# OptimizationProcess.Passes

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

Gets the passes completed so far, ordered by pass id. While running this grows as passes finish; on completion it holds every pass.

C#:

```csharp
IReadOnlyList<OptimizationPass> Passes {get;}
```

Python:

```python
optimizationProcess.Passes: Sequence[OptimizationPass]
```

### Returns

`IReadOnlyList<OptimizationPass>` — 

Available since cAlgo.API 5.9.

### Examples

C#:

```csharp
Optimization.Completed += args =>
{
    var profitablePasses = args.Process.Passes.Count(pass => pass.NetProfit > 0);
    Print("{0} of {1} passes were profitable", profitablePasses, args.Process.Passes.Count);
};
```

Python:

```python
def on_start(self):
    api.Optimization.Completed += self.on_optimization_completed

def on_optimization_completed(self, args):
    profitablePasses = len([p for p in args.Process.Passes if p.NetProfit > 0])
    api.Print(f"{profitablePasses} of {args.Process.Passes.Count} passes were profitable")
```
