It appears that I have solved this problem. The arrows only show up when the condition is true and you will see these in the buffers (you can see these in the data window (under View/Data Window). They do not show up as objects (see fxdreema's tutorial on this below).
The correct way to do this is to load the indicator under "my indicators". Then this dialog box was the correct way to do it
Hi: I am trying to get a buy or sell when an arrow shows up on a custom indicator. There are 2 buffers (red and blue). Issue a buy when blue arrow is true, sell on the red arrow.
I have attempted a number of tries and this link shows the condition as being a boolean statement which of course does not work. I would appreciate the help!

I got it to work, just used 1H and 4H. Not sure if this is what you are looking for.
