revers45:

Can you advise where to read about using .Net libraries in MQL5 programs? I haven't found the appropriate section in the documentation.

Look in the articles.

Look in the articles.

I'm not interested in tricks, but in a standard feature, since it has been officially declared.
For example, there are suggestions in the articles to do this through export of unmanageable code https://www.mql5.com/ru/articles/249.
But as far as I understand, integration via decompilation is a hacking technique... I read somewhere on a forum that MQ sued hackers.
So, this method would be just right, as an argument, in such a lawsuit ...)

Write a non-dotnet dll and use it normally in the terminal like other dlls. To support dotnet libraries, we use a transparent wrapper that supports native calls.

I tried it, but it didn't work. If I specified the function name with name space and class name, as in C#, the MQL5 compiler doesn't pass it and if I specified just a function name, it is not in the runtime of EX5 in the terminal.
Probably some additional notation is required to explicitly point to .Net attributes, if I could see a simple example...

This article is about an additional layer for MQL5 programs, in the form of win32 dll QExpertWrapper.dll, which in turn works with .Net, and my question is about using .Net dll directly in MQL5 programs.

Thanks, what you suggested is another interpretation with dll intermediary (wrapper), but for MQL4.
I was doing it approximately the same way, but why should I need all those tricks, decrease reliability and put a different wrapper on each library, if it's already in the terminal...
Show me just a little example of how to use it, this transparent staff vrapper...

I rewrote my robot from MQL4 to MQL5 with difficulty. In the tester the TakeProfit parameter is not optimised and trades are not closed by it. I have noticed that I have already traded in the trading robot, but I have not found it and it is not working correctly. What is the reason.

From time to time some "crap" happens: the optimizer doesn't start, I thought the processor might be too busy or something. Today I rebooted WIN XP, deframented the disk, started the optimizer:

IQ 0 04:19:14 Tester Experts\Smart Neurons Test.ex5 on EURJPY,H1 from 2003.06.01 00:00 to 2013.06.01 00:00

II 0 04:19:15 Core 1 connected
QP 0 04:19:16 Core 1connection closed

It works the second time, i.e. I pressed "stop" then "start", and it's not the first time.
