Anyway, I was told that the Patsystems jtrader that the BM Deriv will use is only to be installed at CSA computers. This is a piece of software that traders and brokers have used for over many years, and because it is internet enabled, can be installed on any user pc. Why CSA only? If one trades from home then we need to buy CSA provided computers? Oh, btw CSA supplies pcs at twice the cost of normal pcs, from memory.
