# FibonacciLevel (interface)

Represents the Fibonacci Level.

Environments: Desktop supported · CLI supported · Cloud supported.

## Definition

```csharp
public interface FibonacciLevel
```

## Examples

C#:

```csharp
using cAlgo.API;

namespace cAlgo
{
    // This sample shows how to use a chart Fibonacci Retracement levels property to modify the fibonacci levels
    public partial class FibonacciLevelSample : Indicator
    {
        protected override void Initialize()
        {
            var period = Chart.LastVisibleBarIndex - Chart.FirstVisibleBarIndex;

            var max = Bars.HighPrices.Maximum(period);
            var min = Bars.LowPrices.Minimum(period);

            var fibonacciRetracement = Chart.DrawFibonacciRetracement("FibonacciRetracement", Chart.FirstVisibleBarIndex, max, Chart.LastVisibleBarIndex, min, Color.Red);

            foreach (var level in fibonacciRetracement.FibonacciLevels)
            {
                Print(level.Percent);

                if (level.Percent > 62) level.IsVisible = false;
            }
        }

        public override void Calculate(int index)
        {
        }
    }
}
```

Python:

```python
import clr
clr.AddReference("cAlgo.API")

from cAlgo.API import *

class Test():
    def initialize(self):
        period = api.Chart.LastVisibleBarIndex - api.Chart.FirstVisibleBarIndex

        maxValue = Functions.Maximum(api.Bars.HighPrices, period)
        minValue = Functions.Minimum(api.Bars.LowPrices, period)

        fibonacciRetracement = api.Chart.DrawFibonacciRetracement("FibonacciRetracement", api.Chart.FirstVisibleBarIndex, maxValue, api.Chart.LastVisibleBarIndex, minValue, Color.Red)

        for level in fibonacciRetracement.FibonacciLevels:
            print(level.Percent)
            if level.Percent > 62:
                level.IsVisible = False
```

## Properties

- `bool IsVisible {get; set;}` — Defines if the level is visible. [details](https://help.ctrader.com/ctrader-algo/references/Chart/Drawings/Fibonacci/FibonacciLevel/IsVisible/index.md)
- `double Percent {get; set;}` — Gets or sets the level percent. [details](https://help.ctrader.com/ctrader-algo/references/Chart/Drawings/Fibonacci/FibonacciLevel/Percent/index.md)
- `double? Price {get; set;}` — Gets or sets the level price. [details](https://help.ctrader.com/ctrader-algo/references/Chart/Drawings/Fibonacci/FibonacciLevel/Price/index.md)
- `DateTime? Time {get; set;}` — Gets or sets the level time. [details](https://help.ctrader.com/ctrader-algo/references/Chart/Drawings/Fibonacci/FibonacciLevel/Time/index.md)

## Deprecated members

- `double PercentLevel {get; set;}` — Use Percent instead
