What is a Trading Algorithm?

Trading Algorithm - How to Create a Trading Algorithm

A trading algorithm, or trading bot, is a computer program that follows predefined rules to execute trades in financial markets. These algorithms can be as simple as buying or selling a stock when it hits a specific price or as complex as using machine learning to predict future price movements based on market patterns and historical data.

At its core, a trading algorithm automatically monitors markets and executes buy or sell orders when specific criteria are met. This removes the need for manual intervention and allows trades to be placed precisely and quickly. Algorithmic trading can be used in various markets, including:

Stocks
Commodities
Forex
Cryptocurrencies

Popular Trading Strategies for Trading Algorithms

Some of the most common strategies used in trading algorithms include:

Trend Following

Buying assets when prices are rising and selling them when prices are falling.

Arbitrage

Exploiting price differences for the same asset across different markets.

Mean Reversion

Assuming that prices will revert to their historical average after a significant deviation.

Algo-Trading Time Scales

Much of today’s algorithmic trading is high-frequency trading (HFT), which attempts to capitalize on placing orders rapidly across multiple markets and multiple decision parameters based on preprogrammed instructions.

Who Uses Trading Algorithms?

Algo-trading is used in many forms of trading and investment activities, including:

Mid- to long-term investors or buy-side firms

These industries use algorithmic trading to purchase stocks in large quantities when they do not want to influence stock prices with discrete, large-volume investments:

Pension funds
Mutual funds
Insurance companies

Short-term traders and sell-side participants

Algo trading benefits from automated trade execution and helps create sufficient liquidity for sellers in the market, such as:

Market makers (brokerage houses)
Speculators
Arbitrageurs

Systematic traders

Algorithmic trading provides a more systematic approach to active trading than methods based on trader intuition or instinct. Some elements of it are as follows:

Programing their trading rules and letting the program trade automatically is more efficient.

How Can Someone Benefit from Algorithmic Trading?

Crypto Algorithm - How to Create a Trading Algorithm

Speed and Efficiency

Speed is one of the main advantages of algorithmic trading. Algorithms can execute trades in milliseconds, allowing them to capitalize on even the slightest market movements and inefficiencies. Because they can process vast amounts of market data much faster than humans, an algorithm can quickly determine a favorable trading opportunity and execute orders before it vanishes.

This is particularly useful in today’s fast-paced markets, where conditions can change within seconds.

Reduced Emotional Bias

Human traders are prone to emotional decision-making, which can lead to impulsive trades based on fear or greed. Using a trading algorithm, decisions are made purely based on logic and data, eliminating emotional bias and leading to more disciplined trading strategies.

Backtesting and Optimization

Before implementing an algorithm in live trading, traders can backtest their strategy using historical data. This allows them to see how the algorithm would have performed under different market conditions, identify potential weaknesses, and refine the plan for better results.

24/7 Trading

Unlike human traders, who need breaks and sleep, trading algorithms can run continuously. This is particularly useful in markets that operate around the clock, such as forex or cryptocurrencies, where trading opportunities may sometimes arise.

10 Common Algorithmic Trading Strategies Used in Algo-Trading

Trading - How to Create a Trading Algorithm

1. Trend-Following Strategies: The Most Popular Algorithmic Trading Strategy

Trend-following strategies are among the most popular types of algorithmic trading strategies. The algorithms follow moving averages, price level movements, channel breakouts, and related technical indicators to identify and exploit trends in the market.

Trend-following strategies are popular because they are simple to implement, can be used in any market to capitalize on rising and falling prices, and can produce consistent returns over time.

2. Arbitrage Opportunities: The Quick Profit Strategy

Arbitrage opportunities exploit price discrepancies of the same asset across different markets or related assets, such as stocks and futures.

An algorithmic trading strategy can quickly identify and execute arbitrage opportunities to lock in quick profits before the price differential disappears.

3. Index Fund Rebalancing: The Predictable Trading Strategy

Index funds periodically rebalance their portfolios to align their holdings with a specified benchmark. These trades create predictable, profitable opportunities for algorithmic traders who can identify and execute trades on the stocks involved in the rebalancing before the index fund completes its rebalancing.

4. Mathematical Model-Based Strategies: The Complex Approach

Mathematical model-based strategies use proven market models to identify trading opportunities. One example is delta-neutral trading, which involves options and their underlying securities.

Delta-neutral strategies seek to profit from changes in volatility by creating positions that offset the risk of price movements in the underlying security.

