Introducing
May 8, 2020
Many major exchanges, trading venues, regulatory bodies, and other data providers require data vendors like Massive to collect and maintain specific personal and employment information from subscribers accessing certain market data. This is necessary to determine whether a user qualifies as a Professional Subscriber or a Non-Professional Subscriber.
Accurate classification is essential. Providing complete and truthful information helps ensure uninterrupted access to Massive’s services and avoids potential penalties, fines, or access restrictions that may result from misclassification under exchange and vendor rules.
At Massive, these classifications directly impact which plans you are eligible for. Our plans labeled for "Individual Use" and "Non-Pro Use" are exclusively for Non-Professional Subscribers. Conversely, Professional Subscribers are required to utilize our designated Business plans, which are structured to meet the more extensive licensing and usage requirements associated with professional data consumption.
If you are unsure of your classification, please review the information below or contact our support team for guidance.
Who is a Non-Professional Subscriber?
A Non-Professional Subscriber is any natural person who receives stock market data solely for their personal, non-business use and who is not otherwise a Professional Subscriber.
This means that a corporation, limited liability company, trust, joint venture, limited or general partnership, unincorporated organization, or other entity cannot be a Non-Professional Subscriber.
Who is a Professional Subscriber?
A Professional Subscriber is any individual working in the United States who is:
Additionally, a person who works outside of the United States is a Securities Professional if they perform the same function(s) as a person who would be considered a Professional Subscriber in the United States.
During the registration process, we ask you to answer 11 questions to determine your subscriber status. If you answer "No" to the first question or if you answer “Yes” to any of the subsequent questions (questions 2-11) you will remain qualified as a Professional Subscriber.
If you receive market data for your personal, non-business use through your organization's account or using your organization's information, you would qualify as a Professional Subscriber. Your account must be in your own name to qualify as a Non-Professional Subscriber.
Yes, retired, non-working, or inactive Professional Subscribers no longer providing services as a Professional Subscriber may qualify as a Non-Professional Subscriber if they are listed as Not-Registered with FINRA. Please keep in mind that you must contact us if your status changes, and you must re-verify your status as well.
Yes, but only if you can answer "Yes" to the first question and "No" to the other ten questions.
Yes, if you, as the trustee or beneficiary, are unpaid natural persons that otherwise qualify as Non-Professional Subscribers.
No, the Investment Club is an organization; therefore, the Investment Club is not a natural person and cannot be a Non-Professional Subscriber.
Individual members of an Investment Club may still qualify as Non-Professional Subscribers individually if they are an unpaid natural person associated with the Investment Club, who otherwise qualifies as a Non-Professional Subscriber as well.
Yes, absolutely! You will need to contact us so that we can help you determine which one of our many Enterprise APIs is right for your use case.
If you have any questions or would like to learn more about any of our products, please don’t hesitate to contact us.
