FXOpen provides their partners with the opportunity to make money using PAMM accounts:

In addition to the revenue from your referrals' trades, you can earn by attracting new investors to the risky high-income financial instrument - PAMM accounts. We pay you commission for clients who become Masters or Followers within FXOpen's PAMM technology. The amount of commission depends on your referral's share in the overall balance of a PAMM account. If your client uses our PAMM technology as a Follower, a share of the Master's remuneration will be paid to you as well (depending on the Master's Offer conditions).
