Fetcher[
set{hi,days(price reached 52 week high, 100)}
set{lo,days(price reached 52 week low, 100)}
hi above 0
lo above 0
set{diff,abs(hi - lo)}
add column diff
add column hi add column lo


add column abs(hi - lo)
add column abs(lo minus hi)
add column abs(hi minus lo)
]



Seems like it parses past the variable "hi" if the abs command uses "-" instead of "minus"

That is weird. I played around with it, changing the variable names just to see if that made any difference but it didn't (just adding 52 in front). I also added just a 'hi - lo' column to see the actual difference. I found just what you found with the abs function. When I used the "-" symbol it always gave the low number, but when I spelled out "minus" it gave the actual difference.

Maybe someone from the SF team can tell us why.

Thanks for looking into it.

I wasn't going to send a question to SF because usually when I send a "why" question they don't answer it directly; but simply send me back the part of the filter that actually works...like I didn't already have that part figured out.

Generally, it seems that words in SF filters have more capability in certain situations than arithmetic symbols.
