TradElect was the London Stock Exchange's main electronic trading platform from 2007 to 2011. It ran on Microsoft Windows, using .NET technology and Microsoft SQL Server. Its development took 4 years from project inception to rollout and had a total cost of £40m. The impetus for the development of TradElect was the rise of algorithmic trading and the liberalisation of the trading sector in Europe due to the Markets in Financial Instruments Directive. Both of these factors meant that stock exchanges - previously facing little or no competition〔 - had to offer faster response times to be competitive. The system which TradElect replaced, Sets, was 10 years old and took 140ms to complete a trade, compared to TradElect's 10ms. In April 2010 the Oslo Stock Exchange also adopted TradElect, as part of a strategic partnership agreement. The Johannesburg Stock Exchange also adopted TradElect. ==Downtime== On 8 September 2008, TradElect trading was mostly unavailable for over 7 hours, on what the Wall Street Journal described as a "huge trading day". Traders walked out of the London Stock Exchange in protest. Another major technical fault had occurred less than a year earlier.〔 The London Stock Exchange claimed that the TradElect software was not to blame, instead blaming an unspecified fault with "network software". However, Celent analyst Cubillas Ding noted that this outage, and three previous ones, all coincided with large spikes in trading volumes, from different economic events, and concluded that the LSE's technology could not cope with the high trading volumes.〔 Microsoft had previously used TradElect as a case study in marketing material to position its Windows operating system as suitable for "highly reliable" systems. It did not respond to requests for comment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TradElect」の詳細全文を読む スポンサード リンク
