Cloud Matching Engine Allocation to Mitigate Latency Arbitrage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Latency arbitrage occurs in cloud-based exchanges due to participants positioning their trading systems close to data centers, allowing them to gain a timing advantage over others, which is not mitigated by moving to cloud-based platforms.
Innovation Solution
Implement a dynamic allocation system that randomly or fairly allocates cloud-based instances of matching engines to trading sessions, preventing participants from consistently accessing geographically close resources, thus eliminating latency advantages based on location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exchanges use fixed physical data centers, then participants can access trading systems with consistent latency, but participants positioned closer to data centers gain latency arbitrage advantages
Solution Approach 1:
The patent implements dynamic allocation of matching engine instances across multiple cloud regions, where the system continuously monitors and reallocates instances based on current participant distribution and latency conditions. This dynamic approach prevents static geographic advantages from creating persistent latency arbitrage opportunities, as instances can be moved to different regions to balance access equity among participants.
Solution Approach 2:
The patent introduces a new dimension of geographic distribution by deploying matching engine instances across multiple cloud regions and zones rather than relying on a single fixed location. This multi-dimensional deployment strategy ensures that participants from different geographic locations can access trading functions with comparable latency, eliminating the single-point geographic advantage that enables latency arbitrage.
2Adaptability or versatility
If exchanges migrate to cloud-based platforms, then system flexibility and scalability improve, but latency arbitrage opportunities persist because participants can position systems in the same cloud regions
Solution Approach 1:
The patent segments the matching engine functionality into multiple independent instances distributed across different cloud regions and availability zones. This segmentation prevents any single participant from gaining advantage by positioning near one specific instance, as the system can allocate different instances to different participants based on their geographic locations and current market conditions, thereby maintaining cloud flexibility while eliminating arbitrage.
Solution Approach 2:
The patent introduces a dynamic allocation intermediary layer that sits between participants and matching engine instances. This intermediary monitors participant locations, instance performance, and market conditions to make real-time allocation decisions, ensuring that no participant can consistently exploit geographic proximity to gain latency advantages, while preserving the underlying cloud platform's flexibility and scalability.
3Loss of time
If matching engine instances are statically allocated to regions, then infrastructure costs are predictable, but participants in distant regions experience higher latency
Solution Approach 1:
The patent implements dynamic allocation of matching engine instances across multiple cloud regions and zones, where the system continuously monitors and reallocates instances based on current participant distribution and latency conditions. This dynamic approach prevents static geographic advantages from creating persistent latency arbitrage opportunities, as instances can be moved to different regions to balance access equity among participants.
4Ease of operation
If multiple cloud regions are used for matching engines, then access equity among participants improves, but system complexity and management overhead increase
Solution Approach 1:
The patent implements self-service mechanisms where the dynamic allocation system automatically monitors participant access patterns, instance performance metrics, and latency conditions across multiple cloud regions. The system autonomously makes reallocation decisions without requiring manual intervention, thereby improving access equity among participants while minimizing the operational complexity and management overhead that would otherwise be required to coordinate multi-region deployments.

AI summary
Various systems and methods for allocating computing resources, such as matching engines or order books, to participants within a cloud-based trading exchange are described. In some embodiments, the systems and methods dynamically allocate cloud-based instances (e.g., instances at different locations) of matching engines to trading sessions of assets. Such dynamic allocation can avoid, prevent, or mitigate participants gaining an advantage based on their geographic or physical location relative to the geographic location (or locations) of the instances of the matching engines. Further, such allocation of resources can be performed using randomization or other allocation techniques.
