# Supported Indicators

## Accumulation Distribution Oscillator

### Create Manual 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. The following reference table describes the AccumulationDistributionOscillator constructor.

### AccumulationDistributionOscillator()1/2

            AccumulationDistributionOscillator QuantConnect.Indicators.AccumulationDistributionOscillator (
int  slowPeriod
)


Initializes a new instance of the AccumulationDistributionOscillator class using the specified parameters.

### AccumulationDistributionOscillator()2/2

            AccumulationDistributionOscillator QuantConnect.Indicators.AccumulationDistributionOscillator (
string  name,
int     slowPeriod
)


Initializes a new instance of the AccumulationDistributionOscillator class using the specified parameters.

### 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.



// In Initialize()
_adosc = new AccumulationDistributionOscillator(name, fastPeriod, slowPeriod);

// In IndicatorUpdateMethod()
{
}

# In Initialize()

# In IndicatorUpdateMethod()
indicator_value = self.adosc.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 a TradeBar. The indicator will only be ready after you prime it with enough data.


private Symbol symbol;

// In Initialize()

// In OnData()
if (data.Bars.ContainsKey(_symbol))
{
}
{
}

# In Initialize()

# In OnData()
if data.Bars.ContainsKey(self.symbol):
indicator_value = self.adosc.Current.Value

### Create Automatic Indicators

The ADOSC method creates an AccumulationDistributionOscillator 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 ADOSC method:

            AccumulationDistributionOscillator QuantConnect.Algorithm.QCAlgorithm.ADOSC (
Symbol                            symbol,
Int32                             fastPeriod,
Int32                             slowPeriod,
*Nullable<Resolution>       resolution,
*Func<IBaseData, TradeBar>  selector
)


Creates a new AccumulationDistributionOscillator 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.

### Get Indicator Values

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

private AccumulationDistributionOscillator _adosc;

// In Initialize()

// In OnData()
{
}
# In Initialize()

# In OnData()


### Visualization

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

private AccumulationDistributionOscillator _adosc;

// In Initialize()

// In OnData()
{
}
# In Initialize()

# In OnData()
