Hello! Everything is possible nowadays, the question is “Is it worthy?”
You can predefine the hours of trading in EA Studio and FSB Pro. So when you run the generator they will create EAs that are trading only during these hours.
However, I do not suggest you to use the Forex news as a moment of volatility, because the volatility is not stable there, every time the Forex news are different.
I do not think you will end up with robust strategies.
