Replying to [Rahmat1961]:
You don't want to sign a MFPA.
The MFPA as previously stated is worthless. Asking for it is a signal to a principal that they are dealing with someone who is not well versed.
You need to attach yourself to a group or principal whom you trust and who trust you. By conveying specific value to them as an agent meaning that you need to bring to the table more than just a connection to a possible buyer/seller etc., but good skills. If you have this and you want to be attached to a group as a formal agent then what you want is an agency agreement. There are model agency agreements including ICC models, the rules of agency are well articulated in international Trade law and agents have protection in the legal codes of many countries but your role has to be strictly defined, your territory defined, commission rates defined.
The way you avoid circumvention is by finding an honorable principal, and conveying real value to that principal so that he sees that you are too valuable to circumvent. To convey value you must know as much if not more about many aspects of trading than your principal.
The moment you sign an NCND or MFPA you are signing worthless agreements that simply signal "here is someone to manipulate, use, circumvent, and discard." you must find an honorable principal to represent first and bring enough knowledge to the table that they consider retaining you.
