# Custom delay (delay\_ms)

Every transaction is temporarily held during this window to search for profitable arbitrage opportunities:

* If no arbitrage is found, the transaction is released to the leader as a single standalone transaction.
* If an opportunity is found, the transaction is included in an atomic bundle together with the arbitrage leg.

For specific use cases, some users may prefer different behavior:

* **Higher delay (e.g. 100 ms)** — maximizes the probability of discovering and landing arbitrage atomically.
* **Lower delay (e.g. 0 ms)** — minimizes latency but significantly decreases the chances of landing arbitrage atomically.

Kolibrio supports this via a custom query parameter.

```
delay_ms=50
```

#### Example

```

&rev_recv=REVENUE_SHARE_ADDRESS
&tx_broadcast_mode=public
&delay_ms=75
```