5. Trading Range (Mean Reversion): The Counter-Trend Strategy

Mean reversion is based on the idea that prices move in trends but eventually revert to their mean. Trading range or mean reversion strategies exploit this phenomenon by identifying an asset’s price range and automatically executing trades when the price breaks in and out of the defined range.

6. Volume-Weighted Average Price (VWAP): The Market Impact Strategy

A volume-weighted average price (VWAP) algorithm breaks large orders into smaller chunks to minimize market impact. The strategy uses historical volume data to determine how to time and release the smaller orders, ensuring the execution price is as close as possible to the VWAP.

7. Time Weighted Average Price (TWAP): The Time Impact Strategy

Time-weighted average price (TWAP) algorithms also break up large orders to minimize market impact. However, instead of using volume data, TWAP algorithms divide the order into equal parts to be executed over a specified time.

The goal is to achieve an average execution price as close as possible to the price at the start of the period.

8. Percentage of Volume (POV): The Adaptive Strategy

Percentage of volume (POV) algorithms also break large orders into smaller chunks to minimize market impact. However, instead of dividing the order into equal parts, PO algorithms calculate the size of the smaller orders based on the volume of trading occurring in the market.

Until the order is filled, the algorithm sends partial orders according to the defined participation ratio and adapts to changing market conditions to minimize impact.

9. Implementation Shortfall: The Cost Minimization Strategy

The implementation shortfall strategy aims to minimize an order’s execution cost by trading off the real-time market. This saves the order’s cost and benefits from the opportunity cost of delayed execution.

The strategy will increase the targeted participation rate when the stock price moves favorably and decrease it when it moves adversely.

10. Beyond the Usual Trading Algorithms: The Sniffing Algorithms

A few special classes of algorithms attempt to identify happenings on the other side. These sniffing algorithms, used, for example, by a sell-side market maker, have the built-in intelligence to recognize the existence of any algorithms on the buy side of a large order.

Such detection through algorithms will help the market maker identify ample order opportunities and enable them to benefit by filling the orders at a higher price. This is sometimes identified as high-tech front-running.

Why Should You Learn Algorithmic Trading?

Person Using Computer - How to Create a Trading Algorithm

Algorithmic trading, also known as automated or systematic trading, uses computer programs to trade financial instruments at speeds and frequencies that are impossible for human traders. As markets become more electronic, algorithmic trading increasingly takes over traditional manual trading. For example, a recent study showed that more than 70% of trades in U.S. equity markets are now executed by algorithms. This trend has been observed across various asset classes and global markets.

As trading and financial markets embrace technological advancements, algorithmic trading and high-frequency trading are gaining widespread acceptance across global exchanges. Within a decade, they have become the predominant trading methods in developed markets and are swiftly gaining traction in emerging economies. For a trader, it is imperative to know that learning algorithmic trading gives you an advantage over manual trading amidst this technological shift.

The Growing Demand for Algorithmic Trading

With the rapid growth of algorithmic trading, there is a rising demand to “learn algorithmic trading.” The reason is the growing “demand for algorithmic trading” in the financial sector. Reputed global banks and investment giants are investing in Quants for the future of trading. In 2019, Bloomberg reported, “JPMorgan Arms Coders With Trading Licences as Quants Advance.”

In early 2020, Forbes reported: Citigroup started planning to hire 2,500 programmers for its trading and investment banking units. Citigroup’s 75% of trades were electronic by 2019. Goldman Sachs began to hiring Coders, Data Scientists, and Engineers for their Trading floor. Research states, “Approximately 80% of investments are either quant-based or fully passive, with only one-fifth of trades actively plotted out by sentient lifeforms.”

The Popularity Of Algorithmic Trading

The growth of algorithmic trading is also reflected in the increasing popularity of online communities dedicated to the topic. For instance, as of August 2024, the subreddit Algo Trading on Reddit has 1.8 million active users, with thousands joining daily.

The growth indicates people’s interest in this growing domain. Hence, banks, investors, and financial institutions are drawn to this field, which is rising quickly and has been adopted globally.

Advantages and Disadvantages of Algorithmic Trading

Woman Using Laptop - How to Create a Trading Algorithm

The Upsides of Algorithmic Trading

Algorithmic trading comes with several perks, including:

Speed
Accuracy
Reduced emotional trading

Algorithmic Trading Executes Orders at Lightning-fast Speeds

The faster a trading strategy can react to market conditions, the better. Algo-trading automates this process, allowing traders to benefit from even the smallest price changes without entering trades manually. This can help capture profits before the market has a chance to react.

