Exercise: Calculating Profit/Loss using EDSP

Scenario:

You entered a long position in a corn futures contract at a price of $5.00 per bushel. The contract size is 5,000 bushels. The EDSP for the next three days is as follows:

• Day 1: $5.20
• Day 2: $5.10
• Day 3: $5.30

Task: Calculate your daily profit/loss and your cumulative profit/loss after three days using the EDSP. Show your workings.

Techniques

Chapter 1: Techniques for Determining the EDSP

The Exchange Delivery Settlement Price (EDSP) is the cornerstone of futures contract settlement. Its accurate determination is paramount for market integrity and transparency. Several techniques are employed to calculate the EDSP, each with its own strengths and weaknesses. The choice of technique often depends on the specific characteristics of the underlying asset and the exchange's rules.

1. Volume-Weighted Average Price (VWAP): This is a common method that considers both the price and volume of transactions during a specific period, usually the last few minutes of trading. Higher volume trades have a greater influence on the final price. This technique aims to minimize the impact of potentially manipulative last-minute trades.

2. Closing Price: A simpler approach that uses the last traded price before the official market close. While straightforward, this method can be susceptible to manipulation if a large trade occurs just before the close.

3. Arithmetic Average: This method calculates the average of the prices of trades over a specified period, giving equal weight to each trade regardless of volume. This is less susceptible to manipulation by large single trades compared to VWAP but ignores the market's emphasis on volume.

4. Weighted Average of Last Trades: This method gives more weight to the last few trades before closing, acknowledging market momentum. The weights given to each trade are usually based on their position in the final trading minutes.

5. Combination Methods: Some exchanges use a combination of the above methods, often with a set of pre-defined rules for handling unusual market conditions or outliers. For instance, they may use VWAP as the primary method but revert to a closing price if the VWAP is deemed unreliable due to low trading volume or other irregularities.

Challenges and Considerations:

• Market Volatility: High volatility can make it challenging to determine a representative EDSP.
• Data Integrity: Accurate and reliable market data is crucial for the correct calculation.
• Manipulation: Sophisticated trading strategies can attempt to manipulate the EDSP. Exchanges employ robust surveillance systems to detect and prevent such attempts.
• Technological Infrastructure: The efficient and timely processing of vast amounts of trading data is crucial for the timely calculation of the EDSP.

Chapter 2: Models used in EDSP Calculation

The EDSP calculation isn't merely a simple mathematical formula; it often involves sophisticated models that handle various market dynamics and ensure fairness. While the techniques outlined in Chapter 1 provide the core calculation methods, models provide a framework for handling potential irregularities and ensuring accuracy.

1. Robust Statistical Models: These models are designed to filter out noise and outliers from the raw price and volume data. Techniques like median filters or moving averages are used to smooth out short-term price fluctuations and identify potentially manipulated trades.

2. Auction Market Models: These models are particularly relevant for markets with a distinct closing auction process. They aim to capture the true equilibrium price discovered through the final auction rather than relying solely on individual trades.

3. Time-Weighted Average Price (TWAP): This model emphasizes the time dimension by equally weighting the prices over a set time interval regardless of trading volume. This can be useful in minimizing the influence of concentrated trading periods.

4. Hybrid Models: Many exchanges employ hybrid models that combine elements of several approaches. For instance, a model might use VWAP as the primary calculation method but incorporate a robust statistical filter to remove outliers and a check against the closing price to ensure consistency.

Model Validation and Refinement:

The models used for EDSP calculation are constantly validated and refined. Exchanges monitor their performance, analyzing how well they reflect the true market price under various market conditions. This involves backtesting the models against historical data and evaluating their performance during periods of high volatility or unusual market activity. Model refinements are often made to improve accuracy and resilience to manipulation attempts.

Chapter 3: Software and Technology for EDSP Determination

The accurate and timely calculation of the EDSP requires sophisticated software and robust technological infrastructure. The process involves collecting and processing vast amounts of real-time market data, applying complex algorithms, and disseminating the result to market participants.

1. Market Data Feeds: Reliable, high-speed market data feeds are essential. These feeds provide the real-time price and volume data needed for the EDSP calculation. The quality and speed of these feeds directly impact the accuracy and timeliness of the EDSP.

2. Trading Platforms: Exchange trading platforms play a crucial role in collecting and pre-processing the trading data. They ensure data integrity and facilitate efficient data transfer to the EDSP calculation engine.

3. EDSP Calculation Engines: These are specialized software systems designed for the automated and high-speed calculation of the EDSP. These engines incorporate the chosen calculation techniques and models, handling large datasets efficiently and accurately.

4. Data Validation and Reconciliation Systems: These systems verify the integrity of the market data before the EDSP calculation. They check for errors, inconsistencies, and potential manipulation attempts.

5. Dissemination Systems: Once calculated, the EDSP must be rapidly disseminated to market participants, brokers, and other stakeholders. This typically involves real-time data feeds and messaging systems to ensure widespread and timely access.

Technological Advancements:

Technological advancements are constantly improving the accuracy, speed, and reliability of EDSP calculation. The use of distributed ledger technology (DLT) and cloud computing offers potential benefits for increased transparency, security and scalability.

Chapter 4: Best Practices in EDSP Management

Effective EDSP management is critical for maintaining the integrity and efficiency of futures markets. Several best practices ensure the accuracy, transparency, and robustness of the EDSP process.

1. Clear and Transparent Methodology: The EDSP calculation methodology should be clearly defined, publicly available, and regularly reviewed to maintain fairness and prevent manipulation.

2. Robust Data Governance: Comprehensive data governance practices, including data quality checks, validation procedures, and audit trails, are crucial to ensuring data integrity and accuracy.

3. Regular Audits and Reviews: Independent audits and regular reviews of the EDSP calculation process are essential to verify the accuracy and reliability of the results and identify potential areas for improvement.

4. Contingency Planning: Exchanges should develop robust contingency plans to handle unexpected events such as system failures, data outages, or market disruptions that could impact the EDSP calculation.

5. Market Surveillance: Active market surveillance is crucial to detect and prevent potential manipulation attempts targeting the EDSP. Sophisticated algorithms and human oversight are necessary to monitor trading activity and identify unusual patterns.

6. Regulatory Compliance: Adherence to relevant regulations and industry best practices is crucial for maintaining the integrity of the EDSP and ensuring market fairness.

7. Communication and Transparency: Open communication with market participants regarding the EDSP calculation methodology, any adjustments made, and potential irregularities is essential for fostering trust and transparency.
