Abstract Methods and systems to prevent adverse exchange limit effects are disclosed. A method of message management includes tracking, at a gateway, a transaction count of trade messages communicated to an exchange via an exchange link. The method includes defining a first transaction limit based on the transaction count, and calculating a second transaction limit as a function of the first transaction limit, wherein the second transaction -limit is to correspond to a reserve capacity associated with the exchange link.
