EA on several accounts on one platform


Hi guys,

A few general questions about EAs, appreciate the help in advance:

1- I installed the EA on my laptop and I have several demo and real account active on my computer. Say that I drop the EA on one FX chart(i.e. activate the EA for that currency pair), will the EA place trade all the accounts on my laptop (demos+reals)?

2- What is the best way to stop the EA for currency pair? If I closed the chart window, would it stop the EA on that currency pair?

3- Is there a tutorial/video archive library to learn these small things about EAs anywhere on the web? anything you would recommend?
