Automated trading systems, also known as mechanical trading systems, allow traders to establish specific rules for both trade entries and exits that can be automatically executed via a computer.
70% to 80% of shares traded on U.S. stock exchanges come from automatic trading systems as of 2024.
Trade entry and exit rules can be based on simple conditions, such as a moving average crossover, or they can be complicated strategies that require a comprehensive understanding of the programming language specific to the user's trading platform.
Automated trading systems typically require the use of software linked to a direct access broker, and any specific rules must be written in that platform's proprietary language.
The TradeStation platform uses the EasyLanguage programming language, while the NinjaTrader platform utilizes NinjaScript.

Benefits of Automatic Stock Trading
Automated trading systems save you time and stress while empowering you to win more trades with less work.
They can process complex calculations and execute trades faster than any human trader, analyzing a multitude of market conditions and variables simultaneously.

Automated trading systems eliminate the human emotion that costs so many investors profits by adhering to a predefined set of rules.
This discipline and consistency allow the system to stick to the strategy even in volatile markets, providing a level of consistency that would otherwise be difficult for traders to maintain manually.
Traders can use historical data to evaluate the effectiveness of a trading strategy before risking actual capital, allowing for fine-tuning and adjustments to improve performance.
Automating the trading process saves considerable time, freeing up traders to focus on strategy development, research, or personal pursuits.
With options auto trading, traders don't need to monitor the markets constantly throughout trading hours, allowing them to focus on other tasks.
The system operates independently, scanning for trading opportunities and executing them based on predefined rules, reducing the burden of constant monitoring.
Setting Up an Automatic Stock Trader
Setting up an automatic stock trader can be a complex process, but it's not impossible. You'll need to choose a server-based trading platform, such as those mentioned in Example 1, which can host your automated trading system.

To get started, you'll need to decide on the key components of your system, including data analysis tools, algorithmic models, execution mechanisms, risk management protocols, and backtesting frameworks. These components are essential to creating a robust and reliable trading system, as explained in Example 4.
You can also use strategy-building "wizards" on some trading platforms to help you establish trading rules, as shown in Example 5. These wizards can simplify the process of creating a trading strategy, but keep in mind that programming your own custom indicators and strategies can offer more flexibility and potentially better results.
Here's a breakdown of the key components you'll need to consider:
- Data Analysis Tools: Process vast amounts of market data to identify potential trading signals.
- Algorithmic Models: Automate the trading process based on quantitative criteria such as stock patterns or volume changes.
- Execution Mechanisms: Execute trades swiftly and efficiently, often through direct market access.
- Risk Management Protocols: Help to minimize losses, manage volatility, and preserve capital.
- Backtesting Frameworks: Test trading strategies against historical data to assess their viability.
Establishing Rules
Establishing rules is a crucial step in setting up an automatic stock trader. You can use trading platforms with strategy-building "wizards" that allow users to select from a list of technical indicators to build a set of rules.
These wizards can help you create rules like entering a long position trade when the 50-day moving average crosses above the 200-day moving average on a five-minute chart. You can also input the type of order and when the trade will be triggered.

Many traders choose to program their own custom indicators and strategies, working closely with a programmer to develop the system. This requires more effort but allows for a greater degree of flexibility and potentially more rewarding results.
Once the rules are established, the computer can monitor the markets to find buy or sell opportunities based on the trading strategy's specifications. Depending on the specific rules, the computer can automatically generate orders for protective stop losses, trailing stops, and profit targets.
Traders can adjust these settings to suit their risk tolerance, ensuring the software trades within comfortable limits. Options auto trading platforms often include various tools to help manage risk.
Selecting Suitable Software and Tools
Selecting suitable software and tools is crucial for setting up an automatic stock trader.
Your trading software can make or break your system's efficacy, so choose wisely.
Some brokers offer their own trading platforms with automation tools, such as Interactive Brokers' Trader Workstation (TWS), which supports automated trading through their proprietary API.

You can also use algorithmic trading software that offers a more comprehensive environment for backtesting and deploying trading algorithms.
These platforms typically support multiple programming languages and offer extensive data sets for analysis.
Ensure the software you select is compatible with your trading broker's interface and offers real-time data feeds, technical indicators, and the ability to backtest and optimize your strategy.
This will save you time and effort in the long run, and help you refine your trading strategy.
