Hello, Vladimir.
Your last post may well illustrate the difficulty that authors of educational materials inevitably face: it is not known what set of concepts a potential reader may operate with. Based on your words in your last post, you have a normal idea of the meaning of the foreign word "identifier". Though judging by your question about the word "handle", it was impossible to assume such a thing in advance. That's why everyone who tried to answer you tried to randomly choose some different set of basic concepts that you most likely know exactly. And on their basis to give you a definition of hendle that is understandable to you. Hence the differences in explanations.
Yes, you are right. I can even explain why that line
I "got it." )
When I was reading this line in my head instead of the word identifier, the word number came to mind, and then this:
Something like that. ))

Hello Maxim, I have finally found the clearest explanation of what a handle is in one article on the MQL5 website.
Regards, Vladimir.
is a local interpretation of a handle. So to speak, they wanted to do it the best, but did it the same way as always :-)
In some places, "handle" is a separate data type, uninputable, so that curious people don't ask questions "why is there 4 there and 17 there".
As a subscriber you only control the deposit percentage allocated for copying ("Use no more than %") and global limits such as "Stop if equity is less than…".
Position size is calculated automatically according to the balance/leverage ratio and the percentage you assign. The provider's SL/TP levels can be copied or not, but you cannot enforce your own per-trade risk settings.

it's a local interpretation of hendle.
It is better to have such an interpretation, which somehow explains the meaning of the word handle, than no interpretation at all. I wouldn't be surprised if many other foreign words used in the colloquial usage of MQL5 programmers also have a local interpretation. The main thing is that it should be understandable to ordinary people with zero level of training and knowledge in programming. )

I quote you:"The desire to understand at the developer's level appeared to me in the times of the Soviet Union, when I worked as an electronic engineer and studied the element base of computers of EU series. It seemed to be enough to know that microcircuit K155LA3 has..."
a person with engineering education (even more so practice) of the times of the Soviet Union is not zero level in any field at all. You have locked yourself in somewhere and do not let your intellect go free.

I had absolutely zero level in programming. Now this level is a bit higher than zero. ))
Now concerning foreign terminology in programming. Maxim, if there is no other UNDERSTANDING (thorough) explanation of a foreign word, I have to make do with what is slightly acceptable to me. ) Besides, now, at my age, it is not so easy to understand anything as it was 40 years ago during the Soviet Union!
Yes... Those were the times!!!

Please forgive me for being a bit off-topic. We electronic engineers had (maybe still have) such a concept as "half of it". Sometimes we used to say phrases like: "There is a half-half hanging on the input of the lashki!". I don't know what will be clear to you now, but we understood that we were talking about a microcircuit of 155 series of LA type (take the same K155LA3), which has neither zero nor one at its input. The question may arise - how so!!! All logic is based on the state zero or one, and here it is like this! That's why I had to understand not only the algebra of logic, but also to study the circuitry of the chip itself. )

I've never heard of a half, but just a "hanging input" - yes. It hangs and catches interference.
I once observed an interesting picture in "Iskra-1030", as K155TM2 has a level on the direct output and a meander on the inverse output (or vice versa, I don't remember). Although, it seems, R and S are connected to +5 by a resistor.
I've never heard of a half, but a dangling input, yes. It's dangling and picking up interference.

Nah, I haven't encountered Iskra, because in my time there were "dinosaurs", starting with EU-1020 series and ending with EU-1060. I have not encountered a case like yours either. The only explanation I see is that the outer leg of the chip (no matter which one - direct or inverse output) had no physical connection with the internal circuit, i.e. there was an internal break in the chip. )
