: All comments and original formatting are lost during compilation and cannot be recovered.
Some repos contain "compiled" tools that are actually trojans designed to steal your trading account credentials.
Since late 2013 or early 2014, MetaTrader 4 has used a new compilation method that changed the format of the .ex4 file from bytecode to a more complex binary code. This makes older decompilers (versions earlier than 4.0.509.5, for instance) completely ineffective. Many of the tools you find were designed to work on these older compilations and may not function on recent .ex4 files at all. ex4 to mq4 decompiler github verified
: Decompiling commercial Expert Advisors (EAs) often violates end-user license agreements (EULA) and intellectual property laws. MetaQuotes, the developer of MT4, considers this practice illegal in most jurisdictions.
: It automates the use of the legacy "Purebeam" decompiler by faking drag-and-drop operations. Requirement : You must already own the ex4_to_mq4.exe binary for this to work; the GitHub repo does include the decompiler itself. ex4-to-mq4-2023 : All comments and original formatting are lost
Based on the available evidence and community consensus, here is a summary of best practices.

The EX4 to MQ4 decompiler is a tool used to reverse-engineer compiled MetaTrader 4 (MT4) expert advisors (EAs) and indicators from EX4 files back to their source code in MQL4 (MQ4). This report provides an in-depth analysis of the decompiler, its functionality, and its presence on GitHub.
In the fast-paced world of algorithmic trading, MetaTrader 4 (MT4) remains a cornerstone platform. Traders often rely on Expert Advisors (EAs) and custom indicators developed by third parties. However, if you lose the original source code ( .mq4 ) and only have the compiled binary ( .ex4 ) file, modifying or updating that tool becomes impossible. This is where an is required.
