My core isn't used at 100% when I''m testing my expert

Hi,

When I'm testing experts advisors, some of them use 100% of my core. And some, doesn't use more than 8% of capability.

Actually, both experts are almost the sames, only few lines and indicators changes.

Do someone have an idea of what cause this problem ? And how could I fix it ?

MT4 or 5

There is nothing to fix.

It does not matter if it is on MT4 or MT5, a single back-test pass will never use 100% CPU.

Only when doing optimisations on MT5 will it use multiple threads/cores.
