U.S. option exchanges have rules that distinguish between orders originating from public customers (i.e., not broker-dealers) whose trading behavior is deemed to be “Professional” (i.e., persons or entities trading in a manner more akin to a market maker than to a typical customer) and those whose trading behavior is not. In accordance with these rules, any customer that is not a broker-dealer and averages more than 390 option orders (for its own beneficial account(s)) per day in U.S.-listed options in at least one month of a calendar quarter will be classified as Professional.
Orders submitted on behalf of Professional customers are treated the same as those of broker-dealers for purposes of execution priority and fees.
Brokers are required to conduct a review on at least a quarterly basis to identify those customers who have exceeded the 390 order threshold for any month in that quarter, and such customers will be designated as Professional as of the next calendar quarter.
Order Counting
The definition of an order for these purposes varies slightly across exchanges, and customers seeking specific options counting rules (especially in connection with the use of algorithmic order types that might result in placing orders on both sides of the market under certain circumstances) should review the relevant exchange rulebooks and guidance. However, for purposes of options order counting, an order is generally defined as:
A customer-initiated cancelation and replacement (by any method, including, for example, as a result of Scale orders) of a parent order counts as a new order(s) according to the logic above (e.g., a cancel/replace of a single-leg order counts as one new order, whereas a cancel/replace of a nine-option-leg order counts as nine new orders).
Orders Pegged to the NBBO/BBO
Note that for customers who use options orders pegged to the NBBO or BBO (such as, for example, relative orders or Pegged Volatility orders, or other parent order types designed to move with the NBBO/BBO), each cancel/replace of a child order based on a change in the NBBO/BBO constitutes an additional new order. Customers resting pegged orders in IBUSOPT for participation in RFQ auctions should also be aware that a pegged order will be treated as canceled and replaced each time such order participates in an RFQ auction in IBKR’s system (whether or not such order becomes an initiating order in an on-exchange auction).
Account Aggregation
In calculating order totals, brokers must aggregate the options orders of all beneficially-owned accounts of the customer. IBKR aggregates options orders from an individual’s or entity’s account with those of related joint accounts, trust accounts, and organizational accounts.
Customers will be notified by IBKR upon a status change from a retail customer to a Professional customer. In addition, IBKR’s smart order router is designed to take exchange fees (including differences between professional and non-professional customer fees) into consideration when making routing decisions.
