# ChartElliottWaveBase (interface)

Represents the shared options of the Elliott Wave chart objects. An Elliott Wave is an ordered list of labelled pivots joined by a polyline; the wave degree drives the label notation.

Environments: Desktop supported · CLI works differently · Cloud works differently.

- CLI: Created and kept with all its properties, but never drawn: the CLI displays no chart.
- Cloud: Created and kept with all its properties, but never drawn: the cloud displays no chart.

## Definition

```csharp
public interface ChartElliottWaveBase
```

Available since cAlgo.API 5.10.

## Examples

C#:

```csharp
foreach (var wave in Chart.FindAllObjects<ChartElliottWaveBase>())
{
    wave.Degree = ChartElliottWaveDegree.Intermediate;
    wave.ShowLabels = true;
    Print("Elliott wave: {0} | Type: {1} | Degree: {2}", wave.Name, wave.ObjectType, wave.Degree);
}
```

Python:

```python
wave = api.Chart.DrawElliottCorrection("correction", ChartPoint(api.Bars.OpenTimes.Last(40), api.Bars.HighPrices.Last(40)), ChartPoint(api.Bars.OpenTimes.Last(30), api.Bars.LowPrices.Last(30)), ChartPoint(api.Bars.OpenTimes.Last(20), api.Bars.HighPrices.Last(20)), ChartPoint(api.Bars.OpenTimes.Last(10), api.Bars.LowPrices.Last(10)), Color.Blue)
wave.Degree = ChartElliottWaveDegree.Intermediate
wave.ShowLabels = True
api.Print(f"Elliott wave: {wave.Name} | Type: {wave.ObjectType} | Degree: {wave.Degree}")
```
