Here is the detailed post by Beep Beep I'm a Jeep on how the new system works.
https://www.warzone.com/Forum/697546-new-ladder-rating-system-workingThe values since then have changed a bit but not very much.
Stefano is right, the formula to calcolulate the rating can give a negative results. To prevent that it is taken the maximum between your rating and 0. Even if it is showed 0 for you when you finish a game it is your real rating that gets changed. So if you were a lot below 0 it won't look your rating changed, but it did.
EDIT: I checked and your real rating at the moment is -18,2
