An after-hours move that carries into the next session becomes an opening gap, and LH's gap history is the best guide to what happens next: 0% of LH gap-ups have fully filled, and 100% of gap-downs have filled over the past 5 years. Fill rates this high mean a large after-hours move is more often faded than extended.
