Accumulation Distribution Oscillator
Introduction
This indicator computes the Accumulation/Distribution Oscillator (ADOSC) The Accumulation/Distribution Oscillator is calculated using the following formula: ADOSC = EMA(fast,AD) - EMA(slow,AD)
To view the implementation of this indicator, see the LEAN GitHub repository.
Using ADOSC Indicator
To create an automatic indicators for AccumulationDistributionOscillator, call the ADOSC helper method from the QCAlgorithm class. The ADOSC method creates a AccumulationDistributionOscillator 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 AccumulationDistributionOscillatorAlgorithm : QCAlgorithm
{
private Symbol _symbol;
private AccumulationDistributionOscillator _adosc;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
_adosc = ADOSC(_symbol, 10, 2);
}
public override void OnData(Slice data)
{
if (_adosc.IsReady)
{
// The current value of _adosc is represented by itself (_adosc)
// or _adosc.Current.Value
Plot("AccumulationDistributionOscillator", "adosc", _adosc);
}
}
} class AccumulationDistributionOscillatorAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
self._adosc = self.adosc(self._symbol, 10, 2)
def on_data(self, slice: Slice) -> None:
if self._adosc.is_ready:
# The current value of self._adosc is represented by self._adosc.current.value
self.plot("AccumulationDistributionOscillator", "adosc", self._adosc.current.value)
The following reference table describes the ADOSC method:
adosc(symbol, fast_period, slow_period, resolution=None, selector=None)[source]Creates a new AccumulationDistributionOscillator indicator.
- symbol (Symbol) — The symbol whose ADOSC we want
- fast_period (int) — The fast moving average period
- slow_period (int) — The slow moving average period
- resolution (Resolution, optional) — The resolution
- selector (Callable[IBaseData, TradeBar], optional) — x.Value)
The AccumulationDistributionOscillator indicator for the requested symbol over the specified period
ADOSC(symbol, fastPeriod, slowPeriod, resolution=None, selector=None)[source]Creates a new AccumulationDistributionOscillator indicator.
- symbol (Symbol) — The symbol whose ADOSC we want
- fastPeriod (Int32) — The fast moving average period
- slowPeriod (Int32) — The slow moving average period
- resolution (Resolution, optional) — The resolution
- selector (Func<IBaseData, TradeBar>, optional) — x.Value)
The AccumulationDistributionOscillator indicator for the requested symbol over the specified period
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 AccumulationDistributionOscillator 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 override void OnData(Slice data)
{
if (data.Bars.TryGetValue(_symbol, out var bar))
{
_adosc.Update(bar);
}
if (_adosc.IsReady)
{
// The current value of _adosc is represented by itself (_adosc)
// or _adosc.Current.Value
Plot("AccumulationDistributionOscillator", "adosc", _adosc);
}

self._adosc.update(bar)
if self._adosc.is_ready:
# The current value of self._adosc is represented by self._adosc.current.value
self.plot("AccumulationDistributionOscillator", "adosc", self._adosc.current.value)
To register a manual indicator for automatic updates with the security data, call the RegisterIndicatorregister_indicator method.

Indicator History
To get the historical data of the AccumulationDistributionOscillator 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 AccumulationDistributionOscillatorAlgorithm : QCAlgorithm
{
private Symbol _symbol;
public override void Initialize()
{
_symbol = AddEquity("SPY", Resolution.Daily).Symbol;
var adosc = ADOSC(_symbol, 10, 2);
var countIndicatorHistory = IndicatorHistory(adosc, _symbol, 100, Resolution.Minute);
var timeSpanIndicatorHistory = IndicatorHistory(adosc, _symbol, TimeSpan.FromDays(10), Resolution.Minute);
var timePeriodIndicatorHistory = IndicatorHistory(adosc, _symbol, new DateTime(2024, 7, 1), new DateTime(2024, 7, 5), Resolution.Minute);
}
} class AccumulationDistributionOscillatorAlgorithm(QCAlgorithm):
def initialize(self) -> None:
self._symbol = self.add_equity("SPY", Resolution.DAILY).symbol
adosc = self.adosc(self._symbol, 10, 2)
count_indicator_history = self.indicator_history(adosc, self._symbol, 100, Resolution.MINUTE)
timedelta_indicator_history = self.indicator_history(adosc, self._symbol, timedelta(days=10), Resolution.MINUTE)
time_period_indicator_history = self.indicator_history(adosc, self._symbol, datetime(2024, 7, 1), datetime(2024, 7, 5), Resolution.MINUTE)
To make the IndicatorHistoryindicator_history method update the indicator with an alternative price field instead of the close (or mid-price) of each bar, pass a selector argument.
var indicatorHistory = IndicatorHistory(adosc, 100, Resolution.Minute, (bar) => ((TradeBar)bar).High);
indicator_history = self.indicator_history(adosc, 100, Resolution.MINUTE, lambda bar: bar.high) indicator_history_df = indicator_history.data_frame
If you already have a list of Slice objects, you can pass them to the IndicatorHistoryindicator_history method to avoid the internal history request.
var history = History(_symbol, 100, Resolution.Minute); var historyIndicatorHistory = IndicatorHistory(adosc, history);
