At the beginning of 2014, MetaQuotes released MetaTrader build 600, where a completely new mechanism for compiling programs directly into binary code was implemented. After the release of this build, the automatic decompilation of EX4 files became impossible, and the decompiler EX4 to MQ4 v4.0.427.4 has finally become history.
Nothing irreparable has happened. The decompilation of EX4 files is still possible. As before, every trader can use the decompiler EX4 to MQ4 v4.0.427.4 for files that were created before 2014. If you need to decompile a later file or an Expert Advisor downloaded from MQL Market as a demo version, you should contact a specialized online service.
