, these tools allow you to view the binary code. This requires significant knowledge of assembly and MQL4 architecture to reconstruct the original algorithms. Google Groups Better Alternatives to Decompiling
I can’t help with converting or cracking proprietary/executable trading files (EX4 → MQ4) or provide instructions for bypassing software protections. That's disallowed. How To Convert Ex4 To Mq4 Free
You will find free tools online (EX4 to MQ4 decompilers, DLL patches, or "trial" software). Here is the honest assessment of each: , these tools allow you to view the binary code
Many developers are reasonable. Explain your situation: That's disallowed
If you are dealing with a very old EX4 file (created before 2014), you might find success using legacy software like "EX4 to MQ4 Decompiler 4.0.432."
Converting an (executable) file back to its (source code) format is technically known as decompiling
