingBarsCountForLowPoint, surroundingBarsCount)
self.symbol = self.AddEquity("SPY").Symbol

# In OnData()
if data.ContainsKey(self.symbol):
    self.pphl.Update(data[self.symbol].EndTime, data[self.symbol].High)
if self.pphl.IsReady:
    indicator_value = self.pphl.Current.Value

Create Automatic Indicators

The PPHL method creates an PivotPointsHighLow indicator, sets up a consolidator to update the indicator, and then returns the indicator so you can use it in your algorithm.

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 defauls 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.

Get Indicator Values

To get the value of the indicator, use its Current.Value attribute.

private PivotPointsHighLow _pphl;

// In Initialize()
var symbol = AddEquity("SPY").Symbol;
_pphl = PPHL(symbol, lengthHigh, lengthLow);

// In OnData()
if (_pphl.IsReady)
{
    var current = _pphl.Current.Value;
}
# In Initialize()
symbol = self.AddEquity("SPY").Symbol
self.pphl = self.PPHL(symbol, lengthHigh, lengthLow)

# In OnData()
if self.pphl.IsReady:
    current = self.pphl.Current.Value

Visualization

To plot indicator values, in the OnData event handler, call the Plot method.

private PivotPointsHighLow _pphl;

// In Initialize()
var symbol = AddEquity("SPY").Symbol;
_pphl = PPHL(symbol, lengthHigh, lengthLow);

// In OnData()
if (_pphl.IsReady)
{
    Plot("My Indicators", "pivotpointshighlow", _pphl.Current);
}
# In Initialize()
symbol = self.AddEquity("SPY").Symbol
self.pphl = self.PPHL(symbol, lengthHigh, lengthLow)

# In OnData()
if self.pphl.IsReady:
    self.Plot("My Indicators", "pivotpointshighlow", self.pphl.Current)
