Iceberg Order Reclip Processing for Low-Latency Stack Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exchange systems face challenges in processing large iceberg orders, which cause market shifts due to network latency and visibility, leading to unfavorable stack positions and regulatory reporting issues.
Innovation Solution
An exchange system that automatically submits reclip orders for iceberg trades at exchange system latency, using a distributed transaction architecture with unique exchange order identifiers to obscure the presence of iceberg orders in market data updates, ensuring efficient and prioritized order processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual iceberg order processes are used, then order submission is possible, but network latency increases leading to unfavorable stack positions
Solution Approach 1:
The system enables self-service automation where the exchange system automatically monitors order book conditions and submits reclip orders without requiring manual user intervention. The system self-manages the entire iceberg order process including detecting when displayed quantity reaches zero and automatically submitting new orders with updated hidden and displayed quantities, thereby eliminating network latency associated with manual processes.
Solution Approach 2:
The system performs preliminary actions by pre-configuring iceberg order parameters including hidden quantity, displayed quantity, and reclip conditions before order execution. The exchange system prepares and queues reclip orders in advance, so that when the trigger condition is met (displayed quantity reaches zero), the reclip order is immediately submitted without delay, achieving favorable stack positions.
2Object-affected harmful factors
If iceberg orders are submitted with hidden quantities, then market impact is reduced, but the presence of iceberg orders should be obscured in market data
Solution Approach 1:
The system segments the total order quantity into hidden quantity and displayed quantity components. The hidden quantity portion remains concealed from market data while the displayed quantity is visible. When the displayed quantity is depleted, the system segments another portion from the hidden quantity to become the new displayed quantity, maintaining market impact reduction while managing information visibility through controlled segmentation.
Solution Approach 2:
The exchange system acts as an intermediary that manages the iceberg order structure, separating the hidden quantity from the displayed quantity in market data feeds. The intermediary mechanism ensures that only the displayed quantity appears in market data updates, while the hidden quantity remains obscured, thereby protecting order presence while enabling controlled market participation.
3Productivity
If automated reclip orders are implemented, then latency is reduced, but system complexity increases
Solution Approach 1:
The automated reclip order system implements self-service functionality where the exchange system autonomously monitors order book conditions, detects when displayed quantity reaches zero, and automatically submits reclip orders without external intervention. This automation eliminates manual processing delays and achieves minimal latency, with the system managing its own order lifecycle including quantity tracking and reclip submission.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring the order book to detect when the displayed quantity of an iceberg order reaches zero. This feedback trigger automatically initiates the reclip order submission process, creating a closed-loop control system that responds to market conditions in real-time, thereby achieving rapid automated response with minimal latency.
Data Source
AI summary
Techniques are disclosed herein for iceberg order processing by an exchange system that includes storing a first representation of an iceberg order requested by a user in an order book and automatically causing a second representation to be stored for the iceberg order in the order book after the displayed quantity associated with the first representation is depleted/zeroed or otherwise below a predetermined threshold following execution of an associated trade. The second representation of an iceberg order can be referred to as a reclip order, and N number of such reclip orders can be stored/accepted in this manner by the exchange system until a hidden/reserve quantity (also referred to herein as a remaining iceberg quantity) is zero or the user who originated the iceberg order submits a cancel request.
