Thanks Stefi, this works great but is there a way for it to not highlight
cells that are blank?

Select column D and crate Conditional formatting with this formula:

Is there a way that I can use conditional formatting with an IF
statement?

What I want to happen is, if in column D there appears a number that
has an
opposite match (i.e. 500 and -500) that it highlights those. Is this
possible and if so, how?

Thanks
