Citigroup has completed an overhaul of its US electronic trading platform for equities, which has resulted in closer links between its electronic and sales trading desks that have historically been kept separate, the bank has said.

The revamp forms part of the US bank's push to help clients locate buyers and sellers for their equity orders amid a continued environment of low trading volumes, and sees Citi follow a number of its peers in bringing once separate trading desks closer together.
