ESMA (the European Securities and Market Authority) sets limits to the amount of leverage that a retail client may be exposed to on various CFD products. Professional clients are not affected by these rules and are therefore not provided by this protection. Professional clients may lose the right of access to the OAFS (the Office of the Arbiter for Financial Services), which is available to retail clients unless they are an individual (professional client) trading in a personal ('consumer') capacity and not by way of business. Fund segregation, as well as the investor compensation scheme, remain unchanged for both retail and professional customers.
