I found the file. I had to give the program administrator rights so that it could save to the file.
Now I have another question.
How to determine the last operation number to insert in OrderSelect()?
I'm doing this
It says that total = 322
But there are zeros in the file
I did the following
OrderSelect(total-1,SELECT_BY_POS,MODE_HISTORY);
And everything worked )))
Is this correct or it may cause an error in time?
I.e., may it accidentally return the value not of the last order in the history but of some other one?
Can you tell me if it makes a difference if you write
or
if(условие && условие && условие) { ... }
Why does this "trawl" get the error "OrderModify error 1" in the tester every second and in large quantities? Logs just swell to gigabytes... What needs to be fixed?

There is, of course, some common sense in the search hints, but you could have just written: yes, there is. And explain in a nutshell that the use of logical comparison in 4 is not organised optimally.
