New York - March 23, 2010 – Portware, the leading provider of global, multi-asset electronic trading systems, today announced that it has partnered with Thomas Weisel Partners to integrate their suite of algorithmic strategies into Portware Enterprise using the FIX Algorithmic Trading Definition Language (FIXatdl).
