In this article, Vardaan CHAWLA (ESSEC Business School, Master in Strategy and Management of International Business (SMIB), 2020-2023) shares a case study on real-time risk management in the trading arena.

As an individual investor venturing into the dynamic world of financial markets, it’s crucial to understand and implement effective risk management strategies. The following article, explores the key principles and techniques to safeguard your investments and navigate the potential risks.

Financial markets are very dynamic, interesting, and filled with opportunities and risks. Learning to manage risks in the always-changing world of financial markets is crucial. In the following article I discuss the effective methods to manage, navigate, and avoid risk while dealing in financial markets to help you make informed decisions and safeguard your money.

Understanding Your Risk Tolerance

The first principle of effective risk management is self-awareness. Before diving into financial markets one must assess one’s own risk tolerance meaning the amount of losses you are able to manage comfortably.

Ask yourself critical questions:

  • How much capital can I realistically afford to lose?
  • How would a significant loss impact my financial well-being?
  • Am I prone to emotional decision-making during market fluctuations?

After answering these questions you can start making your trading and risk management strategies and techniques. A very aggressive investor will be open to taking a high amount of risk with more potential results while a conservative investor will be the opposite, low risk with less potential returns. One must invest based on their own loss tolerance.

Core Risk Management Strategies

Once you understand your risk tolerance, equip yourself with these key risk management strategies:

  • Position Sizing: This describes how much capital is devoted to a specific deal. Starting small is a vital notion, particularly for novices. A typical place to start is with 1% to 2% of your entire portfolio for each deal. With a diversified portfolio, you can progressively raise position size as your experience and risk tolerance permits.
  • Stop-Loss: Stop orders are vital instruments for safeguarding your investment. To limit potential losses if the market swings against your position, a stop-loss order automatically sells an asset when the price hits a predefined level (lower than the current market price). It’s critical to create stop-loss levels that balance possible asset recovery with risk minimization.
  • Take Profit: Limit orders work similarly to stop-loss orders in that they automatically lock in profits by selling an asset when the price hits a predefined level (higher than the current market price). This lessens the chance of losing gains if the market turns south. To safeguard your earnings and resist the need to cling to a winning position for too long, use take-profit orders wisely.
  • Diversification: Avoid putting all of your money in one place. Distribute your investments throughout several industries, sectors, and asset classes. This lessens the effect that a fall in one asset will have on the value of your entire portfolio. Diversification makes your portfolio more stable and less vulnerable to changes in the market.
  • Risk-Reward Ratio: This measure contrasts the possible gain with the possible loss on a certain transaction. Seek for transactions where the possible profit margin outweighs the potential loss margin. A better risk profile is indicated by a greater ratio. Prior to making a trade, evaluating the risk-reward ratio will help you make well-informed judgments regarding potential gain vs downside.

The figures below illustrate how take-profit and stop-loss can be implemented for a given stock (Meta around August 15,2024). Two orders are sent to the market (at the same time): a sell limit order with a limit price of $290 and a stop order with a trigger price of $280. Note that it is not always possible to place both a limit order an stop order at the same time (it depends on the brokers or trading platforms).

In Figure 1, the stock price stays below the limit price and above the trigger price.

Advanced Risk Management Techniques

As you gain experience, consider incorporating these advanced techniques:

  • Hedging: This is the process of offsetting possible losses in your underlying holdings by employing derivative instruments, such as option contracts. Before putting hedging methods into practice, careful thought and comprehension are necessary because they can be complicated.
  • Volatility Targeting: This strategy modifies the overall risk exposure of your portfolio in response to fluctuations in the market. You may lower the sizes of your positions or devote more capital to less volatile assets during times of high volatility. On the other hand, you may decide to take on larger positions or invest in riskier assets during times of low volatility.

Disciplined Execution: The Key to Success

Risk management is not just about having the right tools; it’s about disciplined execution. Here are some essential practices to cultivate:

  • Trading Plan: One must work meticulously in developing a comprehensive trading plan that clearly defines your entry, exit, risk management strategies, and what you aim to achieve from trading and avoid emotional and impulsive decision-making.
  • Monitoring and Adjustment: You must also regularly monitor your portfolio and be updated on financial news in order to prepare for potential future losses or opportunities. To maximize your gains utilize Stop loss orders and take profit orders and adjust your trades and position as and when needed.
  • Emotional Control: When we receive surprise losses or surprise gains we are inclined to make emotional and impulsive decisions that can lead to further future losses. The trader must always make decisions with a calm composed mind to make sound decisions.

By adopting these risk management principles and maintaining disciplined execution, you can navigate the real-time financial markets with greater confidence and minimize the possibility of significant losses. Remember, risk management is an ongoing process that requires constant evaluation and adaptation.

