Chi-X, the biggest alternative stock exchange group, has signalled its plan to push aggressively into the world’s largest trading market by making available for the first time its flagship technology product in the US.

Chi-Tech, the technology business owned by the Nomura-backed Chi-X Global, said today it has started selling its European system MarketPrizm to US and Canadian brokers. Until now the high-speed trading platform has only been available in Europe.
