# How does Rollover on expiry work ?

### Rollover on expiry

This Parameter takes three inputs

* Choose expiry

* Hour

* Minutes

![Rollover after expiry](https://storage.crisp.chat/users/helpdesk/website/948b8c26d046a000/image_sxcycj.png)

As intuitive the name is, this parameter rolls over your derivative instruments on the day of expiry at the Hour and Minute specified by you.

If today is expiry day of any underlying symbol in the strategy, all open futures or options positions of that underlying will be rolled over to next week/month expiry as per selected settings.

|| Note: If you have multiple derivative positions and you want to roll over only one type and square off the other. You will have to handle the square off in your condition builder.
