Trading on the London Stock Exchange resumed on Thursday afternoon after a technology glitch halted transactions across the market for 3.5 hours. The outage was the worst since the almost day-long closure of the LSE in September 2008, and comes after similar outages at rival European exchanges in recent months. It was not clear how much trading had migrated to rival platforms such as Chi-X Europe and BATS Europe, a US-based operator that seized on the LSE’s woes to advertise on Thursday that its platform remained open for business.