High-frequency trading and limit orders

High-frequency trading and limit orders

Clara PINTO

In this article, Clara PINTO (ESSEC Business School, Master in Strategy & Management of International Business (SMIB), 2020-2023) explains about high frequency trading in a dynamic limit order market.

What is High-frequency trading (HFT)?

While the adage “time is money” applies to almost all economic operations, the rapid spread of computerized trading has carried this quote to its final extreme. High-frequency trading (HFT) is a type of algorithmic trading that relies on advanced computer programs to make trading decisions and execute trades in a matter of milliseconds. HFT has become increasingly popular in recent years, particularly in dynamic limit order markets (“A dynamic limit order market with fast and slow traders”, European Central Bank), where the bid and ask prices of securities are constantly changing. This allows them to take advantage of small price discrepancies in the market and generate profits on a large scale, this method known as statistical arbitrage, involves traders looking for temporary pricing inconsistencies across different exchanges and capitalize on it, using ultra-fast transactions.

What Exactly Is a Limit Order?

A limit order is an instruction to buy or sell a security at a specified price or better. For example, a trader may place a buy limit order for a stock at $50, meaning he or she is willing to buy the stock only if it is available at that price or lower. Similarly, a sell limit order may be placed at $60, meaning the trader will sell the stock only if the price is at that level or higher.

HTF and Limit Order

High-frequency trading (HFT) and limit orders are closely linked, as HFT traders often rely on limit orders to execute their trades. In fact, limit orders are a key component of many HFT trading strategies. HFT traders often use limit orders in conjunction with advanced algorithms to identify market trends and execute trades at lightning-fast speeds. They may place many limit orders at various prices to take advantage of small price movements in the market and use sophisticated algorithms to determine the best time to execute their trades.

However, the use of limit orders in HFT trading can also have downsides. For example, the large number of limit orders placed by HFT traders can lead to increased volatility in the market, as these orders can cause sudden price movements, for example flash crash when the prices of stocks or commodities suddenly plunges but then quickly recovers. Hence, the use of limit orders in HFT trading can also have downsides, and it is important for regulators to monitor HFT activity and ensure that it does not cause market instability or unfair trading practices.

Why should I be interested in this post?

For many business school students, finance and trading are part of the most preferred jobs. Understanding the trends in high-frequency trading is now a requirement for future institutional investors. Being quick allows traders to adjust outstanding limit orders in response to news arrivals when working with “slow” market players who experience a relative loss in bargaining power, leading them to strategically submit limit orders with a lower execution probability, limiting trade.

Understanding the Order Book: How It Impacts Trading

Understanding the Order Book: How It Impacts Trading

Federico De ROSSI

In this article, Federico DE ROSSI (ESSEC Business School, Master in Strategy & Management of International Business (SMIB), 2020-2023) talks about the order book and explains its role in financial markets.

Introduction

Understanding the order book is critical when it comes to trading in financial markets. In this article, we’ll go over what an order book is and how it affects trading.

What is an order book?

An order book for a stock, currency, or cryptocurrency is a list of buy and sell limit orders for that asset. It shows the pricing at which buyers and sellers are willing to negotiate, as well as the total number of orders available at each price. The order book is a necessary component of every trading platform since it gives a snapshot of the current market situation, of the price of the assets, and of the liquidity of the market. Thus, it is a crucial tool for traders who want to make informed decisions when entering or exiting deals.

How does an order book work?

The order book is a constantly updated record of buy and sell orders. When a trader puts a limit order, it is placed in the order book at the stated price. As a result, there is a two-sided market with distinct prices for buyers and sellers.

The order book is divided into two sections: bid (buy) and ask (sell). All open buy orders are displayed on the bid side, while all open sell orders are displayed on the ask side. The order book also shows the total volume of buy and sell orders at each price level.

In Tables 1 and 2 below, we give below two examples of order book from online brokers. We can see the two parts of the order book side by side: the “Buy” part and the “Sell” part. Every line of the order book corresponds to a buy or sell proposition for a give price (“Buy” or “Sell” columns) and a given quantity (“Volume” columns). For a given line there may be one or more orders for the same price. When there are several orders, the quantity in the “Volume” column is equal to the sum of the quantities of the different orders. Associated to the order book, there is often a chart which indicates the cumulative quantity of the orders in the order book at a given price. This chart gives an indication of the liquidity of the market in terms of market spread, market breadth, and market depth (see below for more explanations about theses concepts).

The “Buy” and “Sell” parts of the order book can be presented side by side (Table 1) or above each other (Tables 2 and 3) with the “Sell” part (in red) above the “Buy” part (in green) as the price limits of the sell limit orders are always higher than the price limits of the buy limit orders.

Table 3. Example of an order book (buy and sell parts presented next to each other).

In a typical order book, the buy side is organized in descending order, meaning that the highest buy orders (i.e., the orders with the highest bid prices) are listed first, followed by the lower buy orders in descending order of price. The highest buy order in the book represents the best bid price, which is the highest price that any buyer is currently willing to pay for the asset.

