table conditional formatting less than 0

Hi, 

i am trying to format my table. rule is simple

  1. if less than 1 then  downward red arrow

  2. if equel to 1 then  

  3. if bigger than 1 then upward green arrow

however i am not able to do this simple rules

1, I may have nagitive number, but the first rule not let me input the nagitive number 

2. I only have simple rule, if i do can input the nagitive number but i WNAT everything just below 1 which means I need to put 'negative infinity' there. could I just only have one part of condition ?

thank you!
