CME Europe, the futures giant’s new London derivatives exchange, has extended an incentive scheme designed to encourage trading in the fledgling bourse's FX contracts, doubling the scheme's bonus pool and the number of firms that can benefit from it.

CME Europe, which launched in April offering trading in FX and biofuels derivatives, announced in May that it would set up a cash incentive scheme to boost trading and build up liquidity in 30 of its FX pairs.
