A computerized trading system includes a master node and a plurality of regional nodes, the master and regional nodes each including a processor and memory, and where the master node is communicatively coupled to each of the regional nodes over a network. The master node and regional nodes are programmed to perform a method for updating limits for each of the regional nodes, where the master node maintains a global limit and a ratio representing a proportion of the global limit allocable to each of the regional nodes. The master node allocates to each regional node a local limit that is a proportion of the global limit in accordance with the ratio, and monitors the local limit utilization at each of the regional nodes. When the master node detects one or more events, the master node allocates a new local limit to one or more of the regional nodes.
