# no_combos_produced

The settings produce no combinations to test, so nothing ran.

## What happened

A run that would test zero combinations is an error, not an empty success. The usual reasons are a symbol that has no data yet, a setting that cannot be resolved, or nothing selected. The run ends before it spends any compute.

## What to do

Open the run's detail for the reasons it lists, fix the selection, and start the run again.

## Example

```json
{
  "status": "failed",
  "error": {
    "code": "no_combos_produced",
    "message": "These settings produce no combinations to test.",
    "detail": {
      "reason": "this selection produces zero combinations"
    }
  }
}
```
