Do you mean the button structure? It needs to be build on the 'on chart' tab as it is now. Don't change that. The launcher should be on the 'on tick' tab, though.
What I would personally do is set up a separate project, put your values into a comment so you can see what's happening on back test. then you can see what needs to be done.
Instead of using the 'x>' symbol you should use this one '>'. And then use a 'counter (pass once)' block below the condition block to specify you need that to happen just once.
