Aspects of the disclosure relate to order processing. A computing platform may determine that order processing for a subset of a plurality of trading pairs should be migrated from a source computing platform to a destination computing platform. The destination computing platform may configure itself to process first trading pair, and may enter a proxy mode where orders for the subset of the plurality of trading pairs are routed to the destination computing platform. The destination computing platform may receive and load order processing information corresponding to the subset of the plurality of trading pairs, and may direct the source computing platform to cease processing for the subset of the plurality of trading pairs. The destination computing platform may disable the proxy for the source computing platform, and may receive orders/process for the subset of the plurality of trading pairs.
