Executable Instruction Delay Queues for Latency Arbitrage Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquidity providers in financial markets face challenges from latency arbitrageurs who exploit pricing disparities, leading to reduced liquidity and increased costs for providers trying to compete in speed, with regulatory scrutiny potentially eliminating incentives for providing liquidity.
Innovation Solution
Implementing a Liquidity Enhancing Access Delay (LEAD) system that intentionally delays the processing of new orders in a Matching System based on predefined criteria, allowing slower providers to adjust to market conditions before executing trades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated trading systems execute orders immediately upon arrival at the Matching System, then trading speed and productivity are improved, but latency arbitrageurs exploit pricing disparities causing harm to liquidity providers and reducing market stability
Solution Approach 1:
The system performs preliminary evaluation of incoming orders against delay criteria before immediate execution. The LEAD queue acts as a preliminary holding area where orders are assessed for potential latency arbitrage characteristics before being released for matching, preventing harmful rapid executions while allowing legitimate fast trades.
Solution Approach 2:
The LEAD queue serves as an intermediary mechanism between order receipt and immediate execution. This intermediate structure allows the system to buffer and evaluate orders, introducing a controlled delay that prevents latency arbitrageurs from exploiting pricing disparities while maintaining overall market efficiency.
2Speed
If liquidity providers compete by increasing system speed to match latency arbitrageurs, then response time is improved, but system complexity and costs increase
Solution Approach 1:
Instead of making the system faster to compete with latency arbitrageurs, the invention inverts the approach by intentionally slowing down specific orders through the LEAD queue. This reverse strategy prevents the need for continuous speed escalation while maintaining fairness and reducing system complexity.
3Object-affected harmful factors
If a delay queue is introduced to postpone order execution, then latency arbitrage impact is reduced, but processing time and productivity decrease
Solution Approach 1:
The system applies delay selectively rather than universally. Only orders meeting specific delay criteria are placed in the LEAD queue, while other orders execute immediately. This partial application of delay minimizes overall processing time loss while effectively countering latency arbitrage for problematic orders.
Solution Approach 2:
The system dynamically changes the processing parameter (execution timing) based on order characteristics. By evaluating each order against delay criteria and adjusting its processing time accordingly, the system optimizes the balance between preventing latency arbitrage and maintaining overall trading efficiency.
Data Source
AI summary
A system and method are provided for intentionally delaying an execution of an executable instruction by determining if a current executable instruction is received from a predefined source for which all executable instructions are to be intentionally delayed. When so, the system sets a sequence time associated with the instruction equal to a receipt time plus a delay time. The system saves the instruction in an intentional delay queue for future execution. When the current executable instruction is received from a source that is not the predefined source, the system determines if a condition for immediate processing of the current executable instruction is present. When so, the system executes the instruction immediately. Otherwise, it performs an intentional delay determination that determines whether the current executable instruction has been intentionally delayed. When the current executable instruction has been intentionally delayed, the system executes the instruction immediately.
