ECC Margining

With the introduction of the new margining ECC is now optimising its methods for calculating margin requirements. For instance, new contract specific margin parameters and inter-commodity margin credits have been introduced.

To implement its new margining ECC will be using SPAN®, which is a recognised risk system used by many exchanges and clearing houses.
