Trading Order Decay Mechanism for Volatility Risk Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic trading systems face challenges in managing trading orders, particularly in reducing risks associated with market volatility and conserving system resources, as they often fail to efficiently handle reserved quantities of trading orders over time.
Innovation Solution
A system that allows traders to submit orders with both displayed and reserved quantities, where the reserved quantity decays over time based on an identified decay rate, reducing exposure to unfavorable prices and freeing up system resources by gradually deleting reserved quantities from order books.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reserved quantity is maintained in the order book, then the trader's exposure to favorable prices is preserved, but the system resources are consumed and data throughput is reduced
Solution Approach 1:
The patent extracts the reserved quantity from the order book display and separates it into a distinct data structure. The displayed quantity is what is shown to market centers, while the reserved quantity is stored separately with a decay mechanism. This extraction allows the system to maintain trader exposure information without consuming system resources for displaying stale reserved quantities, thereby improving data throughput while preserving price exposure reliability.
2Productivity
If the reserved quantity is deleted immediately, then system resources are freed, but the trader's exposure to favorable prices is lost
Solution Approach 1:
The patent introduces a dynamic decay mechanism for the reserved quantity instead of immediate deletion. The reserved quantity decays over time based on a decay rate, allowing the system to gradually free up resources while maintaining trader exposure to favorable prices for a predetermined period. This dynamic approach balances resource efficiency with price exposure reliability, enabling the system to adapt to changing market conditions.
3Loss of information
If the displayed quantity is increased to show more order detail, then market transparency is improved, but the risk of exposing reserved quantities to market volatility increases
Solution Approach 1:
The patent segments the trading order quantity into two distinct components: displayed quantity and reserved quantity. The displayed quantity is what is shown to market centers to maintain transparency, while the reserved quantity is kept separate with a decay mechanism to prevent exposure to market volatility. This segmentation allows the system to provide necessary market information while protecting against the harmful effects of volatility on reserved positions.
Data Source
AI summary
A system comprises a memory operable to store a trading order for a particular quantity of a trading product, wherein a first portion of the particular quantity is a displayed quantity and a second portion of the particular quantity is a reserved quantity. The system further comprises a processor communicatively coupled to the memory and operable to disclose the displayed quantity to one or more market centers. The processor is further operable to identify a decay rate associated with the trading order. The processor is further operable to cause the reserved quantity to decay based at least in part on the identified decay rate.
