Environments: Desktop supported · CLI supported · Cloud supported.

C#:

```csharp
RainbowOscillator RainbowOscillator(DataSeries source, int levels, MovingAverageType maType)
```

Python:

```python
api.Indicators.RainbowOscillator(source: DataSeries, levels: int, maType: MovingAverageType) -> RainbowOscillator
```

### Parameters

- `source` (`DataSeries`, Python `DataSeries`): The price source data used for calculation.
- `levels` (`int`, Python `int`): The value of the levels used for calculation.
- `maType` (`MovingAverageType`, Python `MovingAverageType`): The Moving Average type used for calculation.

### Returns

### Examples

C#:

```csharp
var rainbow = Indicators.RainbowOscillator(Bars.ClosePrices, 9, MovingAverageType.Simple);
Print("Rainbow Oscillator: {0}", rainbow.Result.LastValue);
```

Python:

```python
rainbow = api.Indicators.RainbowOscillator(api.Bars.ClosePrices, 9, MovingAverageType.Simple)
api.Print(f"Rainbow Oscillator: {rainbow.Result.LastValue}")
```
