Chaikin Oscillator

Introduction

This class is an alias for AccumulationDistributionOscillator (also known as Chaikin Oscillator).

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

Using CO Indicator

To create an automatic indicator for ChaikinOscillator, call the COco helper method from the QCAlgorithm class. The COco method creates a ChaikinOscillator 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 ChaikinOscillatorAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private ChaikinOscillator _co;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _co = CO(_symbol, 3, 10);
    }

    public override void OnData(Slice data)
    {

        if (_co.IsReady)
        {
            // The current value of _co is represented by itself (_co)
            // or _co.Current.Value
            Plot("ChaikinOscillator", "co", _co);
        }
    }
}
class ChaikinOscillatorAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._co = self.co(self._symbol, 3, 10)

    def on_data(self, slice: Slice) -> None:

        if self._co.is_ready:
            # The current value of self._co is represented by self._co.current.value
            self.plot("ChaikinOscillator", "co", self._co.current.value)

For more information about this method, see the QCAlgorithm classQCAlgorithm class.

You can manually create a ChaikinOscillator 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 ChaikinOscillatorAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private ChaikinOscillator _chaikinoscillator;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _chaikinoscillator = new ChaikinOscillator(3, 10);
    }

    public override void OnData(Slice data)
    {
        if (data.Bars.TryGetValue(_symbol, out var bar))
            _chaikinoscillator.Update(bar);

        if (_chaikinoscillator.IsReady)
        {
            // The current value of _chaikinoscillator is represented by itself (_chaikinoscillator)
            // or _chaikinoscillator.Current.Value
            Plot("ChaikinOscillator", "chaikinoscillator", _chaikinoscillator);
        }
    }
}
class ChaikinOscillatorAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._chaikinoscillator = ChaikinOscillator(3,10)

    def on_data(self, slice: Slice) -> None:
        bar = slice.bars.get(self._symbol)
        if bar:
            self._chaikinoscillator.update(bar)

        if self._chaikinoscillator.is_ready:
            # The current value of self._chaikinoscillator is represented by self._chaikinoscillator.current.value
            self.plot("ChaikinOscillator", "chaikinoscillator", self._chaikinoscillator.current.value)

Indicator History

To get the historical data of the ChaikinOscillator 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. 

public class ChaikinOscillatorAlgorithm : QCAlgorithm
{
    private Symbol _symbol;
    private ChaikinOscillator _co;

    public override void Initialize()
    {
        _symbol = AddEquity("SPY", Resolution.Daily).Symbol;
        _co = CO(_symbol, 3, 10);

        var indicatorHistory = IndicatorHistory(_co, _symbol, 100, Resolution.Minute);
        var timeSpanIndicatorHistory = IndicatorHistory(_co, _symbol, TimeSpan.FromDays(10), Resolution.Minute);
        var timePeriodIndicatorHistory = IndicatorHistory(_co, _symbol, new DateTime(2024, 7, 1), new DateTime(2024, 7, 5), Resolution.Minute);
    }
}
class ChaikinOscillatorAlgorithm(QCAlgorithm):
    def initialize(self) -> None:
        self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
        self._co = self.co(self._symbol, 3, 10)

        indicator_history = self.indicator_history(self._co, self._symbol, 100, Resolution.MINUTE)
        timedelta_indicator_history = self.indicator_history(self._co, self._symbol, timedelta(days=10), Resolution.MINUTE)
        time_period_indicator_history = self.indicator_history(self._co, self._symbol, datetime(2024, 7, 1), datetime(2024, 7, 5), Resolution.MINUTE)
