Indi changes effective immediately ?

i'm sure this is a simple question that has been answered before but not sure where !

So u are making changes to an indicator - do u always have to restart mt4 for those changes to be effective or is there a way to make them ready without always restarting ?

thx

no need to restart if you are changing the programming of an indicator, just re-compile it and you are ready to go.

knew it was easy ...
thx
