Need help exit positions next day

I have a strategy that needs to buy positions today and sell the next day. I just have a problem setting up the exit condition the next day. How can this be implemented?

You have to place a NRML order in Position Builder. Use the Universal Exit for the exit condition.

On the first day use a time which is beyond trading hours. For eg Time > 1600. On next day change the time to exit during market hours.
