MFG throttling algorithm is based on x orders in y seconds. For example, if ThrottlePeriod = 5 and ThrottleOrderRate = 15, it is possible for a FIX client to send all 15 orders in the first second after which the MFG throttle ensures no further orders are processed until the remaining 4 seconds have elapsed. Orders are throttled using a sliding window.

All messages exceeding the users predetermined throttle rate are queued in monitor until next rolling window if session config parameter "RejectOrderOnReachingThrottleLimit" is set false.

The maximum number of orders and time period used for throttling will be configured by Matching service. This cannot be overridden until further notice from Matching Reuters.
