Estimated distribution of trade (5)
I believe the answer is:
rated
'estimated' is the definition.
(I've seen this in another clue)
'distribution of trade' is the wordplay.
'distribution of' is an anagram indicator.
'trade' with letters rearranged gives 'RATED'.
(Other definitions for rated that I've seen before include "Had a high opinion of" , "Classified or graded" , "Castigated" , "Admired" , "esteemed" .)
