Comrades I can't understand why CSV files are not created, everything worked before.
Terminal version and bit mode
MT4 409
Problem description
When attempting to write into a text file with FILE_READ|FILE_WRITE key without explicitly setting the file pointer using FileSeek() function, the writing does not occur at all. No error is generated.

More info
In previous versions of the terminal, when reading a text file using FileReadString() fuction, it was automatically set a file pointer.
The last change in the file functionality is from the middle of 2008.
Never before has it been possible to append to a file without first setting a file pointer to the end.
Again a question about the extra information. Does this have anything to do with appending to the end of a file?
Any file read-write operations automatically move the file pointer around. This has always been the case and hasn't changed. However, if the file is opened as a csv, intermediate data buffering is possible. Then the file pointer may not be where you expect it to be. Again, this has always been the case, both in the previous version and in the pre-release, since the beginning of the official release.
We have reiterated many times that the default principle is extremely detrimental. Including for file pointers. Handle file pointers explicitly unless you're using continuous read or continuous write (especially the exotic case of mixed read-write)
It has FileSeek in both cases
Hello, could you please tell me if anyone knows how to write this condition in the code?
(level is defined as a moving average)
1) The EA opens 2) Checks if there is a "working" order:
A) there is one and when the price reaches a certain level, you have to close it and open a reverse order.
B) if there is no order and when the price reaches a certain level, you should close it and open a reverse order.
Thanks in advance for your time...!

1) The EA opens 2) Checks if there is a "working" order:
A) there is one and when the price reaches a certain level, it is necessary to close it and open a reverse order.
B) if there is no order and when the price reaches a certain level, you should close it and open a reverse order.
Thank you in advance for your time!

Only files with FILE_READ | FILE_WRITE key will not be created.
Huge problem.
I download MetaTrader4 web version installer (<0.5Mb) from any broker.
Installation goes fine. When I try to enter the program, it starts and immediately exits.
What is the problem and how to solve it?
