Fidessa, the London-based liquidity aggregator, has opened a Sydney office and has 15 people working in Grosvenor Tower on George Street.

Andrew Metcalfe has come from Fidessa Hong Kong to become the company’s operational head. James Hardcastle is head of sales, having transferred from Tokyo, says Steve Grob, Fidessa’s director of group strategy.

Grob says the company is seeking to hire more staff.

Fidessa is on about 26,000 screens globally through a network of about 600 brokers that route order flows from about 160 venues.
