Calyon buys FX margining system from Patsystems

Calyon Financial, the Chicago-based broker, has purchased an FX margining system from Patsystems. The deal comes after the vendor sold its Risk Informer system to Calyon last year to manage its exchange-traded derivatives direct market access business. Risk Informer enables the calculation of margin and management of risk across all asset classes. Calyon says it has taken on the FX margining system from Patsystems because of the successful installation of Risk Informer.
