Revenues in the European division of Australian high-frequency trading group Tibra Trading jumped by almost a half last year, a period during which such firms benefited from volatility sparked by the eurozone crisis.

Tibra Trading Europe Ltd, one of the largest high-frequency trading firms in Europe, reported a 45% increase in revenues to €26.7m for the year ended June 30, 2012, according to accounts filed with Companies House this month. Pre-tax profits rose 631% to €7m, the filings showed.
