Hello Tomasz,
first of all: Thank you very much for such an excellent piece of Software. I'm new to AB, came across AB and just astunished (performance, backtesting capabilities, AFL) -> WOW
Please continue your great work!
Regarding this topic: I do see your point. But the program from Fred "MCO" effectively leverages the other cores by assigning a dedicated task (optimizer) to a certain core. Isn't that an option for you / AB?
All the best
Frank
