Quote from JTMAN:
And also about FINRA not being an SRO, which you went back and deleted after I pointed that out as well. So basically all points you made were incorrect.
Question I am trying to answer is why would some props be members of an exchange and FINRA while others are only members of an exchange?
I am still doing some research, thus retracting what I have said until I complete my research, here is what I have found so far from FINRA website...
Who regulates them: With few exceptions, broker-dealers must register with the Securities and Exchange Commission (SEC) and be members of FINRA. Individual registered representatives must register with FINRA, pass a qualifying examination, and be licensed by your state securities regulator before they can do business with you. You can obtain background information on broker-dealers and registered representativesâincluding registration, licensing, and disciplinary historyâby using FINRA BrokerCheck or calling us toll-free (800) 289-9999. You can also contact your state securities regulator. To find your regulator, check the government listing of your phone book or contact the North American Securities Administrators Association at www.nasaa.org or (202) 737-0900.
