how to automatically run a script when MT4 start

 
I only have one script, but I've attached it to every chart (symbol). But everytime I start MT4, I have to re-attach the script ... Is it some error in my code?
 
As designed.

You can attach one script for automatical running via start configuration. F1 - Client terminal help - Tools - Configuration at Startup

That's a little complicated. I prefer manually...
