MetaQuotes (the developer of MT4) introduced significant changes to the EX4 structure around build 401 (released in 2013-2014). Version of the decompiler is specifically designed to target EX4 files compiled with MetaTrader 4 builds from 401 to approximately 600. This makes it a "golden era" decompiler—compatible with thousands of EAs created during MT4’s peak popularity. While a human can deduce that g_124 is
