Three windows
Pre-market trading runs before 09:30 ET, the regular session runs from 09:30 to 16:00 ET, and after-hours trading follows the close.
Volume is thinner outside the regular session, so prices can jump on small orders.
Which one counts
TraderChamp contests use the regular session only. Moves before the open or after the close do not change your score.
