not the worst bug in the world but still a bug is a bug :) Consider a function like this, residing in the mq4 file of a library: #property library // #include <CommonLib.mqh> string PeriodToStr ( int iPeriod ) { switch ( iPeriod ) { case

Hey, a question for somebody from MetaQUotes Soft about the bug tracking web page you have: I have reported several bugs there but never gotten a reply, not even an auto reply. There is no bug number that is assigned to your bug report, you can't see

Loading inputs from a saved .set file after recompilation does not work - it shows the inputs as loaded but they are not! This is obvious by observing the work of the EA (my EA anyway - because I can see from the way it operates that it does not use
