Understanding EX4 and MQ4 File Formats in MetaTrader 4
MetaTrader 4 (MT4) uses specific file formats for programming and coding. Traders and developers must grasp these file types to manage trading algorithms and expert advisors well.
In MT4 programming, two main file extensions are key: EX4 and MQ4. These formats are important for creating and compiling expert advisors.
Key Differences Between EX4 and MQ4 Files
Developers using MQL4 coding will work with two file types:
- MQ4 Files: These are source code files that are easy to read and edit.
- EX4 Files: These are compiled binary files that MetaTrader 4 can run directly.
The Role of File Extensions in MT4 Programming
File extensions are crucial in MT4 programming. They show how trading algorithms are processed and run in MetaTrader 4.
| File Type | Purpose | Characteristics |
|---|---|---|
| MQ4 | Source Code | Readable, Editable, Requires Compilation |
| EX4 | Compiled Script | Machine-Readable, Executable, Compressed |
Source Code vs Compiled Files
In MT4 programming, knowing the difference between source code and compiled files is key. MQ4 files are the original, editable scripts. EX4 files are the optimized, executable versions for trading platforms.
Developers can change MQ4 files directly. But, EX4 files need decompilation to edit them. This makes keeping the source code important in MQL4 coding.
Benefits of Converting EX4 to MQ4 Expert Advisor
