# OptimizationBooleanParameter (record)

A `bool` cBot parameter, optimized over a set of values or held fixed.

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.

## Definition

```csharp
public class OptimizationBooleanParameter : OptimizationParameter`1
```

Available since cAlgo.API 5.9.

## Examples

C#:

```csharp
var optimized = new OptimizationBooleanParameter("UseTrailingStop", new[] { true, false });
var fixedValue = new OptimizationBooleanParameter("UseStopLoss", true);
Print("{0} optimized: {1}, {2} fixed at {3}", optimized.Name, optimized.IsOptimized, fixedValue.Name, fixedValue.Value);
```

Python:

```python
optimized = OptimizationBooleanParameter("UseTrailingStop", [True, False])
fixedValue = OptimizationBooleanParameter("UseStopLoss", True)
api.Print(f"{optimized.Name} optimized: {optimized.IsOptimized}, {fixedValue.Name} fixed at {fixedValue.Value}")
```

## Constructors

- `public OptimizationBooleanParameter(string name, IEnumerable<bool> values)` — Optimizes the parameter over the given values. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationBooleanParameter/Constructor/index.md)
- `public OptimizationBooleanParameter(string name, bool value)` — Holds the parameter fixed at the given value. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationBooleanParameter/Constructor/index.md)
- `public OptimizationBooleanParameter(OptimizationBooleanParameter original)` —  [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationBooleanParameter/Constructor/index.md)

## Properties

- `public IReadOnlyList<bool> Values {get;}` — Gets the discrete set of values to optimize over. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationBooleanParameter/Values/index.md)
