Expert advisor for multiple stocks

Hi ,
Is there a way that I run the expert advisor script for multiple stocks (example Nifty 50) all at once like how we do for scanner,
Opening the stocks of all the charts and applying EA is a lengthy process.
Also in scanner if the equation is true, the line blinks so we need to keep monitoring it continuously,
In case of EA at least there is an alert sound.
Your help is highly appreciated.
