# OptimizationBooleanParameter constructor

Member of [OptimizationBooleanParameter](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationBooleanParameter/index.md).

## OptimizationBooleanParameter(string name, IEnumerable<bool> values)

Optimizes the parameter over the given values.

Environments: Desktop supported · CLI not supported · Cloud not supported.

- CLI: Available to plugins only, and plugins cannot run in the CLI.
- Cloud: Available to plugins only, and plugins cannot run in the cloud.

C#:

```csharp
public OptimizationBooleanParameter(string name, IEnumerable<bool> values)
```

Python:

```python
OptimizationBooleanParameter(name: str, values: Iterable[bool])
```

### Parameters

- `name` (`string`, Python `str`): The cBot parameter name.
- `values` (`IEnumerable<bool>`, Python `Iterable[bool]`): The discrete set of values to optimize over.

Available since cAlgo.API 5.9.

### Examples

C#:

```csharp
var parameter = new OptimizationBooleanParameter("UseTrailingStop", new[] { true, false });
Print("{0} is optimized over {1} values", parameter.Name, parameter.Values.Count);
```

Python:

```python
parameter = OptimizationBooleanParameter("UseTrailingStop", [True, False])
api.Print(f"{parameter.Name} is optimized over {parameter.Values.Count} values")
```

## OptimizationBooleanParameter(string name, bool value)

Holds the parameter fixed at the given value.

Environments: Desktop supported · CLI not supported · Cloud not supported.

- CLI: Available to plugins only, and plugins cannot run in the CLI.
- Cloud: Available to plugins only, and plugins cannot run in the cloud.

C#:

```csharp
public OptimizationBooleanParameter(string name, bool value)
```

Python:

```python
OptimizationBooleanParameter(name: str, value: bool)
```

### Parameters

- `name` (`string`, Python `str`): The cBot parameter name.
- `value` (`bool`, Python `bool`): The fixed value.

Available since cAlgo.API 5.9.

### Examples

C#:

```csharp
var parameter = new OptimizationBooleanParameter("UseStopLoss", true);
Print("{0} is fixed at {1}", parameter.Name, parameter.Value);
```

Python:

```python
parameter = OptimizationBooleanParameter("UseStopLoss", True)
api.Print(f"{parameter.Name} is fixed at {parameter.Value}")
```

## OptimizationBooleanParameter(OptimizationBooleanParameter original)



Environments: Desktop supported · CLI not supported · Cloud not supported.
