Can I refer clients to CopyFX Traders if I am already a RoboForex Partner?

Yes, you can. To participate in the program, simply select a Trader from the Rating, generate a partner link in their profile, and promote the Trader's services among potential Investors.
If you want to include the attracted Investor in your partner network, simply add your AgentID (partner code) to the generated link. 

You can do this on the "Links" page of your Members Area.
