To Txt Top — Ex4
In the context of MetaTrader 4 (MT4), converting an (executable) file into a
or readable source code format is a reverse-engineering process known as decompilation Blackwell Global Summary of the Process
file is a compiled binary that contains machine instructions for Expert Advisors (EAs), indicators, or scripts. Unlike files, which are plain text source code, files are not human-readable. Standard Method : There is no "Save As" function in MetaEditor to turn an executable back into a text file. Decompilation Tools : Specialized software like the EX4 to Multiple Readable Language Converter EX4 to MQ4 Decompiler are often used to attempt to recover the source logic. Challenges with Modern Builds
: Since Build 600, MetaTrader has implemented stronger encryption and compilation techniques. Most modern
files will only produce "gibberish" or broken pseudocode if run through older decompilers. Google Groups Technical Write-up Breakdown
If you are writing a report or walkthrough on this topic, consider these key sections:
Converting an file (a compiled MetaTrader 4 file) into a readable
source file is a common request for traders looking to modify indicators or experts. However, because .ex4 files are "machine code," they are not meant to be read by humans. 1. Understanding the File Types
: The executable version of a script, indicator, or Expert Advisor (EA). It is compiled and ready to run in MetaTrader 4.
: The editable source code. This is what you would need to convert your file into if you want to see the logic in a text format. 2. Is Conversion to Text Possible?
There is no direct "Save as Text" button for an .ex4 file. To view it as text, you generally have two paths: Option A: Decompilation (The "Technical" Path)
Decompilation is the process of reversing the compiled .ex4 back into an .mq4 source file.
: There are third-party "EX4 to MQ4" decompilers, though many are outdated or considered unreliable for newer builds of MetaTrader. Legality/Ethics
: Decompiling software may violate the developer's terms of service or copyright laws in your region.
: Even if successful, the resulting code is often messy, missing variable names (e.g., using ), and difficult to read compared to the original. ex4 to txt top
Option B: Accessing the Values via Data Window (The "Practical" Path) If you just need to see the
data (the numbers the indicator produces) in a text-like format: Open MetaTrader 4. to open the Data Window
Hover your mouse over the chart. The Data Window will show the specific values for every buffer in that .ex4 file for that specific candle.
You can then manually export chart data to a CSV/text file by going to File > Save As while the chart is active. 3. How to Use the .ex4 File Directly
If you cannot get the source code but still want to use the indicator's logic in your own EA:
function in MQL4. This allows your own code to "call" the .ex4 file and pull its data without needing to see the underlying source. 4. Summary Table: EX4 vs. MQ4 No (Binary) Yes (Source Code/Text) Trading Execution Development Conversion Requires Decompiler Just click "Compile" in MetaEditor , or are you looking for a way to extract chart data to a text file? MQL4 Reference - MQL4 Documentation
The phrase "ex4 to txt top" typically refers to the search for the best or highest-rated tools and methods to decompile or convert MetaTrader 4 (MT4) executable files ( ) into readable source code or text formats ( Top Methods for "EX4 to TXT/MQ4" Conversion Converting a compiled file back to text is a process known as decompiling
files are "bytecode" (machine-readable), they are not natively readable as text. Pure Decompilers (Software Tools)
Historically, tools like "EX4-to-MQ4 Decompiler" were popular for older builds of MetaTrader (Build 600 and below).
files use strict encryption, making simple "one-click" text conversion tools largely obsolete or unreliable for the latest versions. Manual Decompilation Services
Since automated tools often fail on new MT4 builds, "top" results usually point to professional services where experts manually reconstruct the code logic into a Online Converters Several websites claim to offer instant conversion. Caution is advised
, as these are often used to distribute malware or steal proprietary trading algorithms. Why Users Search for This Code Recovery : A developer loses their original source code and only has the compiled Strategy Analysis
: A trader wants to see the underlying logic, indicators, or "magic numbers" used in a commercial Expert Advisor (EA). Modification
: The need to change parameters or fix bugs in a tool that no longer has developer support. Technical Challenges Encryption In the context of MetaTrader 4 (MT4), converting
Converting an file (a compiled MetaTrader 4 program) directly to a readable
file or source code is extremely difficult because it is machine-executable binary code, not plain text.
