The glitch comes just weeks after the Qatar Exchange was shut down and all transactions canceled
Dubai Financial Market, the emirate's main bourse, was forced to delay the start of trading on Sunday due to a technical fault, it said in a statement.
Last month, the Qatar Exchange (QE) was also forced to cease trading due to a technical fault.
"The incident occurred during the trading session and consequentially required the stock exchange to cease trading until the incident could be resolved,” a QE spokesperson said.
“Trading then resumed until noon when the QE teams discovered that the technical issue had not been resolved, requiring a further halt to trading. After consultation with QFMA, it was agreed to cancel all transactions that took place today and any orders that had not been executed.”
