Using All CPU Cores

[Trader2381]

How can mt5 use all cpu cores? Right now, it only uses one core, which is the one that I assign it to by right-clicking and pressing "select". Thank you :)

thanks, I already read through the documentation and didn't find an answer. "Allow to use > local agents" is selected but it only uses 1 agent (1 core) instead of using all of the cores which is what it is capable of/supposed to do, right?

Hi,

If you run only one settings, 1 core will be used.

If you run optimization, all cores will be used.
