The European derivatives exchange Euronext.Liffe’s new service will help customers slash transaction costs after the company announced it had an option to expand on over-the-counter market.

The trading of equity derivatives on the OTC market means higher profits as its size is much larger than that of the market of exchange-traded products.

Euronext.Liffe purchased CScreen, the provider of a pre-trade price discovery platform for wholesale equity derivatives trading, from Swedish Cinnober Financial Technology, the company said declining to disclose the sum. CScreen is expected to become the basis for for Euronext.Liffe’s new straight-through processing platform. The platform will provide dealers with the possibility to execute all the stages of OTC trade through a single service, Euronext said.

“By offering straight-though processing and a competitive fee structure, the service will make trading easier and help reduce costs and operational risk,” said the company’s chief executive Hugh Freedberg.

The service will be available in Belgium, the Netherlands, Finland, France, Germany, Italy, Portugal, Spain, Switzerland and the UK.
