Enforce Rate Limit via Pause (Equities Only)

When Enforce Rate Limit via Pause is set to False, the existing Port Order Rate Threshold, Sustained Port Order Rate Threshold, Symbol Order Rate Threshold, and Sustained Symbol Order Rate Threshold port attributes will be enforced by rejects (as described). When Enforce Rate Limit via Pause is set to True, Port Order Rate Threshold, Sustained Port Order Rate Threshold, Symbol Order Rate Threshold, and Sustained Symbol Order Rate Threshold port attributes will be enforced by read pause instead of by rejects.

If Enforce Rate Limit via Pause is set and the Port Order Rate Threshold, Sustained Port Order Rate Threshold, Symbol Order Rate Threshold, or Sustained Symbol Order Rate Threshold port attributes rate limit is exceeded, the system will pause the reading of all new messages (including cancels) that exceed the the limit until the pause timer has expired. Once the pause timer has expired, the system will resume reading orders again.
