AFET has recognized that the good governance is the key success factor since it enhances the reliability, accuracy, fairness and transparency of the exchange. To ensure the exchange's integrity, market surveillance function was established to monitor the trading activities all through the trading hours to avoid the violation, such as price distortion and price manipulation, which may cause any lost or damage to the invertors or other stakeholders. Moreover, we also oversee the member's activities to ensure that they are all complied with related rules and regulations. The electronic exchange trading system is one of the key area in our concern so that we keep closed monitoring to ensure efficiency and reliability of the system and that it meets the general acceptable standards.
