I’m holding a proprietary MetaTrader 4 indicator that exists only as an .ex4 file. My sole aim is to study and understand its internal logic, so I need the file professionally decompiled into a clean, readable .mq4 source without altering a single behaviour. The finished .mq4 must mirror the compiled version in every respect—calculations, signals, inputs, visuals, alerts—everything. In particular, the arrows/objects the indicator draws and all data buffers are non-negotiable priorities; they must be preserved exactly as they appear now. Feel free to use the usual reverse-engineering toolchain (MetaEditor, IDA, Visual Studio, or your preferred assembler plugins). Just ensure no new bugs slip in and no existing functionality goes missing. Deliverables 1. A fully working .mq4 file that behaves identically to the supplied .ex4, including all buffers, arrows/objects, alerts, and input parameters. 2. A brief read-me outlining any code sections that required special handling so I can follow the logic easily. I’ll provide the original .ex4 as soon as we start. If you have prior decompilation work you’re proud of, mentioning it will help me gauge turnaround expectations.
