To clarify, I do use the heatmap previously developed in response to an earlier request, and I'm grateful for it, but there are two issues with it:
1. the Alert only applies to the OB/OS levels, not the slope of the line which would be useful;
2. While the OB/OS alert works, the colours for slope up/down seem to work for the selection of SMI/Signal line only for the first slot and for the remaining slots the slope seems to apply to the Signal line even if it is the SMI line that is chosen..
Thanks for your help guys!
