Crazy trade assessed (5)
I believe the answer is:
rated
'assessed' is the definition.
(rating is a kind of assessing)
'crazy trade' is the wordplay.
'crazy' is an anagram indicator.
'trade' is an anagram of 'RATED'.
(Other definitions for rated that I've seen before include "esteemed" , "deserved" , "Tread (anag.)" , "Highly valued" , "highly regarded" .)
