I've got a quick question. My broker, IBFX, recently sent this to me...

"If you compiled an Expert Advisor or a Script in build 213, MetaTrader has informed us that you will have to recompile it once you update to Build 214/215.
To recompile go to:
Tools
MetaQuotes Language Editor (F4)
Double left click your Expert Advisor or Script in the Navigator
Left click on the Compile button
Exit MetaQuotes Language Editor"

My question is, what does recompiling do to an EA/script?

Thanks
