is it possible to unload and reload an indicator inside an EA?

 
Hi,
I want to reset an indicator loaded in my EA. Because this indicator has a small repaint issue, once a signal set, the indicator didnt revert back the signal to empty by it self.
today my only option is to change the currency where my EA is set or recompile my EA or eit the EA properties and close them; all of these actions unload all the indicators used and reload them.
but I cant do this all the time manually.
and so... I'm looking for possible code which can unload an indicator or reset it.

any idea?
I dont have access to the code of the indicator I'm using, so I can't solve the problem here.

thanks.
