The close gate held every Vest entry within four holds of any close,
which with a 2 h hold meant no weekday entry from about 9 AM to 5 PM ET
for the one-hour maintenance break. That hour reopens before the reset,
as CME's daily break does for futures legs, so only a weekend or holiday
closure gates an entry now.
