# OptimizationTimeSpanParameter (record)

A `TimeSpan` cBot parameter, optimized over a range 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 OptimizationTimeSpanParameter : OptimizationParameter`1
```

Available since cAlgo.API 5.9.

## Examples

C#:

```csharp
var maxHoldTime = new OptimizationTimeSpanParameter("MaxHoldTime", TimeSpan.FromHours(1), TimeSpan.FromHours(8), TimeSpan.FromHours(1));
var cooldown = new OptimizationTimeSpanParameter("Cooldown", TimeSpan.FromMinutes(30));
Print("{0}: {1} to {2} by {3}, {4} fixed at {5}", maxHoldTime.Name, maxHoldTime.Min, maxHoldTime.Max, maxHoldTime.Step, cooldown.Name, cooldown.Value);
```

Python:

```python
from System import TimeSpan
maxHoldTime = OptimizationTimeSpanParameter("MaxHoldTime", TimeSpan.FromHours(1), TimeSpan.FromHours(8), TimeSpan.FromHours(1))
cooldown = OptimizationTimeSpanParameter("Cooldown", TimeSpan.FromMinutes(30))
api.Print(f"{maxHoldTime.Name}: {maxHoldTime.Min} to {maxHoldTime.Max} by {maxHoldTime.Step}, {cooldown.Name} fixed at {cooldown.Value}")
```

## Constructors

- `public OptimizationTimeSpanParameter(string name, TimeSpan min, TimeSpan max, TimeSpan step)` — Optimizes the parameter over the range the minimum to the maximum by the step. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationTimeSpanParameter/Constructor/index.md)
- `public OptimizationTimeSpanParameter(string name, TimeSpan value)` — Holds the parameter fixed at the given value. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationTimeSpanParameter/Constructor/index.md)
- `public OptimizationTimeSpanParameter(OptimizationTimeSpanParameter original)` —  [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationTimeSpanParameter/Constructor/index.md)

## Properties

- `public TimeSpan Max {get;}` — Gets the inclusive maximum of the range. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationTimeSpanParameter/Max/index.md)
- `public TimeSpan Min {get;}` — Gets the inclusive minimum of the range. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationTimeSpanParameter/Min/index.md)
- `public TimeSpan Step {get;}` — Gets the step of the range. [details](https://help.ctrader.com/ctrader-algo/references/Plugin/Optimization/OptimizationTimeSpanParameter/Step/index.md)
