There are limits on how CTAs can advertise their services to the general public. But what about trading education services (classes, etc)? Do the same rules apply? Are there other separate rules governing what can and can't be done?
http://www.nfa.futures.org/NFA-registration/cta/index.HTML The very general answer is, yes there are rules on how a CTA can market themselves and for education, you might not have to register. You should read this carefully.
But specifically, what marketing rules does an education service that is not a CTA (like tradingacademy.com) have to follow?
To my knowledge, none. As long as your are not acting as a CTA. EG, my service costs $XX/ month for....you are OK. If you start promoting returns, getting percentage of profits, etc, I'm not sure.
