Obviously bug in indicators OnInit() return value effect
It seems return value of indicators is not being respected by terminal. It works for Experts, but not for indicators. Expert code: int OnInit () { printf (" OnInit () returning: INIT_FAILED : %i", INIT_FAILED ); return ( INIT_FAILED ); } Result in Terminal Journal: 2024.01.28 11:15:52.140
Looking for insight to AVX support by MQL5
Hello there, I've been experimenting with AVX (and its derivatives AVX2 + AVX512) support in MQL5. - Assuming, and to some extend verified, AVX is being utilized by the compiler, if enabled, we should be able to see significant speed increase on some types of operations. - Due to the lack of

MetaEditor Shared Projects
I dont even want to start analyzing the issues with the built-in SVN-client in MetaEditor. Just a short explanation why I come to the conclusion, it is inherently broken. And I advise anyone, who would want to use it for shared colaboration on a project, to step back from using it. Here is what
MathMax/MathMin giving (maybe) wrong results.
While working on the project "Build an API-Tracer", which is finally done and published, I came across this "issue". Is this considered a bug? Or not. To my understanding it is a bug. Print ( FLT_MAX ); Print ( LONG_MAX ); Print ( MathMax ( FLT_MAX , LONG_MAX )); This code will give
Interesting finding in MQL4 (not for real use....)

AlgLib contains ArrayReverse functions
I have noticed, AlgLib from standard library overwrites the original functions from MQL. Interestingly, it doesnt make any sense, because the included function is slower than the original MQL-Function. //+------------------------------------------------------------------+ //| Array reverse (uchar)
