eDownPercentOpen Filter

In my testing I found the answer to your problem:

if Filter(eDownPercentOpen,-100,-5) then

The eDownPercentOpen value will be something like a -7 for down 7%. Therefore it has to be in the range of the lowest (1st) value of -100 for 100% down, to a highest (2nd) value of -5 for 5% down. Sorry the order of the parameters for negative numbers was confusing.
