Use negative numbers to find stocks trading above the pre-market high of the day. For example, set the max to -0.05 to find stocks which are trading at least 5 cents above the pre-market high of the day.

These filters are available before the market is open, while the market is open and during the post market session.

The below high filters use 0 for the high of the day. The position in range filters use 100.
