You can try to post on Russian Python thread here https://www.mql5.com/ru/forum/306688/page72
If not so let me know, and I will post on that thread using html feature (but it will take some time):

You can't do much because the terminal blocks when it's downloading rate data from the trade server. Even if you use async, threading, multiprocessing, you still run into the issue of a blocked terminal on subsequent calls. You could spawn multiple processes connected to multiple terminals and use one worker to handle priority fast tasks and another to handle a queue of long running blocking requests.
Hi,
Could you please elaborator on how to do this "spawn multiple processes" ? I've been trying to achieve this by using multiprocessing and timeout in process.join(timeout=10), but that doesn't seem to work, the terminal gets stuck on updating a ticker and dosen't move on to the next. my code locks something like this:

Set "Max bars in chart" to Unlimited in Terminal:
I am an experienced database developer but a Python rookie.
System W10 on 64 bit.
I get some errors with the installation of the MT5 package, depite that I think I have done everything properly:
* downloaded Python 3.9
* checked the PATH option
* checked that PIP is up to date > "requirements up to date"
* upgraded SETUP and WHEELS
* added ...\Python39\scripts to PATH
* downloaded MetaTrader5-5.0.33-cp39-cp39-win_amd64.whl (122.0 kB)
* pip install MetaTrader5
Anyone? Your help is greatly appreciated!
