Resolution requires that a ball has been played in the professional tennis match. If the match does not occur before play begins due to player injury, walkover, forfeiture, or other cancellation, the market resolves to a fair price. If the match is postponed or delayed, the market remains open and closes after the rescheduled match concludes within two weeks.
