Environments: Desktop supported · CLI supported · Cloud supported.

## Definition

```csharp
public enum RunningMode
```

## Examples

C#:

```csharp
using cAlgo.API;

namespace cAlgo.Robots
{
    // This sample shows how to use the RunningMode property of your robot
    public partial class RunningModeSample : Robot
    {
        protected override void OnStart()
        {
            switch (RunningMode)
            {
                case RunningMode.RealTime:
                    Print("Trading on live market data");
                    break;

                case RunningMode.SilentBacktesting:
                    Print("Backtesting with the visual mode off");
                    break;

                case RunningMode.VisualBacktesting:
                    Print("Backtesting with the visual mode on");
                    break;

                case RunningMode.Optimization:
                    Print("Running in the optimizer");
                    break;
            }
        }
    }
}
```

Python:

```python
class RunningModeSample():
    def on_start(self):
        if api.RunningMode == RunningMode.RealTime:
            api.Print("Trading on live market data")
        elif api.RunningMode == RunningMode.SilentBacktesting:
            api.Print("Backtesting with the visual mode off")
        elif api.RunningMode == RunningMode.VisualBacktesting:
            api.Print("Backtesting with the visual mode on")
        elif api.RunningMode == RunningMode.Optimization:
            api.Print("Running in the optimizer")
```
