# OptimizationTimeFrameParameter (record)

A `TimeFrame` cBot parameter, optimized over a set of time frames 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 OptimizationTimeFrameParameter : OptimizationParameter`1
```

Available since cAlgo.API 5.9.

## Examples

C#:

```csharp
var optimized = new OptimizationTimeFrameParameter("SignalTimeFrame", new[] { TimeFrame.Hour, TimeFrame.Hour4, TimeFrame.Daily });
var fixedValue = new OptimizationTimeFrameParameter("TrendTimeFrame", TimeFrame.Weekly);
Print("{0} candidates: {1}, {2} fixed at {3}", optimized.Name, optimized.Values.Count, fixedValue.Name, fixedValue.Value);
```

Python:

```python
optimized = OptimizationTimeFrameParameter("SignalTimeFrame", [TimeFrame.Hour, TimeFrame.Hour4, TimeFrame.Daily])
fixedValue = OptimizationTimeFrameParameter("TrendTimeFrame", TimeFrame.Weekly)
api.Print(f"{optimized.Name} candidates: {optimized.Values.Count}, {fixedValue.Name} fixed at {fixedValue.Value}")
```

## Constructors

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

## Properties

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