The project, which has cost tens of millions of pounds, has involved Euronext Liffe moving the Paris, Brussels and Amsterdam exchanges onto Liffe's proprietary trading platform, Connect, following the acquisition of Liffe by Euronext three years ago.
The Paris and Brussels exchanges moved to the Liffe Connect platform last year, and the Amsterdam exchange is due to move to Connect in September.
To prepare for the extra demand on its trading system, Euronext Liffe has developed a new version of Connect to coincide with the migration of the Amsterdam exchange.
Euronext Liffe has also increased the capacity of its Sun F15K servers to handle an increased number of transactions coming in from traders.
Clearing house Euroclear has signed up Accenture to help it design a single system for settling European domestic and cross-border trades. Earlier this year Euroclear delayed the planned go-live date for the single settlement engine until 2006 to allow for harmonisation in European business processes.
