Accessing daily data from radarscreen that has 1-minute time compression

["Dean DiCarlo" <junkmayl@xxxxxxxxxxxx>]

I am trying to develop a scan that finds gappers in the morning, but for
some reason the functions opend, closed, and even highd always return -1...
How do i find previous days close and todays open within a radarscreen that
monitors stocks on a 1 minute basis?

The reason behind this scan is I want to be notified when gappers make a new
high or low after 7:00 am.

Thanks...
