My guess is yes.
My oldest machine is a Samsung laptop, i3, 8GB, 380GB, CPU running at a measly 2.53GHz. Windows 7 Home Premium 2009! This thing is ancient in tech years. Yours likely isn't far behind in age. Although my Samsung runs the main MT5 terminal without any issues, I would never even try to run a backtest on it.
MQ continues to update MT5 with various additional features which, over time, increases the load on a computer (specifically, its CPU). Everything ran fine on old machines at the advent of MT5, but we're way beyond that now.
Sorry to be the bearer of bad news.
I understand my friend... my laptop is about 4 years old... I'm already planning to buy a new, better one... but I'm doing it within the limits of my financial possibilities. But thank you very much for telling me. I'll take this into consideration.
It looks like you don't understand me, but I don't know how to say it more clearly: you need to provide exact logs if you want real help from other people in the troubleshooting.
Hi friend... please, how can I provide you with the exact logs? Look, I do my backtest like this:
- entire history
- m1
- 1:100
- and I don't use visual mode, in order to make it lighter.
Is that it? (I'm still learning about MQL5)

Logs are text files with *.log extensions, generated by the terminal itself, by MQL5 programs, and by the tester agents - all placed in different folders, visible in different tabs in the UI - yes, this feature probably requires some reading of the docs and understanding about the platform. These files contain important information for troubleshooting.
So my friend, in this case, the problem is possibly that my laptop is too "simple"?
My laptop: HP i5, 8gb, 250gb
my backtests often use 34gb of memory, and my optimizer uses minimum of 300gb of hardrive space; when testing my own ea, therefore "too simple" could be the issue. The age of your compu ter isnt tho, as i have used 25 year old computer to trade and backtest a simple ea several times.
But your windows version could certainly be another issue. If you are using less than windows 10, then, you may not have the required web extensions for metatrader to run optimally.
And all this back test data would help in live trading ? , No and the coder probably over optimized it in the first instance ! .
Blaming the MT5 Tester is getting a bit old in this forum. The greater industry environment in which the whole of MT5 exists creates most of the issues. MQ never claimed that the Tester would mirror live trading and MQ openly publishes the Tester's limitations. As far as I'm concerned, the Tester is a godsend for testing code and confirming long-term (10 to 20+ years) profitability of custom strategies.
The word that you're searching for is "overfitted."
