Added display and selection of compilation mode directly in the toolbar:
The nastiest thing happened (b4040): backtest result depends on compilation instruction set selection.
The sizes of tst files are 1.5 times different: 13 (AVX) and 17 (X64 Regular) megs. To say that it sucks is nothing to say.

Is just the test working properly?
Need a benchmark to answer this question.
If different test behaviour, look for your UB. If it's just the size that confuses you, that's fine).
What is it?
What is it?
Undefined behaviour, it seems. It's undefined behaviour.
Then the advice is worthless.

I'm not talking about where it is correct, but about the testing mode.
You can try to start with simple Expert Advisors trading at the opening, i.e. exclude the influence of tick history.
On a small number of trades compare the report and visually study the discrepancy.
