It depends on the page you want to have the feedback on - the $post[] array wouldn't be in use on non post related pages for example, but you may be able to use $userinfo[ratetradetotal] if the $userinfo[] array is populated.

It seems unlikely that something wouldn't already have the appropriate field stored if there's anything to do with user details on the page in question - it just depends what you're trying to do.
