Avery ChenHong Kong Exchanges and Clearing (0388) says the trading suspension of the derivatives market last September was due to an isolated software issue in the vendor-supplied system. That was the first time the bourse operator had halted derivatives trading. On September 5, 2019, most futures and options exchange players found their systems were not operating normally, as connections to the Hong Kong Futures Automatic Trading System were interrupted. The disconnections were caused by an erroneous logic in a vendor-supplied matching engine partition, said the HKEx incident report. After testing and verification of the interim solution recommended by the software vendor, trading resumed on September 6.
