Ideal Latency Floor for Electronic Trading Venues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional latency floor mechanisms in electronic trading venues do not completely eliminate the advantage of responding faster than the latency floor value, leading to ongoing incentives for market participants to invest in speed and increased operational complexity for venue operators, reducing inclusiveness and fairness in market competition.
Innovation Solution
The ideal latency floor system detects and manages races by batching messages, shuffling participant orders to ensure equal chances of winning, and employing configurable strategies for processing, thereby neutralizing the advantage of speed and promoting fair competition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional latency floor mechanisms are used, then some latency randomization is achieved, but the advantage of responding faster than the latency floor value is not completely eliminated
Solution Approach 1:
The patent segments the message processing into distinct phases: a collection phase where messages are gathered for a predetermined period, and a processing phase where messages are handled in a predetermined order independent of arrival time. This segmentation ensures that even if participants respond faster than the latency floor, their speed advantage is neutralized because processing order is determined by the collection timing window rather than individual message arrival times.
Solution Approach 2:
The system performs preliminary action by collecting messages for a predetermined period before processing them. This preliminary collection phase ensures that all messages arriving within the latency floor value are gathered together first, and then processed in a predetermined order. This preliminary action prevents faster responders from gaining an advantage, as the processing sequence is predetermined and independent of individual message arrival times.
2Ease of operation
If latency floor mechanisms are implemented, then speed competition is reduced, but operational complexity for venue operators increases
Solution Approach 1:
The patent implements periodic action by establishing a predetermined collection period for gathering messages before processing. This periodic mechanism simplifies the venue operator's task by using a time-based window approach rather than complex real-time ordering. The system collects messages during the collection period and then processes them in a predetermined order, which is easier to implement and manage compared to continuous real-time latency management.
3Productivity
If time-priority rules are used for processing messages, then processing speed is maintained, but fairness and inclusiveness are reduced
Solution Approach 1:
The patent applies dynamics by making the processing order independent of message arrival time within the collection period. Instead of static time-priority processing, the system dynamically determines processing order based on the predetermined collection timing window. This dynamic approach maintains processing speed by handling messages in batches during the collection period while ensuring fairness by neutralizing individual arrival time advantages.

AI summary
The invention relates to a system and method for providing a latency floor for an electronic trading venue in which market participants who can respond within the value the floor and choose to compete in a specific race to make or take a price may each have a substantially equal chance of winning that race. The system may detect and distinguish individual “races” that occur on an electronic trading venue. Upon detection of the first order (or message) in such a race, the system may create a batch and a timer for that race. As orders pertaining to that race are received, they are added to its batch. Upon the timer reaching a predetermined value, typically the value of the floor, the race is determined to have ended and the orders are drained from the batch for processing (e.g., against the instrument's central limit order book (CLOB)).
