Banning Some HFT Strategies Helped This Market Grow: Chart

Aquis Exchange Ltd. has doubled its share of public European stock trading since Feb. 8, when it banned what it considers a problematic high-frequency-trading strategy. Aquis says it doesn’t have a beef with HFT firms, it just wants to limit proprietary traders to passively providing price quotes. “We have the same goal as the end investor -- we both want to minimize market impact,” said Doug Cifu, the chief executive of Virtu Financial Inc., an electronic trading company that’s providing more liquidity on Aquis.
