US Patent 10049404 Methods and systems to prevent adverse exchange limit effects

Methods and systems to prevent adverse exchange limit effects are disclosed. An example method of message management includes tracking, at a gateway, a transaction count of trade messages communicated to an exchange via an exchange link. The example 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. The example method includes assigning a message priority to each of a plurality of trade messages to communicate to the exchange. The example method includes communicating trade messages of the plurality of trade messages having a first message priority to the exchange when the transaction count is greater than the second transaction limit, and delaying or rejecting trade messages of the plurality of trade messages having a second message priority.
