TradElect runs on HP ProLiant servers running, in turn, Windows Server 2003. Since then, the CEO that brought TradElect to the LSE, Clara Furse, has left without saying why she was leaving. Sources in the City-London's equivalent of New York City's Wall Street--say that TradElect's failure was the final straw for her tenure. The new CEO, Xavier Rolet, is reported to have immediately decided to put an end to TradElect. LSE's competition, such as its main rival Chi-X with its MarketPrizm Linux based trading platform software, was able to deliver a high level of performance and in general it was running rings around TradElect."
