I will stick to the second option, since it makes the task much easier, you wait for the real signal and then you start to act, everything is much simpler
Are you sure you can process the signal in time? You can't be tied to a computer 24 hours a day. and automation will not miss anything. I for the first option!
By the way, your words make sense. I also first liked the ability to simply receive signals from the system. But I can not constantly trade. I do not always come near the computer. And the automatic system can earn you money around the clock!
This is created for those who cannot be constantly behind the PC, the automatic system will do everything itself.
