If an advisory service of any kind were promoting itself as a trade-along operation for others to follow with intent to profit, then that falls under the CTA ruling umbrella. Most signal advisory attempts try to fit within the educational = entertainment exemption with mandated CFTC disclaimers in place. imo a signal service = trade-along advisory is realistically impossible to succeed with. No individuals can or will blindly follow someone else' trade signals and execute profitably over time. It has never been done and will never be done purely from a human nature aspect. But for those who seriously attempt to make that work, they are advising others on specific trade recommendations, which in turn mandates CTA status and full compliance.
