I don't remember how to learn from 0... I didn't have such an opportunity... When I started learning MQL in MT3, I was programming for about 25 years...

Well, I understand from the posts that the man does not have the necessary knowledge (teaching is light).

It's not like the thread is called learn to read the Help ;))

Here is an example of my training https://www.mql5.com/ru/forum/111497/page257#219531

or rather, searching for functions...

Try it by trial and error, not like that then how ?

read the HELP :)

If the terminal hangs when inserting the indicator, it means that the loop is infinite?

didn't understand what I'm supposed to get clearer from this cycle?)
eddy:
I don't understand, what should become clearer to me from this loop?)

How loops work,

that variables declared globally can be applied to all code functions,

how and what the function returns,

its call,

reference to an array outside the given function,

perpetual loop with interrupts,

...

gone to the barber ;)))
