Turned to trade, perhaps (7)
I believe the answer is:
rotated
'turned' is the definition.
(rotating is a kind of turning)
'to trade perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'to'+'trade'='totrade'
'totrade' is an anagram of 'ROTATED'.
(Other definitions for rotated that I've seen before include "Turned around axis or central point" , "took part in revolution" , "Had spin" , "Turned in a circle around an axis" , "Turned round" .)
