Monthly Review for Professional Orders
If you (a Priority Customer) average more than 390 orders per day during any calendar month, your orders must be represented as Professional orders for the next calendar month. Members must change the representation within five days after the end of each calendar month instead of after each calendar quarter; the Exchange proposes implementing this on July 1, 2026.
