What is Throttle Control Mechanism?
According to the figures provided by the SEHK, the new AMS/3 system will allow a peak order input rate of 12,000 orders per minute for a total capacity of 1,200,000 trades per 4 hour trading day. However, the throttle control mechanism as imposed by the SEHK restricted this capacity down to 60 order input per minutes on each OG, so as to ensure the integrity and stability of the AMS/3 under stressed conditions.
