Good morning,
Please, can someone shed some light on this for me? I'm at my wit's end. I'm trying to do backtesting and I keep getting the same error. Maybe it's something simple I'm missing, but I can't see it. It can't be that it doesn't work on any system. I must be missing something.
The problem is that this structure is not being created. (C:\MT5\Tester\Agent-127.0.0.1-3000\........bases\.... ). No file exists. They are not being created.

I forced the download of candlesticks and ticks without any problems. The folder with the data seems to be fine. (C:\MT5\Bases\WSFmarkets-Server\history\BTCUSD\)
Below I put the log from C:\MT5\Tester\Agent-127.0.0.1-3000\logs\ (this from above) and the one from C:\MT5\Tester\logs\ (without error).
Things I've tried: I've disabled the antivirus and the firewall, given full control access to "everyone" to the c:\MTC folder, the c:\users folder and subfolders, run applications as administrator, and use the /portable parameter to avoid long paths.
Tests with various currencies and brokers.
I've installed both the broker's version and the official version. I've installed it on several "clean" Windows 11 machines, Windows Server, etc.
To see if the data was corrupted, I made a clone of the coin and injected the candlestick data obtained from strategyquant, without success, always the same error.
I would appreciate any pointers, because I'm stuck and I can't see what it could be or how to make it work.
Log from C:\MT5\Tester\logs\, no error.
