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 indicator for PivotPointsHighLow, call the PPHLpphl helper method from the QCAlgorithm class. The PPHLpphl 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 Initializeinitialize 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.add_equity("SPY", Resolution.DAILY).symbol
self._pphl = self.pphl(self._symbol, 10, 10, 100)
def on_data(self, slice: Slice) -> None:
if self._pphl.is_ready:
# The current value of self._pphl is represented by self._pphl.current.value
self.plot("PivotPointsHighLow", "pphl", self._pphl.current.value)For more information about this method, see the QCAlgorithm classQCAlgorithm class.
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 Updateupdate method. The indicator will only be ready after you prime it with enough data.
public class PivotPointsHighLowAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private PivotPointsHighLow _pivotpointshighlow;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_pivotpointshighlow = new PivotPointsHighLow(10, 10, 100);
}
public override void OnData(Slice data)
{
if (data.Bars.TryGetValue(_symbol, out var bar))
_pivotpointshighlow.Update(bar);
if (_pivotpointshighlow.IsReady)
{
// The current value of _pivotpointshighlow is represented by itself (_pivotpointshighlow)
// or _pivotpointshighlow.Current.Value
Plot("PivotPointsHighLow", "pivotpointshighlow", _pivotpointshighlow);
}
}
} class PivotPointsHighLowAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._pivotpointshighlow = PivotPointsHighLow(10, 10, 100)
def on_data(self, slice: Slice) -> None:
bar = slice.bars.get(self._symbol)
if bar:
self._pivotpointshighlow.update(bar)
if self._pivotpointshighlow.is_ready:
# The current value of self._pivotpointshighlow is represented by self._pivotpointshighlow.current.value
self.plot("PivotPointsHighLow", "pivotpointshighlow", self._pivotpointshighlow.current.value)For more information about this indicator, see its referencereference.
Indicator History
To get the historical data of the PivotPointsHighLow indicator, call the IndicatorHistoryself.indicator_history method. This method resets your indicator, makes a history request, and updates the indicator with the historical data. Just like with regular history requests, the IndicatorHistoryindicator_history method supports time periods based on a trailing number of bars, a trailing period of time, or a defined period of time. If you don't provide a resolution argument, it defaults to match the resolution of the security subscription.

{
private Symbol _symbol;
private PivotPointsHighLow _pphl;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_pphl = PPHL(_symbol, 10, 10, 100);
var indicatorHistory = IndicatorHistory(_pphl, _symbol, 100, Resolution.Minute);
var timeSpanIndicatorHistory = IndicatorHistory(_pphl, _symbol, TimeSpan.FromDays(10), Resolution.Minute);
var timePeriodIndicatorHistory = IndicatorHistory(_pphl, _symbol, new DateTime(2024, 7, 1), new DateTime(2024, 7, 5), Resolution.Minute);
}

def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._pphl = self.pphl(self._symbol, 10, 10, 100)
indicator_history = self.indicator_history(self._pphl, self._symbol, 100, Resolution.MINUTE)
timedelta_indicator_history = self.indicator_history(self._pphl, self._symbol, timedelta(days=10), Resolution.MINUTE)
time_period_indicator_history = self.indicator_history(self._pphl, self._symbol, datetime(2024, 7, 1), datetime(2024, 7, 5), Resolution.MINUTE)
