Traiana, the post-trade unit of interdealer broker Icap, has signed up 11 of the world's largest prime brokers to a platform processing contract-for-difference trades, which have increased in volume on the back of activity from high-frequency trading firms.

A number of the world's largest prime brokers - including Credit Suisse, UBS and Morgan Stanley - have agreed to route post-trade flow for their clients' CFD equity swaps businesses to the platform. The platform handles trade give-ups, allocations, and swap confirmation processes, as well as clearing for interbank trades.