Algorithms Can Help Improve Trading Accuracy

Not only can they reduce human errors associated with manually entering trades, but they can also execute orders with precision. This means getting the best prices rather than settling for worse prices due to human error or market fluctuations.

Algo-trading Can Remove the Emotional Aspect of Trading

Financial markets are influenced by human behavior, and as humans, traders can become emotionally attached to their positions. Also, as market conditions change, traders can panic, becoming fearful or greedy, negatively impacting their decision-making abilities. Algorithms can take the emotion out of trading by following a predetermined set of rules to execute trades.

The Downsides of Algorithmic Trading

Of course, there are also several drawbacks or disadvantages of algorithmic trading to consider.

Algo-trading Dystems Can be Complex to Create and Implement

Even if you want to use an existing trading algorithm, learning how it works and customizing it for your needs can take time.

Algo-trading Systems Depend on Technology

Any technical failures can disrupt your trading and lead to losses. Algorithms can also malfunction, leading to costly erroneous trades. In addition, there is a risk of market impact. Large algorithmic trades can significantly impact market prices, which can result in losses for traders who are not able to adjust their trades in response to these changes.

Algo-trading Systems Lack Human Judgment

Algorithms rely on mathematical models and historical data, meaning they do not consider the subjective and qualitative factors that can influence market movements. This lack of human judgment can disadvantage traders who prefer a more intuitive or instinctive approach to trading.

How Can a VPS Service Improve Your Trading?

A VPS is a virtual private server. To understand it, it is necessary to recognize its place within the web hosting environment.

Shared Hosting

The most common arrangement in web hosting is referred to as shared hosting. This is a physical server shared between different customers. It is the most economical option and is considered the entry-level of hosting. Websites share the server’s key resources, with each typically having a limit on the total amount of server resources available, such as:

CPU
RAM,
Disk space

Shared hosting provides a one-size-fits-all type of hosting for beginners, though it is restricted due to the low level of customization.

Dedicated Server Hosting

At the other end of the spectrum, we have what’s known as dedicated server hosting. Here, an individual customer gains access to an entire server. Clients maintain complete control over the machine, allowing freedom to optimize to their unique requirements, though it comes with a hefty price tag. In recent years, virtual private servers (VPS) have become increasingly popular among traders in the financial markets. A VPS offers many advantages for traders, including:

High-speed and reliable internet connectivity
Uninterrupted trading operations
The ability to run automated trading strategies 24/7

The Best Practice Guide for Trading on VPS

Trading on a VPS can provide traders with several powerful features to enhance their trading experience. Here are some of the key benefits and features of trading on a VPS:

Enhanced Reliability and Uptime

One of the most significant advantages of trading on VPS is its enhanced reliability.

Optimize Network Connectivity

Network connectivity plays a crucial role in trading. To ensure a smooth trading experience, we recommend you optimize your VPS’s network connectivity. Here are a few different ways to do this:

Choose a Reliable Internet Service Provider (ISP): To ensure smooth trading operations, select a reliable Internet Service Provider (ISP) offering low latency and high-speed internet connections. A stable and fast internet connection is essential for real-time data transmission and rapid execution of trades.
Optimize Router Placement: Your router’s placement plays a significant role in network performance. To maximize connectivity, position your router in a central location, away from obstructions such as walls or furniture. This allows for better signal distribution throughout your trading area.
Use a Wired Connection for VPS: Wired connections offer lower latency and higher speeds, reducing the chances of data packet loss during transmission. You can ensure a stable and reliable network connection for trading on your VPS by directly connecting your computer to the router via an Ethernet cable.
Regularly Monitor and Optimize Network Settings: Ensure your VPS is configured to prioritize trading applications, allocating sufficient bandwidth. Consider implementing Quality of Service (QoS) settings on your router to prioritize trading data over other internet activities, preventing potential delays or interruptions.

Install Reliable Trading Software

When trading on a VPS, installing reliable and trusted trading software is essential. Choose a platform compatible with your trading strategy that provides features like real-time market data, advanced charting tools, and order execution capabilities.

