Formula to Change Colors If Total Numbers Gain or Lose

Hey Excel Forums, your buddy Noc here ready for round two! I am more of an organizing kind of person, so forgive me if these are really basic problems. Anyway, I am trying to get a system where if the number from the "gain/loss" changes, it will turn green if it gains and then red if it loses. So even if it gains for now, it might decrease from the next update. If it's green from an increase, I need it to turn red if it decreases later. Thank you for having me! Edit: Sorry if I was a little redundant haha.
