### Examples

C#:

```csharp
var retracement = Chart.DrawFibonacciRetracement("retracement", Bars.OpenTimes.Last(50), Bars.HighPrices.Last(50), Bars.OpenTimes.LastValue, Bars.LowPrices.LastValue, Color.Red);
retracement.Thickness = 2;
Print("Fibonacci lines thickness: {0}", retracement.Thickness);
```

Python:

```python
retracement = api.Chart.DrawFibonacciRetracement("retracement", api.Bars.OpenTimes.Last(50), api.Bars.HighPrices.Last(50), api.Bars.OpenTimes.LastValue, api.Bars.LowPrices.LastValue, Color.Red)
retracement.Thickness = 2
api.Print(f"Fibonacci lines thickness: {retracement.Thickness}")
