Nasdaq Futures, Inc. will require all futures participants using its self-match prevention functionality to select one of two options beginning November: either to have the newest order that might cross with a resting order or quote cancelled (so-called “Cancel Newest”) or to have a resting order or quote cancelled if the newest order might cross with it (so-called “Cancel Oldest”). If a clearing member fails to advise NFX by noon, the following day, which option it prefers, the SMP functionality will default to Cancel Newest.
