EAsiScript enables you to define sophisticated trading strategies through a clear and flexible syntax. At its core, EAsiScript uses expressions combining functions, operators, and indicators to drive trade decisions - from entry and exit points to stop losses and take profits. This guide will teach you step by step how to write effective scripts, with a focus on practical examples demonstrating key concepts like the ternary operator (?:), logical AND (&&), and logical OR (||) operators.

Best Practices for Writing Scripts

When writing scripts in EAsiScript, following established coding practices will help you create more reliable and maintainable trading strategies. These best practices focus on proper syntax, correct use of variables and functions, and clear logical structure. By following these guidelines, you’ll avoid common coding errors and create scripts that are easier to test and modify.

Use Provided Variables:

Replace raw values like 1 or -1 with the predefined variables Bullish and Bearish:
- Bullish = 1: Indicates a buy signal or bullish trend.
- Bearish = -1: Indicates a sell signal or bearish trend.
Example: Signal('MA1') == Bullish ? Ask() : 0

Leverage the Point Variable for Scaling:
- Always multiply numeric adjustments by Point to ensure they are scaled correctly according to the symbol’s price units.
Example: ATR1(1) > 15 ? Low(1) - 20 * Point : Low(1) - 10 * Point
Explicitly Define Shifts for Functions:
- Functions like Close, Open, High, and Low require a shift parameter. The default is 1, but specifying it explicitly improves clarity.
Example: Close(1) > Open(1) ? Ask() : 0
Avoid Invalid Functions:
- Use valid functions like SL() instead of invalid ones like StopLoss().
- Valid Functions: Ask(), Bid(), SL(), Signal(), Trend().
- Invalid Examples: StopLoss(), Price().
Combine Indicators and Price Data:
- Create powerful scripts by combining indicator signals with price conditions.
Example: Trend('MA1') == Bullish && Close(1) > Open(1) ? Ask() : 0

Tips for Writing Scripts

Before diving into script writing, it’s helpful to understand some practical approaches that can make your development process smoother and more effective. While the Best Practices section covers the technical aspects of writing scripts, these tips focus on the development process itself, common pitfalls to avoid, and strategies for testing and implementing your trading logic. Whether you’re writing your first script or developing complex strategies, these guidelines will help you build more reliable and maintainable trading systems.

Test Individual Components First

Write and test entry conditions separately before combining
Verify indicator signals independently
Test time filters alone before adding to strategies

Common Mistakes to Avoid

Don’t forget to enable indicators in the Indicators List
Remember shift=1 means last completed bar, not current bar
Check you’re using Ask() for buys and Bid() for sells

Debugging Tips

Use single conditions first, then build up with AND (&&)
Test time windows with simple entry conditions
Verify indicator buffer numbers match your settings

Development Process

Start with entry logic
Add initial stop loss
Test basic exits
Add trailing stops and breakeven last
Fine-tune with take profit levels

Risk Management

Always test stop loss logic independently
Verify SL is appropriate distance from entry
Test breakeven conditions thoroughly

Performance Tips

Keep conditions as simple as needed
Use appropriate timeframes for indicators
Consider market hours for your strategy

Use AI to Create an EAsiScript Preset File

EAsiScript enables you to leverage artificial intelligence for creating preset files and developing trading strategies. By providing AI with your strategy requirements and the EAsiTrader documentation, you can generate compliant preset files that are ready for testing and optimization. This approach combines the efficiency of AI with your trading expertise, allowing you to rapidly develop and refine strategies while maintaining full control over their implementation and risk management.

The key to successful AI-assisted development is providing clear strategy requirements and ensuring the AI has access to all necessary documentation. This section will guide you through the process of preparing your requirements, working with AI to generate preset files, and properly testing the resulting strategies.

1. Prepare Your Strategy Details

Before engaging with AI, clearly define the specifics of your trading strategy:

Entry and Exit Rules: Conditions for opening and closing trades
Risk Management: Stop loss, take profit, breakeven levels, or trailing stops
Indicators: Specify indicators like RSI, Moving Averages, or ATR
Special Conditions: Add any time-based filters, multi-symbol requirements, or other specific needs

2. Upload the User Guides to AI

Provide AI with the foundational documentation:

EAsiTrader User Guide: Core functionality and settings
EAsiScript User Guide: Scripting language and functions
Learn EAsiScript Guide: Examples and best practices

These guides contain all the information AI needs to generate accurate scripts and ensure compliance with EAsiTrader’s requirements.

3. Ask AI to Create Your Preset

Provide your strategy requirements in a clear, structured format:

Specify it must comply with “Rules for Creating Main Preset Files”
Use Defaults.set as template
Request verification against the template
Include specific symbols and timeframes
Detail any optimization requirements

4. Save the Generated Content

Copy AI-generated output to a plain text editor
Save with a descriptive name and .set extension (e.g., TrendFollowing.set)
Verify proper formatting and section structure

5. Copy the Preset File to the EAsiTrader Folder

Locate your MetaTrader data folder path:
- MQL5\Files\EAsiTrader
Place the .set file in this directory
The preset will appear in EAsiTrader’s Profile Dropdown

6. Load the Preset

Open EAsiTrader in MetaTrader 5
Select your new preset from the Profile Dropdown
Verify all settings loaded correctly
Verify required indicators are enabled

7. Test the Preset

Use EAsiTrader’s Tester feature
Start with visual backtesting
Verify entry/exit logic
Check risk management behavior
Test in different market conditions

8. Activate for Live Trading

Complete thorough testing first
Enable Auto Trading in EAsiTrader
Monitor initial trades closely
Keep detailed performance records

9. Iterate and Optimise

Review strategy performance
Identify areas for improvement
Generate new variations using AI
Optimise parameters using Tester

AI Prompt Examples

These examples demonstrate effective AI prompts for generating EAsiTrader preset files and trading strategies. Each example includes the exact text you should give to the AI, formatted with specific requirements and the mandatory preset file compliance instructions.

CRITICAL: INCLUDE THESE INSTRUCTIONS WITH EVERY PROMPT

When providing any of these example prompts to AI, you MUST include these exact instructions as part of your prompt:

“The preset file must strictly comply with all the ‘Rules for
Creating EAsiTrader Preset Files’. Use the Defaults.set Preset File as
a template. Verify your content by cross referencing your sections and
settings with those from the template. Any deviation or omission
will be considered a failure to complete the task.”

⚠️ WARNING: Omitting these instructions from your prompt will likely result in invalid preset files that will not work correctly in EAsiTrader. Remember that the AI cannot see or access these instructions unless you explicitly include them in your prompt.

Each example below shows a complete prompt that you can copy and use directly with AI. Pay attention to how the required instructions are integrated with the strategy specifications in each prompt.
