Strategy Testing w/ Global Variables From Custom Indicators?

 

So I was finally able to get the EA to read GV's from my custom errors thanks to the help of you fine folks :)

I'm struggling with some back testing on the strategy tester. I can see that the custom indicator is changing the GV value, so I know it is reporting it to the terminal in the back testing. It is also meeting the requirements for opening an order, but it won't open the order for some reason? Are there any types of backtesting w/ GV's that I should be aware about or that I am missing that wouldn't allow me to back test a single indicator and an EA w/ global variables?