While there is no "top" official converter that provides a perfect one-click solution, here are the most effective methods and tools available: 1. Advanced Decompiler Tools (Recommended)
These tools analyze the binary structure to generate pseudocode or text descriptions of the logic. AdibSadman192/Ex4-to-Multiple-Readable-Language-Converter
: A powerful GitHub tool that allows you to select an EX4 file and output it as Text (Plain description) , or even Python/C. How it works
: It uses a disassembly engine (Capstone) and control flow analysis to reconstruct the logic into three tabs: Raw analysis (JSON), Pseudocode (selected language), and a Debug Log. Purebeam EX4 to MQ4 Decompiler (Older Builds) : Effective only for files compiled with MetaTrader 4 build 509 or lower
(pre-2014). It cannot handle modern EX4 files which use stronger binary compilation. 2. Manual Analysis (Alternative)
If you just need to see if there is any readable text inside the file (like copyright info or server links): Hex Editors : Use a tool like 010 Editor
. This will not give you the source code, but it reveals raw binary data and any embedded text strings. Data Window (Ctrl+D)
: If you just want to see the values an indicator is generating (the "output" text), attach it to a chart in MT4 and open the Data Window
. Hovering over a bar will show the numerical values for every buffer. 3. Critical Limitations Modern Encryption
: EX4 files from recent MT4 builds (600+) are compiled into machine instructions, making clean recovery of the original MQ4 code practically impossible. Broken Logic
: Even "successful" decompilations often result in random variable names (e.g.,
) and incomplete functions that are hard for humans to read. Legal Risks Contact the developer and request the
: Decompiling software may violate the original developer's terms of service or local laws. setting up the GitHub decompiler mentioned above, or are you looking for a specific version of an older indicator?
Option 1 — Get the original MQ4 source (recommended)
- Contact the developer and request the .mq4 (source) file.
- If you own the code, retrieve it from backups or version control. Why: This preserves comments, variable names, and exact logic.
The Important Distinction
- Decompilation (Code Recovery): Trying to convert the
.ex4back into readable source code (.mq4). This is generally not possible and often illegal/unethical. - Binary-to-Text (Data Viewing): Opening the file to see its header information, strings, or binary structure. This results in a messy text file but is technically a "conversion."
Option 3 — Recreate logic manually by reverse engineering behavior
- Run the EX4 in MT4 with test data or strategy tester.
- Log its inputs, outputs, and runtime behavior (trades, indicator values, alerts).
- Re-implement equivalent logic in a new MQ4 or any language and save as TXT. When to use: when decompilation isn’t possible or allowed.
Part 5: How to Protect YOUR EAs from Being Converted (For Developers)
If you are a developer worried about others using "EX4 to TXT top" on your work, take these steps:
- Use the MQL5 Cloud Protector: MetaQuotes offers official obfuscation that is currently unbreakable.
- Add integrity checks: Make your EA check for debuggers or virtual machines and crash if found.
- Use license servers: Require online validation for critical logic.
- Compile with latest MetaEditor (build 1355+): Newer compilers produce code that is extremely difficult to decompile.
The Elephant in the Room: The EX4 Protector Arms Race
Why is there no perfect "ex4 to txt top 1-click tool"? Because the developers fought back.
In response to decompilers, modern EX4 files are wrapped in protectors (e.g., .ex4 protector by ex4store). These tools:
- Encrypt the actual bytecode.
- Add anti-debugging routines (the EA will self-destruct or trade randomly if tampered with).
- Bind the EA to a specific MT4 account number.
Thus, the "top" EX4 to TXT converter of 2025 does not exist publicly. The legal and technological arms race has ended in a stalemate.
Summary
Converting an EX4 file to a TXT (source code) file is not a standard file conversion. It is an attempt to reverse-engineer a compiled program.
- If you are the developer: You should keep your own backups of the
.mq4source files. - If you are a user: You generally cannot convert EX4 to text. If you need to modify the logic or understand the strategy, you must contact the original coder to request the source code. Beware of online tools claiming to perform this conversion, as they are often scams or malware.
Converting an (a compiled MetaTrader 4 program) directly into a readable TXT
or source code format is a common challenge for traders looking to audit or modify indicators and Expert Advisors (EAs). Because EX4 files are machine-readable binaries, they cannot be opened as text without a conversion process. Top Ways to Convert EX4 to Text/MQL4 Ex4-to-Multiple-Readable-Language-Converter : This is a modern open-source tool available on that can analyze EX4 files and generate pseudocode in Plain Text , MQL4, Python, or C. Decompiler Services
: Historically, traders used dedicated decompiler software to turn EX4 back into MQ4 source code , which is a standard text format that can be viewed in the MetaEditor MQL5 Forum & Community Support
: For specific indicators where you lack the source code, community members on platforms like Forex Factory
often share text-based versions or provide advice on how to extract parameters. Key Considerations Editing vs. Viewing : You only need the EX4 file to
the program in MetaTrader 4. You only need the text/source version (MQ4) if you intend to
: Many EX4 files are protected. Decompiling copyrighted material may violate licensing agreements
3. Legal Liability
Most commercial EAs (purchased from the MQL5 marketplace or vendors) are protected by copyright. Decompiling violates the MetaTrader 4 license agreement and the Digital Millennium Copyright Act (DMCA). You could be sued.
