Nonprofessional user service
All users are considered âprofessionalâ until the vendor properly qualifies him/her as a nonprofessional.
A nonprofessional user is an individual who uses NYSE data for personal, non-business use. Authorization requests do not need to be submitted to NYSE before permissioning the individual, however, the vendor must qualify each individual to confirm their intended use of the data.
In addition, a nonprofessional must not be:
--Registered or qualified with the SEC (Securities Exchange Commission), the Commodity Futures Trading Commission, any state securities agency, any securities exchange or association, or any commodities or futures contract market or association.
--Engaged as an investment advisor.
--Employed by a bank or other 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.
It is the responsibility of the vendor to qualify each nonprofessional user according to all of the above points. For each nonprofessional user, an Exhibit B â Non Professional Usage Addendum must be completed and retained by the vendor. NYSE does not require a copy, but reserves the right to request it along with additional details related to their nonprofessional status.
