Service provider Trading Technologies said market data issues for the London Metal Exchange (LME) reported earlier on Monday appeared to have been resolved, though it was still doing additional checks to ensure stability. Several LME member firms reported prices missing on Monday on LMEtrader, provided directly by Trading Technologies, and Standard TT GUI (graphical user interface) screens, including carry prices, the LME said. Apart from Trading Technologies, there were no reports of issues with any other independent software vendor (ISV) providers, the exchange said.
