Article 516-15 of the AMF General Regulations sets out the principle by which an investment services provider may only accept an order for execution on a regulated market in derivative financial instruments if it obtains a sufficient margin deposit from the investor.

The AMF has introduced an exception to this principle when the investor is a professional. Article 516-15 of the AMF General Regulations as amended provides that the investment services provider can give the professional investor a specified period of time to constitute the margin.
