Conditional formatting (Iconsets) based on delay

If I correctly understand, you want to display Icon Set not just plain background color in cells. If so, try the following solution.

See the screenshot. Sample data is in Cells D4:E10, which is your sample variance data.

In F4 put the following formula and drag it down along the length of table.

=IF(AND(D4<=0,E4<=0),3,IF(OR(D4<=0,E4<=0),2,IF(AND(D4>0,E4>0),1)))

Depending upon your regional settings, you might need to use ; instead of , in the formula.

Now for convenience set the font color same as cell color. Mostly white. So the numbers will be invisible.

Select the set of cells from say F4:F10 and apply Conditional Formatting --> Icon Sets of your choice. I have selected Green, Yellow, Red.
