Today's fast-paced and ultra-competitive marketplace requires the use of sophisticated and cutting-edge technology. It is no longer sufficient to simply provide traders with executions of their stock orders. An order execution system must provide real-time market data, almost instantaneous executions and financial account monitoring, so that traders can perform at the highest level. Moreover, a system must be flexible so that traders can quickly and easily personalize preferences and formats - from 'look and feel' to execution venue destinations to sophisticated order routing algorithms.
