The software is running out of memory.
Out of memory error pops up after 3-4 days of expert work.
I don't know how to catch it.
I have placed a bunch of printers, monitor all the arrays for overflow.
I have an idea to speed up the program. I want to speed up the program, for example, I want it to make 10 thousand passes instead of one. But in order to filter blocks gradually, we need to control the memory load.
We can do it with MT4, but the accuracy there is up to one megabyte.
If you want to use dll, there is theGetProcessMemoryInfo function in winApi(https://docs.microsoft.com/ru-ru/windows/win32/api/psapi/nf-psapi-getprocessmemoryinfo?redirectedfrom=MSDN_).
It is supposed to be able to trace up to a byte.

Hello!
I have a problem.
MT4 is missing, i.e. whole periods are not displayed. For example, in the attached screenshot on franc on H4 whole 10 days are missing. I tried to upload quotes via Service-Archive Quotes, the quotes are loaded normally but it does not help. I have tried restarting the terminal too. I have to download quotes for more than one symbol.
How to help?
I would be very grateful for advice.

Try PKM on chart --> Refresh. On each timeframe.
Or, on each TF, hold down the Home key until everything has booted up.
Try PCM on the chart --> Refresh. For each timeframe.
Or on each TF hold the Home key until everything loads.
HELPED!!! Thanks, good man!!!

Could you please tell me if it is possible to set font thickness on text objects?
FoundTextSetFont (Sets font for text output by drawing methods)https://docs.mql4.com/ru/objects/textsetfont
, which has flags to set font thickness, but can't figure out how to use it.
