# IIndicatorsAccessor.VolumeOscillator

Member of [IIndicatorsAccessor](https://help.ctrader.com/ctrader-algo/references/Indicators/IIndicatorsAccessor/index.md).

## VolumeOscillator(int shortTerm, int longTerm)

The Volume Oscillator indicator is the difference between two moving averages.

Environments: Desktop supported · CLI supported · Cloud supported.

C#:

```csharp
VolumeOscillator VolumeOscillator(int shortTerm, int longTerm)
```

Python:

```python
api.Indicators.VolumeOscillator(shortTerm: int, longTerm: int) -> VolumeOscillator
```

### Parameters

- `shortTerm` (`int`, Python `int`): The fast moving average period
- `longTerm` (`int`, Python `int`): The slow moving average period

### Returns

`VolumeOscillator` — Volume Oscillator indicator instance

### Examples

C#:

```csharp
var volumeOscillator = Indicators.VolumeOscillator(9, 21);
Print("Volume Oscillator: {0}", volumeOscillator.Result.LastValue);
```

Python:

```python
volumeOscillator = api.Indicators.VolumeOscillator(9, 21)
api.Print(f"Volume Oscillator: {volumeOscillator.Result.LastValue}")
```

The Volume Oscillator indicator is the difference between two moving averages.

Environments: Desktop supported · CLI supported · Cloud supported.

C#:

```csharp
VolumeOscillator VolumeOscillator(Bars bars, int shortTerm, int longTerm)
```

Python:

```python
api.Indicators.VolumeOscillator(bars: Bars, shortTerm: int, longTerm: int) -> VolumeOscillator
```

### Parameters

- `bars` (`Bars`, Python `Bars`): The Bars that will be used by indicator, you can pass another timeframe/symbol bars
- `shortTerm` (`int`, Python `int`): The fast moving average period
- `longTerm` (`int`, Python `int`): The slow moving average period

### Returns

`VolumeOscillator` — Volume Oscillator indicator instance

### Examples

C#:

```csharp
var dailyBars = MarketData.GetBars(TimeFrame.Daily);
var dailyVolumeOscillator = Indicators.VolumeOscillator(dailyBars, 9, 21);
Print("Daily Volume Oscillator: {0}", dailyVolumeOscillator.Result.LastValue);
```

Python:

```python
dailyBars = api.MarketData.GetBars(TimeFrame.Daily)
dailyVolumeOscillator = api.Indicators.VolumeOscillator(dailyBars, 9, 21)
api.Print(f"Daily Volume Oscillator: {dailyVolumeOscillator.Result.LastValue}")
```
