Is it possible to change the symbol of a chart within EA

 
I am writing a Hedge EA will change the pairs of symbols from time to time according to some calculation. I want to change the symbol of the chart that my EA attached to. So that I can show the correct symbol that my EA currently taking. Is it possible?
 
Why you want to change Symbol of a chart within EA? MQL4 language provides all needed functions for access to any allowed Symbol.

Dear Rosh,

It is because I want to watch my EA on how they are behave, you know, if I run my EA several times and I want to see the the symbols that match my EA currently ticking, I have to drag and drop each symbol to the charts say ten or twelve time. It is troublesome. So I want my EA will automically selected for me. Thanks.
