Solution Overview

Problem

Dark order block trades face issues of information leakage and gaming, which degrade market liquidity quality, necessitating improved auctioning mechanisms to maintain integrity.

Innovation Solution

Auctioning mechanisms that include automatically creating auctions based on monitored market activity, building order books, calculating a reference price, and filling orders from market participants based on this price to minimize information leakage and gaming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dark order block trades are conducted away from central exchanges, then trading large blocks of securities can be done without identifying trade details, but information leakage and gaming occur that degrade market liquidity quality

Engineering Contradiction:

Improveintegrity of dark order block tradingVSAvoidinformation leakage and gaming

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces an auction mechanism as an intermediary between dark order block traders and the broader market. This auction system acts as a controlled mediator that matches buyers and sellers through transparent pricing rules while keeping order details confidential, thereby preventing information leakage and gaming while maintaining trading integrity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes key parameters of the trading mechanism by implementing minimum fill size requirements, reference price calculations, and controlled auction timing. These parameter changes create structured trading conditions that reduce gaming opportunities while maintaining the privacy benefits of dark trading

Inventive Principle:

Principle #35Parameter changes

2Reliability

If controls are implemented to reduce information leakage and minimize gaming, then market integrity is maintained, but trading efficiency and liquidity access may be reduced

Engineering Contradiction:

Improvemarket integrityVSAvoidtrading efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-establishing auction parameters, minimum fill sizes, and reference price methodologies before trading occurs. This upfront structuring enables efficient execution during the auction process while maintaining integrity controls, as the framework is already in place rather than being imposed during trading

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The auction mechanism enables self-service trading where market participants independently submit orders and the system automatically matches them according to predetermined rules. This automation maintains market integrity through consistent application of controls while preserving trading efficiency by eliminating manual intervention

Inventive Principle:

Principle #25Self-service
