@Vladimir Karputov

I asked, you ignored the question. I'll ask again.

as I understood when changing TF on the chart the whole history of trading session is reset ? bx, opening .the same - starts over again ! is it so intended ?

I am not Vladimir, of course, but yes, that is the way it is designed. There is no writing to the file!

[Aleksey Vyazmikin]

This indicator is very slow - I don't know what is slowing it down, but it's a fact.

As for writing to a file, of course, when a new bar appears, it would be good to write it and read it when initialising....

I have said more than once: it is designed that way. Who does not believe - can look at the code.
