# Rerouting Directly to a Venue

To compare every historical fill against what a venue would've filled if it had won the swap, use the [`sim run` command](/documentation/flows/replaying-the-market.md#run-a-baseline) with the reroutes set to `venue` and provide a template file. The template defines how the simulator should integrate with the venue and which token pair to include.

```bash
sim run \
  --start-slot 400000000 \
  --end-slot 400010000 \
  --reroute-order-flow venue \
  --venue-templates <FILE>
```

This shows whether the venue would've won on price but not whether a router would've actually routed the swap to it.

It's typically used when the DEX isn't yet integrated with any aggregators yet, but it's also useful for comparing the competitiveness of a venue's prices independent of aggregator routing decisions. In other words, it can be thought of as *"true reality"* instead of *"router's view of reality"*.
