lol, I consider myself a happy customer and so happy when I like a product to tell people about it (if I am unhappy with a product I will also tell people about it...).
EA Labs has a bunch of pre-defined indicators in the menu on the left of the EA Lab window, but Zig-Zag is not one of them. This means if you want to use that concept you will have to write your own functions to simulate it, which may be possible (I don't understand Zig-Zag very well) but its certainly extra work - I had to do this to create the HA bar functionality I posted about previously and am now using in one of the EA's I'm demo testing.
If you dont mind me asking how did you test Zig-Zag and get results if you haven't coded it?
