Can EA apply in all currency pair?

Since the creator has said only few pairs can be traded, but I found out that others are also profitable. So can I just add it to the chart and let it start trading? or it is some kind of creator setting?

Depends on how it is coded. Does it trade the current symbol with no hard coded dependencies?

How we should know restrictions without code?

But when I back test, it is ok to trade other pairs. Is it matters?

Vague questions, results in vague answers. We have less knowledge than you. Ask the creator.