Research and Choose Trusted Trading Software: Look for software specifically designed for trading with a proven track record of reliability and performance. Read reviews, seek recommendations from fellow traders, and consider the software’s features, user interface, and compatibility with your trading strategy. Some of the best trading software are QuantVPS, MetaTrader 4 & 5, cTrader, NinjaTrader, TradeStation, and Interactive Brokers Trader Workstation.
Ensure Compatibility and Optimal Configuration: Check the software’s system requirements and ensure that your VPS meets or exceeds them. Additionally, consider the optimal configuration settings recommended by the software provider. Adjusting settings such as memory allocation, CPU usage, and network protocols can enhance the performance and stability of the trading software on your VPS.
Regularly Update and Maintain Your Trading Software: Track software updates provided by the vendor and install them promptly. Updates often include bug fixes, feature enhancements, and security patches that can improve the trading experience and protect your VPS from potential vulnerabilities.

It’s essential to note that the best trading software for you will depend on your specific trading goals, strategies, and preferences. Before deciding, it’s recommended that you explore and evaluate different platforms, considering factors such as ease of use, available features, reliability, and customer support.

Maintain Proper Security Measures

Security is paramount when trading on a VPS. Implement robust security measures to protect your trading activities and sensitive information. Use strong and unique passwords for your VPS login and trading platform accounts. Regularly update your antivirus software, firewall, and operating system to prevent potential security breaches.

Backup Trading Data

It is crucial to regularly back up your trading data to avoid any loss in the event of hardware or software failures. Set up automated backups of your trading platform settings, indicators, templates, and trade history. For added security, consider storing the backups on external storage devices or cloud-based solutions.

Monitor System Performance

Keep a close eye on your VPS’s performance to ensure optimal trading conditions. Monitor the CPU and memory usage, network latency, and disk space utilization. If you notice any performance issues, investigate the cause and take the necessary steps to resolve them. Regularly restart your VPS to clear any accumulated resources and maintain optimal performance.

Can ChatGPT Write a Trading Algorithm?

Person Looking at Code - How to Create a Trading Algorithm

Yes, ChatGPT can assist in writing a trading algorithm. The AI can provide sample code, suggest improvements, or explain concepts. ChatGPT can only execute trades or create complete trading systems with human oversight and programming knowledge.

Step-by-Step: Using ChatGPT to Write Trading Algorithms

To use ChatGPT to write options trading scripts, you must first access the model through an API or OpenAI’s GPT-3 Playground. You’ll also want to get comfortable with a brokerage that allows direct plug-ins of a script into their interface so that you can fully automate your trading process and get the most out of the trading algorithm. Three solid brokerages that allow this and still allot for excellent order execution are:

IBKR
Thinkorswim
Tradier

We have no affiliation with any of them. Thinkorswim, in particular, offers a solid paper trading platform that you can use to test these strategies risk-free with real market data.

Once you have access to the model and have become familiar with your brokerage of choice, you can input your desired trading strategy and parameters, and ChatGPT will generate code based on your inputs. Then, you can test the script using historical market data and make any necessary adjustments before using it in live trading.

A Simple Starter Script: QQQ Strategy

For a simple starter script, let’s look at the RSI rule. For the uninitiated, RSI — or the relative strength indicator — attempts to depict when a security is oversold or overbought and by how much. A simple rule of thumb for reading RSI is that when the RSI is below 30, security is oversold and prone to bounce.

Likewise, when the RSI is over 70, the security is overbought and prone to take a pause. With that in mind, let’s make a rudimentary script that uses QQQ as the target and at-the-money options as the tool.

A More Complex Strategy: SPY Strategy

We’ll ask ChatGPT to write a nuanced MACD strategy for a more complex strategy, using another indicator Bollinger Bands as confirmation. This is where ChatGPT shines — no matter how complex the task, AI can get it done. For those who understand and are willing to trade nuanced strategies like this, it can be a pain to hunt down these opportunities and pounce on them immediately. With ChatGPT, one could theoretically set this script up on multiple high-liquidity tickers.

A Specific Strategy: NVDA Strategy

Here’s an example of a more specific strategy with a 60% win rate over the last 10 years, including 40 total instances, with an average return of +2.56% when used with shares. When the strategy wins, the average return is +7.49%.

The strategy is simple: 15 days before earnings, buy at-the-money call options in Nvidia, expiring the week following earnings. Then, before the report is released, sell the options.

In this strategy, we aren’t looking to trade the earnings themselves, just the run-up. With a solid performance over the past 10 years, ChatGPT can execute this specific strategy.
