How are Non-Professional/Professional Subscriber Defined?


A Non-professional Subscriber is any natural person* whom a market data vendor has determined qualifies as a “Nonprofessional Subscriber” and who is NOT:

(a)registered or qualified with: the Securities and Exchange Commission, the Commodities Futures Trading Commission, any state securities agency, any securities exchange or association, or any commodities or futures contract market or association, nor

(b) engaged as an “investment advisor” as that term is defined in Section 201(11) of the Investment Advisor’s Act of 1940 (whether or not registered or qualified under that Act), nor

(c) employed by a bank or another organization that is exempt from registration under Federal and/or state securities laws to perform functions that would require him or her to be so registered or qualified if he or she were to perform such functions for an organization not so exempt.


Any person or entity who does meet the above criteria (a,b, & c) is considered a Professional Subscriber. For a natural person who works outside of the United States but performs the same functions as someone who would be considered a “Professional” in the United States, that person would be deemd a “Professional”. Please note that an entity such as corporation or group structure is not by definition a “natural person.” A natural person determination is also dependend on whether the trading is conducted in an Individual, Joint or UTMA or IRA account.

Although the different exchanges may have slight variation on the rule they all agree to the basis definition outline above.
