TheXpert:

And buffers are OK, you can put them in classes, give them aliases and search by aliases.

It's simpler, you put them into structures and make an array of these structures. Index accesses.

... But it was 512 somewhere, so I don't know.

It flashed from me. ) I double-checked it just in case. Yes, it's 512. If you make e.g. 513, an error message comes out when compiling:

I can't quite figure out how to do it, what functions do I need to use to do it?

situation-open order in mt4. when the time comes to close it- press X in the trade window- where is the end of the order line. how is the closing procedure carried out? what labels. deal identifiers are transmitted?

i>The understanding is needed for a bigger problem.

when an investor's account is opened, all of the manager's orders that were previously opened are copied to it.

the top priority is to find out how to copy only new orders opened and closed by the manager after attachment of an investor's account.

if you know how to do it - describe it in detail.

if you know what is impossible, please justify the reasoning.

It also depends on the leverage, for example if you have 1:100 and a provider has 1:500 you will copy lots 5 times less. Try to test on demos with different leverages.
