Automated Trading Execution System with Dynamic Volume Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traders face the challenge of managing market impact and portfolio risk when executing large trades, known as the Trader's Dilemma, as these factors often conflict with each other, requiring a balance that existing systems struggle to achieve effectively.
Innovation Solution
The system determines market impact relationships and risk models for each position in a portfolio, using non-linear constrained optimization to calculate optimal Percentage of Volume (POV) trading rates, considering market and position data, user inputs, and risk aversion parameters, to execute trades in a way that minimizes both market impact and portfolio risk.

Engineering Contradiction Analysis
1Productivity
If a trader executes large volumes of trades at once, then the trading speed and productivity are improved, but the market impact increases causing price distortion to the trader's disadvantage
Solution Approach 1:
The patent divides a large trade volume into multiple smaller trades executed at discrete time intervals. The system segments the total number of shares to be traded into portions executed at specific POV rates (e.g., 10%, 20%, 30% of average daily volume) across multiple time periods, thereby reducing market impact while maintaining overall trading productivity.
Solution Approach 2:
The system dynamically adjusts the POV trading rate based on real-time market conditions, portfolio risk metrics, and remaining trade volume. The algorithm continuously monitors market impact and portfolio risk, adjusting the execution rate to optimize the balance between trading speed and market impact minimization.
2Object-affected harmful factors
If a trader slows down trade execution to reduce market impact, then the market impact is minimized, but the trading time and loss of productivity increase
Solution Approach 1:
The system implements periodic trade execution at predetermined intervals rather than continuous trading. By scheduling trades at specific time periods with defined POV rates, the system achieves systematic market impact reduction while maintaining predictable trading timelines, preventing excessive trading time extension.
Solution Approach 2:
The algorithm changes the POV trading rate parameter dynamically based on market conditions and portfolio state. By adjusting the POV rate (e.g., from 5% to 15% of average daily volume) based on real-time feedback, the system optimizes the trade-off between execution speed and market impact without unnecessarily extending trading duration.
3Reliability
If a trader makes trades to decrease portfolio risk, then the portfolio risk is minimized, but the market impact increases
Solution Approach 1:
The system continuously monitors portfolio risk metrics and market impact indicators, using this feedback to adjust the POV trading rate in real-time. When portfolio risk decreases reach target levels, the algorithm reduces the trading rate to minimize further market impact, creating a closed-loop control system that balances risk reduction with impact minimization.
Solution Approach 2:
The trading strategy dynamically adapts the execution rate based on the evolving portfolio risk profile. As risk metrics change during the trading process, the system adjusts the POV rate to achieve risk reduction objectives while minimizing market impact at each stage of the trading horizon.
4Object-affected harmful factors
If a trader makes trades to reduce market impact, then the market impact is minimized, but the portfolio risk increases
Solution Approach 1:
The system uses real-time feedback from both market impact metrics and portfolio risk measurements to adjust the POV trading rate. When market impact becomes excessive, the algorithm increases the trading rate to accelerate risk reduction, ensuring that portfolio risk objectives are met while minimizing market impact within acceptable bounds.
Solution Approach 2:
The algorithm changes the POV trading rate parameter based on the balance between market impact and portfolio risk. By adjusting this key parameter dynamically, the system optimizes the trade-off, increasing the rate when risk reduction is urgent and decreasing it when market impact becomes problematic.
