I used your code from NT to make a horizonal ray.
It works fine when I use price but if I change the code ( line 320 ) to Time it will occasionally shutdown NT - completely.
I mean it can work for 5 hours with no problems but then randomly do this.
any thoughts?
If I change it back to price it doesn't seem to exhibit this behaviour
Edit - I tried changing from panel to ChartPanel but that made no difference