On the other side of the order book, the sell side is organized in ascending order, with the lowest sell orders (i.e., the orders with the lowest ask prices) listed first, followed by the higher sell orders in ascending order of price. The lowest sell order in the book represents the best ask price, which is the lowest price that any seller is currently willing to accept for the asset.

This organization of the order book makes it easy for traders to see the current market depth and the best available bid and ask prices for an asset. When a buy order is executed at the best ask price or a sell order is executed at the best bid price, the order book is updated in real-time to reflect the new market depth and the new best bid and ask prices.

Table 4 below represents how the order book (limit order book) in trading simulations the SimTrade application.

The role of the order book in trading

As mentioned before, the order book is incredibly significant in trading. It acts as a market barometer, delivering real-time information about the supply and demand for an asset. Traders can also use the order book to determine market sentiment. If the bid side of the order book is strongly occupied, for example, it could imply that traders are optimistic on the asset. Thanks to the data in the order book, traders can get different information out of it.

Three characteristics of the order book

Market spread

The market spread, also known as the bid-ask spread, is the difference between the highest price a buyer is willing to pay for an asset (the bid price) and the lowest price a seller is willing to accept (the ask price) at a particular point in time.

The market spread is a reflection of the supply and demand for the asset in the market, and it represents the transaction cost of buying or selling the asset. In general, a narrow or tight spread indicates a liquid market with a high level of trading activity and a small transaction cost, while a wider spread suggests a less liquid market with lower trading activity and a higher transaction cost.

Market breadth

Market breadth is a measure of the overall health or direction of a market, sector, or index. It refers to the number of individual stocks that are participating in a market’s movement or trend, and can provide insight into the underlying strength or weakness of the market.

Market breadth is typically measured by comparing the number of advancing stocks (stocks that have increased in price) to the number of declining stocks (stocks that have decreased in price) over a given time period. This ratio is often expressed as a percentage or a ratio, with a higher percentage or ratio indicating a stronger market breadth and a lower percentage or ratio indicating weaker breadth.

For example, if there are 1,000 stocks in an index and 800 of them are increasing in price while 200 are decreasing, the market breadth ratio would be 4:1 or 80%. This would suggest that the market is broadly advancing, with a high number of stocks participating in the upward trend.

Market depth

Finally, market depth is a measure of the supply and demand of a security or financial instrument at different prices. It refers to the quantity of buy and sell orders that exist at different price levels in the market. Market depth is typically displayed in a market depth chart or order book.

It can provide valuable information to traders and investors about the current state of the market. A deep market with large quantities of buy and sell orders at various price levels can indicate a liquid market where trades can be executed quickly and with minimal impact on the market price. On the other hand, a shallow market with few orders at different price levels can indicate a less liquid market where trades may be more difficult to execute without significantly affecting the market price.

Analyzing order book data

Data from order books can be used to gain insight into market sentiment and trading opportunities. For example, traders can use the bid-ask spread to determine an asset’s liquidity. They can also examine the depth of the order book to determine the level of buying and selling interest in the asset. Traders can also use order book data to identify potential trading signals. For example, if the bid side of the order book is heavily populated at a certain price level, this could indicate that the asset’s price is likely to rise. On the other hand, if the ask side is heavily populated at a certain price level, it could indicate that the asset’s price is likely to fall.

Benefits of using order book data for trading

Using order book data can provide traders with a number of advantages.

For starters, it can be used to gauge market sentiment and identify potential trading opportunities.

Second, it can assist traders in more effectively managing risk. Traders can identify areas of support and resistance in order book data, which can then be used to set stop losses and take profits.

Finally, it can aid traders in the identification of potential trading signals. Traders can identify areas of potential buying and selling pressure in order book data, which can then be used to enter and exit trades.

How to use order book data for trading

Traders can use order book data to gain a competitive advantage in the markets. To accomplish this, they must first identify areas of support and resistance that can be used to set stop losses and profit targets.

Traders should also look for indications of buying and selling pressure in the order book. If the bid side of the order book is heavily populated at a certain price level, it could indicate that the asset’s price is likely to rise. On the other hand, if the ask side is heavily populated at a certain price level, it could indicate that the asset’s price is likely to fall.

Finally, traders should use trading software to automate their strategies. Trading bots can be set up to monitor order book data and execute trades based on it. This allows traders to capitalize on trading opportunities more quickly and efficiently.

Conclusion

To summarize, the order book is a vital instrument for financial market traders. It gives real-time information about an asset’s supply and demand, which can be used to gauge market mood and find potential trading opportunities. Traders can also utilize order book data to create stop losses and take profits and to automate their trading techniques. Traders might obtain an advantage in the markets by utilizing the power of the order book.
