Brokers Report Login, Trading and Withdrawal Disruptions
Other brokers have also faced technical disruptions affecting clients' access to trading services and positions. Interactive Brokers experienced login problems linked to a technical issue at certain Asia-Pacific data centres. The broker said access was restored within an hour.
At XTB, a platform failure prevented some clients from modifying or closing CFD positions. The broker said the disruption affected around 0.4% of its 25 million positions and attributed it to a technical limitation in data transfers between its trading engine and its web and mobile platforms.
Separately, OANDA Japan temporarily delayed withdrawals as a precaution following a cyberattack on a third-party hosting provider used by FX traders. The provider, GMO Internet Group, said unauthorised programs had been installed in customer server environments, potentially exposing stored MetaTrader login credentials.
