AOT, the Dutch independent securities and derivatives trading firm, has pulled out of market making on Euronext Amsterdam due to the poor performance of the exchange's electronic trading platform.

AOT said in a statement: "Following discussions with Euronext it has become apparent that the exchange cannot provide any technical guarantees regarding the performance of the trading system. AOT will conduct an enquiry to assess whether incurred damages resulting from the malfunctioning of the electronic platform can be claimed."
