Pragma Financial Systems and Weeden & Co. are shining many lights into the fragmented marketplace with a new product they call “a liquidity management tool.” The two have partnered to develop a new “dynamic” aggregation product, called OnePipe, to help institutional investors find liquidity faster in non-displayed markets. OnePipe distributes an order among 25-and soon, more than 30-liquidity sources from a central position on the user’s order management system. Those sources include “passive stream liquidity sources, dark pools and other internalization pools,” said Doug Rivelli, managing director at Weeden.
