I had this issue as well. Seems to be related to the latest Chrome background throttling nonsense. They can´t be disabled anymore via the flags menu in the latest Chrome builds. Launching chrome.exe with these command line parameters should help:

--args --disable-features=RendererCodeIntegrity --disable-background-timer-throttling --disable-renderer-backgrounding --disable-backgrounding-occluded-windows --js-flags="--max_old_space_size=32768"

It´s also always a good idea to use optimized Chrome builds from RobRich, they are much faster than the Google Chrome releases. I´d recommend to pick the AVX version:

Yes. The RobRich builds are based on Chromium, which is the base for Chrome and is open source. Google simply adds their stuff on top of Chromium and releases it as Chrome. Internal it is exactly the same, so also accepts the same command line parameters.

i cannot get in run constantly good. i use only 3 tabs now with chromium with the parameters. let it run after a week i loook. both are crashed..than all running process  was for free.

i didnt get it run stable. and i only use 50000 bars each tab.

hello
I have the same problem.
The program starts calculating very quickly but when 7 days pass, the program starts to slow down and sometimes stops.
I have a ryzen 9 and 64 Gb ram.
The cpu does not exceed 80% and the memory 40%.
I load 25000 bars in h1
I have tried with several browsers and with the modified version of Chrome
The problem occurs with one or more windows.
I did not have this problem several months ago. I think the problem started in October + -.
I'm sorry for my English
a greeting

Hello
I believe that I explain myself incorrectly.
The program starts very fast, and after about 7 + - days, the program begins to slow down, after a few more days 3 or 4 the program works in jumps to stop and start. It happens with different currencies, and with a single window or 6 windows, the number does not matter.

I only use the pc to generate expert advisor. I restart the pc every time I do a new search.
I have checked the memory and it is fine, the processor does not heat up.
Does anyone use the 15 or 30 day program? and the program runs at the same speed,
Do you have the problem that the program starts and stops?

I am currently using chromiun with a new search.
It is in the phase that works fast, I put some captures, do you see the data you need correctly?
Do I have to expand a capture area?
I have changed the size of the paging file to larger I do not know if it will affect.
a greeting
Thank you

I do not have a collection saved, when I do a new search I only import the configuration, the old collection I download and delete it.

In a few days when the program becomes slow and starts to stop I will upload some screenshots again
