Excel formula If A is true then check B and if B is negative then return

I have made this code, but how can i get "check positive number" to see if there is a + (or not a - in front of the number?)

=IF(F2="High";IF(E2="Check positive number";"Win";"Loose"))

ok i figured out the code, but how can i have it check for the "low" part in the same cell aswell?

=IF(F2="High";IF(E2>=0;"Win";"Loose"))

And is it possible to add a same type of code but with "low" instead aswell in the same cell? so it checks first for IF high, and if not found it checks for IF LOW?

ok i managed to make it myself, but thanks anyways.

and the code was

=IF(F2="High";IF(E2>=0;"Win";"Loose");IF(F2="Low";IF(E2<=0;"win";"Loose")))
