G001 Thank you, and how do you know the maximum allowable volume with this function?

I'm not familiar with MT4. I need to know the maximum allowable volume of what?

In general, this function is easy to use: we enter 1.0 as a volume and obtain the margin for a single lot order. And then the proportion (I cannot recall right now between what and what exactly).

Hello. Please tell me if there is a ready solution (class) to show entry/exit levels with arrows when an EA is running. Like in the visual mode of the tester.
 

Question about the tester, I start to test the Expert Advisor, the tester works, but the amount of memory used is growing, the amount of memory used is increasing, the count goes to gigabytes. I use instances of classes in the Expert Advisor, which I do not close in any way, should I do it forcibly? Maybe there are already written articles by someone? The memory is released only when I close the terminal, is it normal?

Also, why when I close the tester, it continues to run as a process without freeing memory

Thanks
