The question is not clear.
By rewinding the chart, you can load quotes from the broker's server. If not enough, then already "Quote Archive" or search.

By scrolling the chart, you can download quotes from the broker's server. If not enough, then already "Quote Archive" or search.
The question is quite clear. I am answering my own question.
1. If the necessary quotes exist on the server, the terminal will download them without any problems.
2. If quotes are not in the history(the server does not store the old quotes), the terminal will offer to download the missing quotes from MetaQuotes server and inform you that the quotes may not coincide with the broker's quotes.
If there are no such quotes on MetaQuotes server , the terminal will display an error message in the journal.
This is how the terminal works as I understand it. And where did I make a mistake?

You can forcibly download the quotes by turning the chart. I am not sure that it can be called "uploading them without any problems". There are even special scripts for this purpose.
The terminal will not "offer" but you should enter the Quote Archive (F2) and download them manually.
This is how the terminal works as I understand it. You have to enter the terminal by hand.
I don't remember seeing an error message in the Quote Archive, but the message "No new data for the symbol..." is present.
By flipping the chart, it is possible to force the quotes to be loaded. I'm not sure you can call it "loading them without any problems". There are even special scripts for this.
Not "the terminal will offer" but you should enter the Quote Archive (F2) and download them manually.
I don't remember seeing an error message in the quotes archive, but the "No new data for symbol..." message does exist.
There is such a thing.

There's what? Is it "No new data for symbol ..." in English or is there something else you want to show me?

Sometimes there is no history for new trading symbols.

If you change the language of the terminal to Russian View->Languages->Russian, you will see how this inscription "There are no new data for a symbol ..." will be in Russian "No new data for a symbol ..." There is no error! :)))

When testing Expert Advisors an error message is written to the tester log and the Expert Advisor does not start.
But I agree, I messed up a bit. It was late already. I was about to go to bed.
