Credit Suisse said that its CrossFinder automated trading system chalked up record volume of turnover, with 210.1 million shares processed on 16 July.

The volume has been growing by an average of 30 per cent a month throughout 2008, the Swiss bank said, which it claims has allowed CrossFinder to eclipse many of the traditional agency share-crossing systems on Wall Street.

Credit Suisse has made a major investment in CrossFinder technology over the past year, and clients have taken notice," said Jose Marques, managing director and head of CrossFinder. "We will continue to invest in CrossFinder and provide the enhanced speed, capacity and reliability they have come to recognise us for," he added.
