How can I recognize a decompiled code ? - page 3

[William Roeder]

Alireza Yadegar: if the order have an .ex4 file as attachment, is this also illegal? or just a decompiled .mq4 file is illegal?

Humans can do nothing with an EX4 - irrelevant. The exception is you can read an indicator's buffers, but you'd have to work out which buffers and when.
