Question with "Point"

[Forex Trader]

If an EA is attached to a currency pair "EURUSD", some variables/functions will then be based on this currency pair. Point is one of functions.

I would like to write an EA that will manage SL and TP of *ALL* open orders but I dont want to have this EA running on all "currency pair charts". I want a single EA/Script to do all that for me.

Is there any way to know the Point of other currency pair even if said EA/Script is attached to another pair?

Likewise, how would I know the BID/ASK price of other currency pairs?
