| EndAnchor                                                                   | An **IDrawingTool's ChartAnchor** representing the end point of the drawing object                |
| ExtensionAnchor                                                             | An **IDrawingTool's ChartAnchor** representing the extension point of the drawing object          |
| [PriceLevels](/developer/desktop-sdk/references/common/drawing/pricelevels) | A collection of prices calculated by the drawing object                                           |
| TextLocation                                                                | An enum determining the text location; can be set to **TextLocation.Off** to remove text          |

## Examples

```csharp
// Instantiates a Fibonacci Extension
FibonacciExtensions myFibExt = Draw.FibonacciExtensions(this, "tag1", true, 4, Low[4], 3, High[3], 1, Low[1]);

// Extend the Fibonacci Extension object's lines to the right
myFibExt.IsExtendedLinesRight = true;
```
